R+W couplings: essential to drive technology

R+W drive components are an essential part of just about any high performance machine - from the latest high tech medical devices to wind turbines and drilling platforms to space systems. Couplings are used wherever rotation and torque need to be transmitted between two machine components. The requirements placed on couplings differ greatly along the lines of their areas of application.

Aside from reliable torque transmission, their most important tasks include providing protection against damage from shaft misalignment, vibration and torque overload. For high performance machinery to run with speed, accuracy and efficiency, torque transmission needs to be fast, precise and reliable. To this end, R+W can perfectly tailor critical performance characteristics of its couplings, such as damping, torsional stiffness, balancing, and moment inertia.

A wide range of couplings for all requirements

Coupling selection is always dependent on the application and its unique requirements. R+W offers various coupling models for both high precision and heavy industrial machinery types.

Precision couplings transmit torques ranging from 0.05 to 25,000 Nm, depending on the coupling type and size. R+W's product range includes torsionally rigid metal bellows and miniature bellows couplings, vibration damping elastomer couplings, torque limiting safety couplings, connecting shafts, and servo disc pack couplings in a wide variety of sizes and configurations.

Industrial series couplings transmit torques ranging from 200 to 2,080,000 Nm. Here R+W offers heavy duty safety couplings, torsionally rigid disc pack couplings and flexible gear couplings, along with larger sizes of metal bellows couplings and elastomer couplings.

No matter how widely the challenges for a coupling and its function may vary - R+W is the pioneer in coupling technology and provides solutions for all industries.

Always the right choice: couplings from R+W

Whether for high precision or heavy industry, couplings from R+W work dynamically, precisely and with zero backlash. They help to keep friction to a minimum, and many are wear and maintenance free, with no moving parts - thus guaranteeing an extremely long service and performance life. Through its wide product portfolio and innovative coupling technology, R+W is ready to meet your torque transmission challenges.
