Grooveless Retainer Rings

Grooveless Retainer Rings

Superior stainless steel fastener, grooveless retaining ring provides 360 degrees of bearing surface for maximum holding power....without a groove!

Tinnerman Grooveless Retainer Rings (stainless steel fasteners) press over studs, shafts, or any round shape from .046" to 2.00" diameter..G-R-Rs become an integral part of the axial application, replacing snap or bearing rings, cotter pins, staking,swaging, spinning, heat forming, ultrasonics, coining, cementing, or upsetting...grooveless retaining rings eliminate high-cost operations.

Grooveless retainer rings (stainless steel fasteners) are designed without slots, or shears, G-R-R's will not "walk-off" or spring free. Low profile flat designs require a minimum of space. Wall dimensions as thin as .024" make this type of retainer ring ideal for limited access locations. A grooveless retainer ring (stainless steel fastener) needs as little as .032" of shaft or stud extension for full anchor.

Quality stainless steel retaining rings assure long life, corrosion resistance, minimal distortion, dry finish, eliminates heat treat, finish and handling operations...and the extra costs they entail.

A full range of grooveless retaining ring sizes has been developed on modular tooling. Virtually any unlisted size that falls within the limits of the tools can be made, for a one-time set up charge. Any size grooveless retainer ring (stainless steel fastener) beyond this range can be made but requires tooling.
