Beam Couplings

Quick Facts

  • One-piece metallic beam coupling
  • Zero backlash, flexible shaft
  • Spiral and parallel cut designs available
  • Accommodates misalignment and shaft endplay
  • Identical clockwise and counterclockwise rotation
  • Available in aluminum or stainless steel
  • Multiple bore and shaft connecting configurations

Product Overview

A single-piece aluminum or stainless steel element with spiral or parallel cuts designed to handle misalignment while transmitting torque in a low-inertia design. Beam couplings are commonly used in low torque applications that do not require high torsional stiffness or excessive operating speeds.
