C-RING

A C-RING is an open circular retaining component, also known as a circlip or C-type retaining ring. Depending on the installation position, it can be classified into external shaft rings and internal bore rings. Once installed into a shaft groove or housing groove, it helps limit the axial movement of bearings, gears, bushings, and other components.

Provides Stable Axial Retention

Once the C-RING is seated in the groove, it forms a retaining surface that helps limit the axial movement of bearings, gears, bushings, and other components.

Available for Both Shaft and Bore Applications

External retaining rings can be selected for installation on shafts, while internal retaining rings are designed for installation inside bores or housings, allowing them to match different mechanical structures.

Saves Assembly Space

The thin circular structure occupies relatively little installation space and can replace certain nuts, end caps, or washer-type retaining arrangements.

Easy to Install and Remove

The ends of the C-RING are provided with plier holes, allowing installation and removal with suitable retaining-ring pliers. This makes equipment assembly and maintenance more convenient.

Wide Range of Applications

C-RINGS are commonly used in motors, bearings, gearboxes, pulleys, automotive and motorcycle components, electronic equipment, and automation mechanisms. When selecting a C-RING, confirm whether an external shaft type or internal bore type is required.
