2144-5144
Retaining rings for shafts

Retaining rings for shafts 2144-5144 in inch dimensions are the heavy duty version of 2133-5133 and are suitable for applications with vibrations or high speed rotations.
Compared to the standard series, they require greater force when assembled, thus ensuring greater safety against rotation of the ring on the shaft and a better performance of rotation speed (RPM).
