Servo-Beam™ Couplings

The patented Servo-Beam™ motor couplings are the best replacement for expensive and delicate bellows couplings. The Servo-Beamcoupling is a true servo coupling exhibiting torsional rigidity, zero backlash, high RPM capability and superior life.

Ondrives.US Metal Servo-Beam™ shaft couplers are constructed with 420 stainless steel flexible beams and 416 stainless steel or aluminum hubs. They can operate at up to 10,000 rpm, up to 7 degrees angular compensation and with torques up to 300 in-lbs.

Polymer Servo-Beam™ couplings have flexible beams of an engineered polymer and aluminum hubs. Servo shaft couplers can handle speeds up to 10,000 rpm and torques up to 200 in-lbs.

Customization is available on these flexible servo couplings. Please contact our application engineers to discuss your particular needs.

Ondrives.US engineers have developed a White Paper “How to select Shaft Couplings” to assist you in the selection of the most appropriate shaft to shaft coupling for your application.

Couple to almost any shaft diameter with Ondrives.US Bore Reducers.

Attach your servo motor shaft coupling to an Ondrives.US Precision Ground Shaft, available from stock.
