Retaining Rings

Also Called: C Clips, C Retaining Rings, E Clips, E Retaining Rings, External Retaining Rings, Internal Retaining Rings

Use retaining ring pliers (see separate listing) to install External Retaining Rings--the rings expand to pass over the shaft when opened by the pliers. They seat into a groove in the shaft when released by the pliers.

External C Retaining Rings are ideal in low-clearance situations especially where exposed tabs are neither required nor desirable. They snap into a groove in the shaft from the side.

External E Retaining Rings have a larger profile than C Retaining Rings. They are also installed by snapping them into a grooved shaft from the side.

Internal Retaining Rings are compressed to fit inside a housing or bore using retaining ring pliers (see separate listing). When the pressure is released, the rings expand and lock into a groove.
