D1300 and D1400 Circlips
A circlip is a type of retaining ring or fastener that takes the form of a flexible, open-ended ring, made from metal. They may also be known as retaining rings, snap rings, c-clips, or Jesus clips.
Most applications which need a part to pivot, spin, or turn, where a bearing is used, will need a circlip or lock ring fastening. Circlips are commonly used in motors, turbines and pistons.
Circlips fit into a groove on the inside of a bore or the outside of a shaft. They work as a load-bearing shoulder which positions and holds mechanical parts. They provide continuous radial force and are secure against high rotational speeds because they are retained within the groove.
