When robotics teams engage FTL

Start with the programme or performance situation that has created the requirement.

A new axis or joint needs a friction solution

The duty is understood, but the friction material, component construction or repeatable manufacturing route still needs to be established. FTL can support the route from technical review and material development through prototype manufacture, testing, validation support and controlled repeat production.

A holding brake is not behaving as required

The engineering team is seeing drift on a held axis, inconsistent stopping, excessive or unpredictable wear, thermal concerns, or variation between units or production batches. FTL can review the application, current component, friction material, operating conditions and available evidence before proposing the next engineering step.

A legacy material or component is no longer available

The original material, drawing, supplier or complete component has become obsolete, while the installed base still requires a dependable supply route. FTL can review the available component and application information before proposing redevelopment, prototype, testing and revalidation work.

The current supply route has too many handovers

Material formulation, machining, bonding, finishing and inspection are divided among separate suppliers, creating unclear responsibility when quality or performance questions arise. FTL can connect the relevant stages through one accountable manufacturing chain.

The programme needs repeatable and scheduled supply

The requirement must move beyond initial samples into controlled manufacture, traceability, inventory holding, scheduled call-off and international delivery.

Where FTL friction components work inside robotic systems

FTL supplies friction materials and complete components into these areas today. The right route for a given axis depends on the duty, the operating environment, the space available and the evidence the solution must provide.

Industrial robots

Holding and braking components for the axes of industrial robot arms, where a joint must hold position under load and arrest motion predictably across a long service life.

Collaborative robots

Compact, low-mass friction components for cobot joints, where the brake has to fit inside a slim housing and behave consistently from cold.

Robotic joints

Friction materials engineered around the joint itself: the holding torque required, the envelope available, the thermal path out of the assembly and the cycle life expected.

Robotic arms

Fail-safe braking for arm axes, where the brake must hold the arm and its payload safely on power loss as well as at rest.

Holding, braking and controlled-motion components within robotic systems

Beyond the named classes above, FTL supplies the friction components that hold, stop and control movement wherever they sit inside a robotic system. FTL formulates the material and machines it to the finished component under one roof, including Kevlar, sintered and composite formulations suited to compact, dry-running, high-cycle duty. FTL also works with raw-material suppliers already established in the robotics sector, so material selection starts from proven robotics-grade inputs.

This page describes an engineering and manufacturing service. It is not a list of stocked components or a claim that one material is suitable for every robot design.

Define the application before selecting the friction material

A material family, coefficient value or existing part number does not define a complete solution on its own. FTL begins by understanding what the component must do and the conditions under which it must operate.

01

What is the application?

Share:

  • The component's function
  • Which axis or joint it sits in
  • Whether the requirement concerns a material or a complete component
  • What has prompted the enquiry
02

Is this a new design or an existing component?

Confirm whether the project involves:

  • A new programme
  • An existing component under review
  • An obsolete component
  • A supply-continuity problem
  • A performance concern
  • A prototype moving towards production
03

What operating conditions are known?

Useful information can include:

  • Holding torque required
  • Duty cycle and expected cycle life
  • Temperature and available thermal path
  • Speed at engagement
  • Dry running or lubricated
  • Available installation envelope
  • Particulate or cleanliness constraints
  • Known wear or thermal concerns
04

What technical information is available?

This can include:

  • Drawings
  • Partial drawings
  • Specifications
  • Existing components
  • Material information
  • Performance requirements
  • Inspection records
  • Test results
  • Batch or production records

A complete technical pack is not required before the first conversation.

05

What must the solution demonstrate?

The programme should establish:

  • Required holding and braking behaviour
  • Wear expectations across the cycle life
  • Thermal requirements
  • Dimensional requirements
  • Bonding or assembly requirements
  • Inspection requirements
  • Acceptance evidence
  • Validation responsibilities
06

How will the component be supplied?

Later programme discussions can cover:

  • Prototype quantities
  • Expected annual volumes
  • Repeat-production schedules
  • Inventory holding
  • Scheduled call-off
  • Packaging
  • Labelling and identification
  • Export and delivery requirements

Expected annual volumes and detailed commercial qualification are discussed after the initial application and technical fit have been established.

