Daemar’s line up of Retaining Rings provides design engineers with non-threaded fastener solutions that answer the challenge of an economical design that reduces weight, size, raw materials and labour. Knowing which ring to use in a given fastening situation can greatly contribute to the overall effectiveness and economy of a design.

Simplify Assemblies and Reduce Costs
|
|
Simplify your mechanical assemblies, reduce installation costs and decrease material waste by incorporating retaining rings into your designs. Retaining rings perform a range of versatile functions allowing manufacturers to replace more costly components including: machined shoulders, cover plates and screws, cotter pins and washers, and set screw collars. Once installed, the rings provide a protrusion or “shoulder” for retaining parts.

Rings for End-Play Take Up
|
|
Retaining rings can act as a spring or as a preload in part assemblies to reduce chatter or vibration. Bowed retaining rings are designed to compensate for accumulated tolerances in assemblies and Beveled retaining rings are designed to eliminate end play by wedging itself between the groove and the retained part.

Retaining Rings Design Considerations
|
|
Several factors can affect your decision when selecting the best retaining ring for your application. These include: how the ring is to be installed, shaft & bore size, shoulder size, thrust loads and rotational speeds. A range of materials and finishes are available to select from to best match the application’s environmental conditions. Our website has the resources to help you select the correct product for your application.

Self Locking Retaining Rings - No Groove Required
|
|
If the assembly you must retain is characterized by very little thrust load, consider a self-locking retaining ring. These require no groove and are ideal for use on shaft/housing diameters of 1” or less. They save machining time and overall costs since a groove is not needed for installation. They also come in small sizes (some fitting shafts as small as .058” in diameter) and can be used effectively and economically on small applications with very low thrust loadings.
