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, 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.
