External Retaining Rings

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

Heavy Duty External Retaining Rings

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

Inverted External Retaining Rings

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

Side-Mount External Retaining Rings

Also known as E-style rings.

Heavy Duty Side-Mount External Retaining Rings

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

Low-Clearance Side-Mount External Retaining Rings

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

Wide-Grip Side-Mount External Retaining Rings

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.

Heavy Duty Spiral External Retaining Rings

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

Single-Turn Spiral External Retaining Rings

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

Spiral External Retaining Rings

These coiled rings can be wound into place on a shaft without tools.

Clip-On External Retaining Rings

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

Push-On External Retaining Rings

No groove required—press these rings onto the end of a shaft for a firm grip.

Rectangular Push-On External Retaining Rings

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

Push-On Retaining Caps

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

Speared Ends External Retaining Rings

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

Push-On Internal Retaining Rings

No groove required—these rings have teeth that firmly grip the bore.

Single-Turn Spiral Internal Retaining Rings

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

External, Internal, and Side-Mount
Retaining Ring Assortments

These assortments include pliers to install external and internal rings.

Rectangular Push Nuts

Also known as flat-style speed nuts, these have large sides, so they're easy to push over threads by hand.
