Product Description
What are retaining rings?
Retaining rings, also called circlips or snap rings, are open-ended ring fasteners installed in grooves on shafts or inside bores. They provide a compact shoulder that locates components and resists axial movement.
Working Principle
How this spring type works.
The ring is elastically expanded or compressed during installation and then returns toward its original diameter inside the machined groove. The groove transfers axial load from the retained component through the ring into the shaft or housing.
