3M™ Friction Shims

Downsizing doesn't have to mean a downgrade in performance. From wind turbines to automotive engines – wherever components must be reliably joined together to transmit forces and torques – 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 have been successfully used in a wide variety of industries, including: automotive engineering, motor sports, railway, marine engineering, general mechanical engineering, machine tools, robotics, turbines, and wind and water power generators. Our technical specialists have many years of industrial experience, and conduct in-house testing to ensure that 3M friction shims meet our customers' specific requirements.
 

• Micro-scale interlock with the joint surfaces
• Adjustable and reproducible surface properties
• Enables lighter weight, more compact designs
• Static friction increase up to a factor of 4
• Easy assembly and reassembly
