Shaft Collar and Coupling Basics

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.

 
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.

 
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”
