Optimizing Design: Doing More With Less

  • Automotive manufacturers face increasing pressures to do more with less. Engineers are looking for solutions to reduce vehicle weight without sacrificing overall vehicle performance and power.  3M™ Friction Shims, can provide solutions by reducing component size and increase performance – all while allowing a greater margin for safety.  Enabling the freedom and flexibility to design lighter, more powerful and reliable engines and power trains.


    3M™ Friction Shims provide a simple, cost-effective and technically mature solution. These proven materials help answer the demand for maximum power density – enhancing friction to transmit higher loads while enabling more compact and lightweight designs. 3M friction shims reliably transmit up to 4x higher torques than conventional systems, without requiring modifications to the joint design.


    3M™ Friction Shims as a standard design component to help:

    •     Increase engineering design flexibility

    •     Achieve power density targets with downsizing / increasing performance

    •     Reduce slippage with greater torque capacity

    •     Help maintain project timelines

Compact Construction Without Compromises

  • 3M™ Friction Shims consist of a coated steel shim with partially embedded diamonds. When the shim is placed between two components in a bolted connection, the diamonds grip into the surface, creating a microform fit and significantly increasing friction between the two parts.


    4X Higher Friction Coefficient

    The friction coefficient of over 0.6 (which corresponds to one to four times higher torque) when using 3M™ Friction Shims permits more compact and lighter drive components - without the need for any compromise in stability and reliability.


    Design Flexibility: No Design Change Required

    3M friction shims are thin enough to fit within close engineering tolerances, creating possibilities for lightweight compact design while increasing potential load and peak torque in bolt connections.


    Proven On-Road Solution to Reduce Risk

    3M Friction Shims are a reliable technical solution with more than 180,00,000 used in automotive manufacturing with no reported field failures!
