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

The wide flange provides better load distribution than standard external push rings and can be used to cover oversized holes. Also known as thread cutting nuts.

Thicker than standard external retaining rings, these rings withstand greater force.

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

For a smooth profile and better clearance than standard external retaining rings, the lugs on these rings point inward.

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

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings.

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

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

Slide these rings into a groove near the end of the shaft and the tab locks them in place.

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.
