Open these rings, pass them over the end of a shaft, and release to spring into the groove.

These rings meet military specification MS 16624.

No groove is required for these rings—their thick profile helps them grip the shaft.

Also known as E-style rings.

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.

Slide these rings into place with one twist—no tools required—for applications with high thrust loads.

Often used with small engines, heavy equipment, and power transmission, these external retaining rings have speared ends to help you install and remove them.

Use these caps to hold components in place and protect shaft ends.

Also known as flat-style speed nuts, these have a large surface to distribute loads better than standard and flanged external push rings.

Also known as constant-section rings, these rings have open ends and a profile that does not taper like other external retaining rings. Use them with linear bearings on support rail shafts.
