Replace Bellows Couplings with Equal Performance at Half the Cost

Ondrives.US’ LCSP and LCGP Servo-Beam™ couplings provide the same performance and flexibility of high RPM bellows couplings at roughly half the price. Make the switch today!

Servo-Beam™ couplings deliver zero backlashes, high RPM performance, and reliable performance over a long working life. They are true servo couplings and are rated for speeds as high as 10,000 RPMs. They can operate at up to 7° of angular compensation and with up to 200 in-lbs. of torque.

These high RPM polymer flexible couplings are manufactured with 6061 aluminum hubs and engineered polymer flex beams.
