The Jaw couplings are offered in the industry's largest variety of stock bore/keyway combinations.

Main features
  • Fail-safe - will still perform if elastomer fails
  • No metal to metal contact 
  • Resistant to oil, dirt, sand, moisture and grease
  • More than 850,000 combinations of bore sizes 
  • Most types available from stock in 24 hours

These flexible couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications.
Applications include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers and conveyor belts. Jaw Type couplings are available in 24 sizes, from a minimum torque rating of 3.5 in-lbs (0.4 Nm) to a maximum torque rating of 170,004 in-lbs (19209 Nm), and a bore range of 0.125 inches (4.45 mm) to 7 inches (178 mm). Standard bore program covers DIN  bore/keyway combinations.

Jaw Type couplings generally consist of two hubs (available in sintered metal, aluminum, bronze, steel, stainless steel and ductile iron) and an elastomer element, known as a spider or cushion (materials available include NBR SOX rubber, Urethane, Hytrel® and Bronze).

L Type - Standard Jaw couplings
  • Industry's standard shaft coupling
  • Fail-safe (will still perform if elastometric "spider" fails)
  • Max Bore: 2.875 inches (73 mm)
  • Max Torque: 12,500 in-lbs (1412 Nm)

AL Type - Aluminum Jaw couplings
  • Lightweight aluminum version of the standard shaft coupling
  • Corrosion resistant (finished bores passivated for added protection)
  • Max bore: 1.875 inches (48 mm)
  • Max Torque: 2,268 in-lbs (256 Nm)

SS Type - Jaw stainless steel couplings
  • Stainless steel version of the industry standard shaft coupling
  • interchangeable with L and AL line of hubs (except AL150)
  • Max bore: 1.875 inches (48 mm)
  • Max Torque: 3,708 in-lbs inches (419 Nm)

SW Type - radially removable elastomer
  • Standard L Type coupling with radially removable elastomer
  • Fail-safe; plus open center allows a minimal shaft separation
  • 1,750 RPM limit (see Type LC for higher limit)
  • Max Bore: 2,625 inches (65mm)

RRS / RRSC Type - radially removable spacer coupling
  • Spacer coupling with "drop out" center for proper separation
  • Radially removable elastomers (easy installation and maintenance)
  • US and European industry standard pump/motor shaft separations
  • Spacer made of plastic, cast iron, or aluminum
