E-Style Retaining Rings are available in standard or metric sizes, and in 18-8 stainless steel or in steel with a black oxide finish at Fastener SuperStore.

Designed for radial / vertical installation into machined grooves on shafts, E-rings require a deeper groove, but provide exceptional thrust loadings when compared to fasteners of the same size and weight. Steel rings can be safely used within a temperature range of -100°F to 500°F. Stainless steel rings are corrosion resistant & can be used in higher heat applications from -100°F to 900°F.

External Style Retaining Rings are available in standard or metric sizes, and in 18-8 stainless steel or in steel with a black oxide finish at Fastener SuperStore.

The external retaining ring is for axial assembly into machined grooves on shafts. The tapered section design assures uniform circular deformation, allowing for complete contact and tightness in groove. Steel rings can be safely used within a temperature range of -100°F to 500°F. Stainless steel rings are corrosion resistant & can be used in higher heat applications from -100°F to 900°F. (Spec Sheet)

Internal Style Retaining Rings are available in standard or metric sizes, and in 18-8 stainless steel or in steel with a black oxide finish at Fastener SuperStore.

The tapered section design assures constant moment and, therefore, uniform circular deformation; allows for complete contact and tightness in groove. The internal design is for axial installation into machined grooves in housings and bores. Steel rings can be safely used within a temperature range of -100°F to 500°F. Stainless steel rings are corrosion resistant & can be used in higher heat applications from -100°F to 900°F. (Spec Sheet)
