Disc Couplings


Quick Facts

  • Zero backlash, flexible shaft
  • Excellent response, high torque capacity
  • Identical clockwise and counterclockwise rotation
  • Plate springs absorb angular misalignment and shaft endplay
  • Single disc and double disc units available
  • Multiple bore and shaft configurations

Product Overview

Composed of two aluminum or steel hubs and stainless steel plate springs or disc packs. Disc couplings are available in single disc and double disc assemblies using one or two plate
springs. The plate springs transmit torque while accommodating misalignment. Disc couplings are commonly used for servo applications that require low-inertia, high torsional stiffness, and repeatable bi-directional characteristics.
