  • Note: For dynamic torque rating, static torque rating should be divided by 2 for nonreversing, and by 4 for reversing applications.

Flexible 4-Beam Couplings
  • Flexible couplings offer high torsional stiffness and shock absorption. Machined from a single piece of 7075 aluminum. Connect delicate components such as encoders and tachometers. Small bearings make low radial forces.
  • Zero backlash multiple cut design Max. rpm: 6000 Max. angular misalignment: 3 Max. temp.: 225 F (107 C) Bright finish
