Snap Rings

Acme Monaco’s snap rings (retaining rings), which include internal, external, and specialty rings, are dependable, tight, burr free, clean cut, and concentric in the assembled position. We can manufacture complex custom snap ring designs to tight tolerances. Our unique process and proprietary engineering software allow us to produce snap rings with the highest performance to ensure the success of your application.

Internal Rings

These rings are manufactured to compress into a bore diameter and assemble or “snap” into an internal groove for retention.

The rings are elliptical in the free state to ensure maximum contact in the assembled position.

External Rings

These rings are designed to expand over a shaft and “snap” into a groove for assorted retention applications.

Specialty Rings

The parameters of establishing the specifications, physical properties, and characteristics of custom-made retaining rings include:

  • Type of material
  • Thickness, width, and cross-section material
  • I.D. (inner diameter) of external ring
  • O.D. (outer diameter) of internal ring
  • Gap in assembled position
  • Atmosphere in use
  • Any special requirement

All retaining rings are manufactured to your specific OEM applications.

Order Quantity

You can order millions of parts and schedule shipments for uninterrupted supply, or we can tool up and run a few hundred.

Packaging Options

Packaging is important for protecting the parts before they are placed in use. Whether you need bulk pack, right-side up, tangle-free, or one-at-a-time, we’ll get the parts to you on-time, the way you need them.
