description

  • Functions like an HO ring in a housing/bore, only the lugs are “reversed.” This version reduces the distance the lugs of the standard HO extend into the inner circumference of the housing/bore and allows for another assembly to pass through unimpeded.

features

  • Axially assembled
  • Axially installed into machined grooves in housings/bores (internal) or on shafts (external)
  • Have lug holes for ease of installation/removal
  • Make uniform contact when released in a groove
  • Can accommodate higher thrust loadings
  • Provide more of a shoulder with which to retain a component or assembly than constant section or spiral retaining rings
