Couplings

Our flexible shaft coupling products satisfy a wide variety of applications where precise positioning and control of machine components is required. We offer a broad line of standard designs with a variety of configurations to match your size and torque requirements.

Durability

Our stainless steel welded diaphragm couplings provide:

  • Low wind-up (rotational deflection between driver and load)
  • Low backlash (from reversing or varying loads)
  • Constant rotational velocity
  • Low inertia
  • High corrosion resistance
  • Ability to withstand extreme temperature conditions
  • Reliable axial and angular characteristics

Meeting Your Needs

Our standard bellows shaft couplings are available in bore sizes ranging from .090 to .625 inches [2.29 to 15.88 mm] with maximum torque ratings of 25 to 5000 in-oz [0.1 to 19.2 N•m].

If you don’t find a standard product that meets your application requirements, we can design a custom product for you.
