MW Industries, Inc. manufactures custom, precision-engineered retaining rings (also known as coil rings, coiled rings, snap rings, round wire rings, circlips, square section rings, rectangular section rings, custom shaped section rings, or tapered section rings) that are available in various end configurations and used in multiple applications.
Function of Retaining Rings (or Snap Rings)
Retaining rings are designed for use on shafts or in bores. The ring installs into a groove, thereby creating a shoulder to accurately position and retain other components of an assembly. The retaining shoulder is created when the ring attaches itself to the bore or shaft, typically by snapping into a groove.
Retaining Rings vs. Traditional Fasteners
The advantages of using retaining rings include their ease of assembly, low cost to manufacture, and accuracy of positioning when compared to traditional fasteners. Retaining rings only require a groove. This is an advantage over traditional fasteners that require threaded components, mating threaded holes, access holds, and counter-bores. Retaining rings function with a minimal amount of surface preparation to either the shaft or the housing.
