CS-RING Structure

CS-RING

A CS-RING is an open, round-wire shaft retaining component installed in an external groove around a shaft. Once seated in the groove, it helps limit the axial movement of bearings, gears, pulleys, bushings, and other components. Its circular cross-section fits closely against the groove base, making it suitable for shaft-end retaining structures with limited installation space.

Round-Wire Structure Fits the Groove

The circular cross-section fits into the shaft groove and seats against the groove base, forming an axial stop that helps restrict the axial movement of mating components.

Compact Installation Space

The compact ring structure can reduce the need for nuts, end caps, and multiple washers, making the CS-RING suitable for small assemblies or mechanisms with limited shaft-end space.

Elastic Tension Maintains Retention

The CS-RING elastically deforms during installation. Once seated in the groove, it recovers toward its original shape and maintains spring tension, helping reduce the possibility of accidental disengagement.

Available in Metric and Imperial Sizes

Metric or imperial specifications can be selected according to the shaft diameter and groove dimensions, making the CS-RING compatible with different machinery and component systems.

Suitable for Various Shaft Assemblies

CS-RINGS are commonly used in motors, gears, bearings, pulleys, automotive and motorcycle components, electronic equipment, and automation mechanisms.
