Evolution & Innovation

Shaft Collars

Historically, the primary function of a shaft collar was to retain its position on a shaft, and act as a stop or locator.

Largely through innovations by Stafford, shaft collars have taken on the jobs of:

  • Securing split hubs of other components
  • Acting as integral clamps for gears and sprockets
  • Actuating sensors in both rotary and linear motion
  • Transmitting torque to (attached), rotating components
  • Attaching components to shafts and tube (round, square & hex)
  • Providing micrometer linear adjustments to other shaft components
  • Acting as adjustable spring tensioners
  • And many others

Set-Screw Type Collars and Couplings

  • Were the only commercially available products up to the 1960’s.
  • They are simple and effective in many applications, but not at all appropriate in many more.
  • They don’t hold well on hardened shafts and can badly mar non-hardened shafts.

Stafford Clamp-Type Collars and Couplings:

  • Do not mar expensive shafts.
  • Are suitable for use on tubing.
  • Are also available with threaded, hex and square bores.
  • Signature and Solution lines are “100% Made in America”

Clamp-Type Collars and Rigid Couplings

  • Became available as a premium product in the mid 1960’s and soon became accepted as a preferred alternative
  • Eventually the mainstream solution to all but the most rudimentary applications.

Only Stafford also features:

  • Accu-Clamp
  • Accu-Flange
  • Python
  • Again, these and other innovative products are all “100% Made in America”

Stafford’s experience goes back to the beginning, and we’ve been innovating ever since.
