G-RING

A G-RING is an elastic retaining component installed in an external groove on a shaft. Its shape features an open ring structure with a clamping section. It can be pushed axially into a pre-machined groove to limit the axial movement of components such as gears, bearings, bushings, and pulleys.

Provides Stable Axial Retention

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

Suitable for Thrust Load Applications

The clip-type structure works together with the shaft groove to withstand axial forces, making it suitable for mechanisms requiring reliable axial retention.

Simplifies the Assembly Structure

A G-RING can reduce the need for nuts, end caps, and multiple washers, helping simplify both component count and shaft-end design.

Provides Consistent Installation Positioning

When installed according to the specified groove diameter, width, and depth, the G-RING helps maintain consistent component positioning and assembly spacing.

Suitable for Various Transmission Components

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