Beam couplings

Ruland Flexible beam couplings are machined from a single piece of aluminium or stainless steel and feature multiple helical cuts. The multiple cut design provides higher torque capabilities and greatly reduced wind-up when compared to commodity type single beam couplings.

Why choose a Ruland beam coupling?

  • Higher torsional rigidity compared to commodity style single-beam couplings.
  • Unique balanced clamp screw design reduces vibration while the cross cut increases clamping ability.
  • Machined from a single piece of aluminium or stainless steel with multiple spiral cuts for higher torsional stiffness and torque capabilities.
  • Accommodates parallel misalignment, angular misalignment and axial motion.
  • Two sets of cuts around centre member better accommodate parallel misalignment then single beam couplings.
  • Four beam and six beam couplings offered.  Four beam couplings are more flexible with lower bearing loads. Six beam couplings have increased torque capacity and higher torsional stiffness.
  • Aluminium couplings made from type 7075 aluminium for longer life.
  • Stainless steel couplings offered for greater torque capacity.
