Retaining Rings & Snap Rings

Retaining rings, also referred to as snap rings, primarily provide shoulders to locate or retain parts on shafts or in cylinders. Advantages of retaining rings are their economy of manufacture, ease of assembly and accuracy of positioning as compared to threaded fasteners.

The two major categories of retaining rings are internal and external:

  • External retaining rings are assembled over a shaft
  • Internal rings are assembled in a cylinder

Special application rings can be produced in a wide range of sizes from a variety of ferrous and non-ferrous materials as well as various material shapes:

  • Rectangular
  • Square
  • Round
  • Tapered
  • Beveled

Associated Spring is capable of manufacturing custom retaining rings in a multitude of sizes with oblique configurations in the free-state to maximize ring concentricity in the groove at the installed position. For applications requiring axial load in addition to the radial load at the installed position, Associated Spring can manufacture custom retaining rings with axial waves to meet both requirements.

We are also capable of engineering and manufacturing retaining rings with special end configurations and tabs to locate the retainin ring within the assembly and prevent ring rotation in the application.

Our custom engineered and manufactured retaining rings are available with or without special coatings for lubricity and/or corrosion protection.

Our retaining ring product line services the Transportation, Aerospace/Defense, Medical, Industrial, Durable/Commercial Goods and Electronics markets.

Associated Spring facilities are third-party certified to AS9100, ISO9001 or TS16949 and ISO 14001 depending on the markets serviced.

How to Specify:

A blueprint or sketch is the best way to specify your retaining ring/snap ring requirements. Consultation with Associated Spring engineers early in the design stage will often result in lifecycle cost optimization.
