💡 What’s the role of a keyway in a clutch bearing?
A keyway locks the bearing to the shaft, preventing slippage and ensuring direct torque transmission. It adds security and strength, especially in applications with stop-start cycles or rotational loads.

A reliable pick for one-way motion control where precise engagement is critical.
