A ROTATING shaft can exhibit torsional vibration when, because the dynamic coefficient of friction is less than the static value, the frictional force at the bearings supporting the shaft decreases as ...

Rotary actuators produce oscillating power by rotating an output shaft through a fixed arc. They are compact, simple, and efficient. They produce high instantaneous torque in either direction and ...

Machines that turn, eject, cut, and spray rely on efficient, automatically reversing linear motion. Rolling-ring linear drives are commonly used in these types of applications because they eliminate ...
