By enhancing friction between joint components, 3M™ Friction Shims allow higher power densities in automotive and other applications.
Higher Torque. Same Bolt Connection.
In automotive engineering, wind energy and many other industries, there is a general trend towards compact, lightweight designs with maximum power density – and high reliability. However, in order to transfer high loads in friction joints such as shaft-collar or bolt connections, the size or number of components typically needs to be increased. 3M™ Friction Shims offer a proven and cost-effective alternative: by increasing the coefficient of friction between components, they allow transmission of up to 4x higher torques – without requiring modification to the joint design.
Proven Reliability in a Variety of Industries
We have supplied millions of 3M friction shims for demanding automotive and motor sports applications, power generation and other industries where components must be reliably joined together to transmit forces and torques. Our technical specialists have many years of industrial experience, and conduct in-house testing to meet our customers' specific requirements. Thanks to this expertise and extensive testing, we have over 100 million friction shims in use with no reported failures in the field.
