Flanged Stubshaft Adaptor

Stub shaft adaptors for use with SO and SX sprag clutches providing a mounting stub shaft for mechanical elements such as chainwheels, couplings, gears, pulleys, cams, levers, etc, when the size or configuration of these parts does not allow bolting holes to be drilled to match the existing tapped holes in the clutch.


  • Extended stub shaft used to fit couplings, chain pinions, gears, cams and index lever arms to standard sprag clutches giving extra design flexibility
  • Can reduce the overall dimensions of the combination drive package, thus allowing a more compact size.