What FTL can deliver within a robotics programme

Not every project requires every stage. FTL can support one part of the programme or connect the route from custom friction-material development, through component engineering, machining, bonding, finishing, testing and inspection, into traceable repeat and lifecycle supply.

A controlled path from robotics requirement to repeat supply

The detailed route varies by project, but each stage should provide enough evidence to support the next engineering decision.

01

Establish technical fit

  • The application
  • The required function
  • New, existing or obsolete
  • Current programme stage
  • Performance or supply concern
  • Information available
Decision: does it fit FTL's capabilities?
02

Define operating and performance requirements

  • Holding torque required
  • Duty cycle and cycle life
  • Temperature and thermal path
  • Speed at engagement
  • Installation envelope
  • Dry running or lubricated
  • Existing performance evidence
  • Inspection and documentation needs
Decision: what must the solution demonstrate?
03

Establish the material and component route

  • Whether an established material may suit
  • Whether formulation work is required
  • Whether the component also needs development
  • Which manufacturing stages apply
  • Which information remains unknown
Decision: what route progresses into prototype planning?
04

Agree the prototype and test plan

  • What FTL will manufacture
  • Which variants will be assessed
  • Which dimensions or characteristics inspected
  • Which tests FTL will complete
  • What evidence is required
  • FTL responsibilities
  • Customer or third-party responsibilities
Decision: what must the prototype stage establish?
05

Manufacture the prototype components

  • Material-production stages
  • Machining
  • Bonding
  • Surface preparation
  • Finishing
  • Assembly
  • Inspection
Decision: suitable for the agreed test stage?
06

Test, inspect and review

  • Agreed testing and inspection completed
  • Evidence reviewed against requirements
  • Material, geometry or route refined where needed
Decision: further development, or progress?
07

Support the agreed validation route

  • Engineering, manufacturing, test, inspection and traceability evidence within scope
  • Final machine, cell, customer or regulatory approval responsibilities agreed per project
Decision: has the route completed required approvals?
08

Transfer into controlled repeat supply

  • Repeat-production controls
  • Inspection and traceability requirements
  • Inventory holding
  • Scheduled call-off
  • Customer-specific packaging and identification
  • Export documentation
  • International delivery
Decision: what supply arrangement maintains continuity?

The evidence robotics buyers need before approving a route

Can FTL match or improve the required performance?

FTL can review the current material, component, operating environment and required behaviour before proposing an established, optimised or newly developed material route. Whether performance can be matched or improved depends on:

  • Available application information
  • Defined operating conditions
  • Existing component evidence
  • Agreed test conditions
  • Acceptance criteria
  • Component construction
  • Validation responsibilities

No outcome should be guaranteed before that work has been completed.

Will the material hold up over a high cycle count?

Cycle life is a design requirement, not a property of the material alone. It depends on the holding torque, the energy absorbed at each engagement, the thermal path out of the joint, whether the brake runs dry, and the envelope available. FTL formulates for compact, dry-running, high-cycle duty and can assess an application against those constraints, but the expected life for a given design is established through the agreed test programme rather than quoted in advance.

How does FTL support consistent quality and repeatability?

The available route connects:

  • Friction-material formulation
  • Component engineering
  • Machining
  • Bonding
  • Finishing
  • Testing
  • Inspection
  • Production documentation
  • Batch and lot traceability

The exact control plan and acceptance requirements are agreed for the individual programme.

Can FTL support more than material supply?

Yes, where the programme fits FTL's confirmed capabilities. FTL can support:

  • Material development
  • Complete-component engineering
  • Prototype manufacture
  • CNC machining
  • Bonding and finishing
  • Testing and inspection
  • Repeat manufacture
  • Inventory and worldwide delivery
How quickly can FTL support the programme?

There is no standard lead time for every robotics project. Timing depends on:

  • Information available
  • Material-development work
  • Component complexity
  • Prototype iterations
  • Testing and inspection
  • Customer validation
  • Production quantities
  • Supply requirements

FTL should confirm proposed stages and timing after the initial technical review.

Select the friction-material route around the complete joint assembly

Material selection should consider the required holding and braking behaviour together with the component, operating environment, production route and evidence needed for approval.

