Also known as C-style and crescent rings, these rings have a small shoulder to fit in tight spaces.

These rings are reinforced to withstand faster rotation than other side‐mount retaining rings. Also known as reinforced E‐style rings.

Also known as bowed E-style rings, these have a curved design that works like a spring, taking up play for a tight hold.

Thicker than standard spiral rings, these rings withstand greater forces.

Slide these rings into place by hand with a single twist for applications with high thrust loads.

These coiled rings can be wound into place inside a bore or housing without tools.

Wind these retaining rings into a groove—no tools required for installation.
