Request Information
  • High torque capacity
  • High fatigue resistance
  • Corrosion resistant steel (CRES)
The H Series coupling is ideal when high strength, excellent fatigue resistance and high torsional stiff ness is called for in your application. The H Series' premium performance capability is designed for applications requiring a heavy-duty coupling, such as drive systems, small pumps and gear boxes.

  • No maintenance
  • Shaft sizes from 3/32 to 3/4
An array of options, in a variety of diameter sizes, allows you to tailor the A or H Series to your specific applications. A and H Series options include set screw or integral clamp attachments and inch or metric bores.
