Single Angle Contracting Collet

The Single Angle Contracting Arbor was developed to locate a gear or pinion by contracting on one OD shank and pulling the part back against a seating surface to locate the part.


  • Accuracy and repeatability of 0.005 mm (0.0002") T.I.R.
  • Contraction of up to 0.45 mm (0.018") for a long wear life
  • Shank tolerance of 0.127 mm (0.005") or less is allowed
  • Torque holding capacity able to handle any gear process
  • Internal collet safety to protect the collet from damage if the arbor is activated without a part in place
  • Part pull back to insure positive seating of the part against the seating surface
  • Compatible with auto loader
  • No shank size limitations for the part to be held unless the process causes interference with the arbor

Optional features:

  • Air blank seating (with properly equipped machine)
  • Quick change
  • Replaceable wear collar for ease of repair (for lapping and testing only)
  • Pin backing when the process does not allow backing behind the pinion head
