Rotor Clip Company, Inc. manufactures a full line of inch, DIN, ANSI metric, and JIS retaining rings to world standards, as well as a complete line of constant section rings, spiral retaining rings, and wave springs.

Retaining rings are metal fasteners that are installed into a groove on a shaft or in a housing or bore creating a shoulder that retains an assembly. They eliminate threading, tapping, drilling, and other machining operations associated with more traditional fasteners like screws, nuts, bolts, cotter pins, and washers. They can significantly reduce production costs since the grooves can be machined with other production processes. They provide a more compact, functional design overall than their traditional counterparts.

Retaining Rings

Tapered Section – Axially Installed

  • Axially installed into machined grooves in housings/bores (internal) or on shafts (external)
  • Have lug holes for ease of installation/removal
  • Make uniform contact when released in a groove
  • Can accommodate higher thrust loadings

Tapered Section – Radially Installed

  • Radially installed into machined grooves on shafts (external)
  • Accommodate lower thrust loadings than axial retaining rings
  • Do not have lug holes: Easy to install using retaining ring applicators
  • Provide protruding “shoulders” for effective retention of assemblies
  • Economical alternative to Axially Assembled external tapered section rings

Self-Locking and Push-On

  • Can be installed on a shaft or in a housing/bore without a groove
  • Save on machining time and costs since no groove is needed
  • Can be used effectively and economically on small applications
  • Accommodate low thrust loadings
  • Difficult to remove once installed

Constant Section

  • Axially installed into machined grooves in housings/bores (internal) or on shafts (externally)
  • Offer more clearance that a tapered section ring
  •  Accommodate less force than a tapered section ring
  • Uniform material width is elliptical when installed in a groove, making 3 point contact
  • More difficult to install/remove
  • Economical alternative to tapered section rings depending on the application


  • Axially installed into machined grooves in housings/bores (internal) or on shafts (external)
  • Make 360-degree contact with a groove in a housing/bore or shaft
  • Offer more clearance than a tapered section ring
  • More difficult to install/remove
