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.

Single-Turn Spiral External Retaining Rings

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

Push-On Retaining Caps

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

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.

Single-Turn Spiral Internal Retaining Rings

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

Push-On Internal Retaining Rings

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

Side-Mount External Retaining Ring Assortments

Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface.
