Retaining Rings

Internal Retaining Ring, Axially Assembled Internal Retaining Ring, Standard Internal Retaining Ring, Tapered Section Internal Retaining Ring

Definition:
Internal retaining rings are designed to hold components or assemblies on a shaft, or inside a housing. An internal retaining ring is installed in a machined groove that leaves a portion of the retaining ring exposed to act as a shoulder to hold the component or assembly in place. Axially assembled internal retaining rings are installed horizontally along the center point of an axis. To ensure contact with the grooved housing along its entire periphery (ensuring high thrust load capacity), ensuring high thrust load capacity, a tapered section internal retaining ring decreases symmetrically from the center to the free ends, remaining circular when contracted or expanded within the limits of normal use.

Internal Retaining Rings are available in the following materials and finishes:

  • Spring Steel: Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Pickling, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II
  • Stainless Steel 15PH-7MO: Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Passivate, Pickling, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II

E-Style Retaining Ring, Radially Assembled E-Style Retaining Ring, Standard E-Style Retaining Ring, Tapered Section E-Style Retaining Ring

Definition:
E-style retaining rings are designed to hold components or assemblies onto a shaft, or inside a housing. An e-style retaining ring is radially assembled or installed externally into machined grooves on a shaft. It requires a deeper groove for the three prongs to make contact and provide exceptional thrust load capacity to hold the component or assembly in place. A tapered section e-style retaining ring decreases symmetrically from the center to the free ends, remaining circular when contracted or expanded within the limits of normal use.

E-style Retaining Rings are available in the following materials and finishes:

  • Spring Steel: Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Pickling, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II
  • Stainless Steel 15PH-7MO: Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Passivate, Pickling, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II