The final decision

The appropriate route may involve:

  • An established material
  • Optimisation of an existing formulation
  • A newly developed material
  • A component change alongside the material
  • Further application evidence before a change is recommended

Published data is a starting point. Final material selection depends on the application and agreed validation route.

Keep the friction material connected to the finished component

A fragmented route can divide material development, machining, bonding, finishing, inspection and supply among several organisations. FTL can connect those stages through one engineering and manufacturing chain, keeping the material, component and production decisions aligned with one technical and commercial point of accountability. Actual lead-time, procurement or cost improvements depend on the current supply arrangement and agreed project scope.

Engineering capability backed by controlled manufacture

SDTS approached FTL after the original aircraft brake pad was no longer available. FTL worked with SDTS to redesign the pad, establish a suitable material route and manufacture a component aligned with the stated aeronautical technical requirements. The work supported SDTS in certifying a modification applicable to its aircraft.

To continue flying our aircraft, we approached FTL to find replacement solutions for our brake pad problem, as the original part was no longer available on the market. The quality of our discussions, from both a technical and commercial standpoint, FTL's responsiveness in redesigning the pad with a material that meets aeronautical technical requirements, and their ability to adapt to our aeronautical environment allowed us to certify a modification applicable to our aircraft. The quality of the manufactured product is remarkable. Thanks to FTL, we can continue to fly, land, and brake safely.

Frequently asked questions about robotics friction materials

What robotics applications does FTL supply?
FTL supplies friction materials and complete components into industrial robots, collaborative robots, robotic joints and robotic arms, and more broadly the holding, braking and controlled-motion components within robotic systems.
What friction materials does FTL work with for robotics?
FTL's stated material families include organic, composite, sintered, Kevlar and woven. For robotics duty the assessment usually centres on compact, dry-running, high-cycle behaviour. The appropriate material depends on the joint, operating environment, complete component and agreed validation requirements.
Does FTL manufacture complete components or only friction material?
FTL can support both. The available route can include friction-material formulation, component engineering, CNC machining, bonding, finishing, assembly, testing, inspection and repeat supply.
Can FTL support a new robotics programme?
Yes. New Programme Support can cover the route from application review and material development through prototypes, testing, validation support and repeat manufacture.
Can FTL reverse engineer an obsolete robot brake component?
FTL supports legacy and obsolete friction-material and component projects where the original drawing, material or supplier is unavailable. The existing component and application evidence are reviewed before a redevelopment, prototype, test and revalidation route is proposed.
Can FTL investigate drift, inconsistent stopping, wear or thermal problems?
Yes. FTL's confirmed performance-optimisation scope includes inconsistent braking, excessive or unpredictable wear, and thermal-performance concerns. The review can consider the friction material, complete component, operating conditions and available production evidence.
Can FTL work to a tight installation envelope?
Compact duty is a normal robotics constraint and FTL formulates for it. The envelope, the holding torque required and the thermal path available are all inputs to the technical review, and the achievable design is established through that review rather than assumed.
Can FTL guarantee improved performance?
Not before the application, evidence, operating conditions, test scope and acceptance criteria have been reviewed. FTL can propose and test an improvement route, but no outcome should be guaranteed in advance.
What information should we provide?
Useful starting information includes the axis or joint, whether the requirement is new or existing, what the component needs to do, holding torque, duty cycle, temperature, available envelope, drawings or specifications, current components and existing test or inspection information. A complete technical pack is not required for the first conversation.
What testing and inspection can FTL support?
Depending on the agreed scope, FTL's stated capabilities include CMM dimensional inspection, dynamic and material testing, coefficient-stability assessment, wear-rate assessment, thermal-performance testing, shear testing, in-process checks and final component inspection. The precise samples, test conditions, methods and acceptance criteria must be agreed for the project.
Who is responsible for final validation?
Responsibilities must be defined for each programme. FTL can provide the engineering, manufacturing, testing, inspection and traceability evidence included in its agreed scope. Final machine, cell, customer or regulatory approval may remain with the customer or another appointed authority.
Does FTL stock robot brake pads by part number?
FTL is structured around custom engineering and manufacturing requirements rather than stock catalogue sales. A part number can provide useful background, but FTL will still need to understand the application and technical requirement.
Can FTL support customers outside the UK?
Yes. FTL manufactures in North Wales and supplies components worldwide. 84% of output is exported.
