- 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.
