R+W Coupling Technology

Precision Couplings and Line Shafts

R+W Coupling Technology is an ISO 9001 certified manufacturer of precision couplings, torque limiters, and line shafts for demanding motion control and power transmission applications. With a philosophy of meeting specific customer requirements from conception to production, R+W has supplied many thousands of custom coupling designs, creating a wealth of knowledge about the technical requirements associated with a wide variety of industries and applications.

Over the past 20+ years this has resulted in a position of market leadership for torsion resistant flexible bellows couplings. Many elastomer coupling models ship from stock, and include the benefit of a proprietary calibration process to ensure smooth running. All couplings and torque limiters are designed to operate free of wear and backlash, and help to ensure efficient and safe operation of rotating equipment.
