Bellows Couplings
R+W specializes in crafting precision couplings tailored to meet the rigorous demands of high-performance motion systems. These couplings are engineered to withstand dynamic motion, varying drive torque, and safeguard system components from vibration and overload. With the growing emphasis on compact, energy-efficient drive components, these precision couplings offer exceptional torque density, making them well-suited for compact machinery. R+W offers a range of products, from off-the-shelf standard options to fully customized units. Working closely with clients from the initial stages to delivery, our couplings ensure precise, backlash-free motion transmission.
Precision couplings mainly fall into three categories: Metal Bellows Couplings, Elastomer Couplings, and Torque Limiters.
Metal Bellows Couplings feature a torque range from 0.05 to 100,000 Nm. They offer torsional rigidity along with flexibility, providing stability and adaptability in motion transfer.
Elastomer Couplings, with a torque range from 0.05 to 25,000 Nm, are designed for vibration dampening, effectively reducing vibrations within the system.
Torque Limiters cover a torque range from 0.1 to 2,800 Nm. They operate without backlash, ensuring precise load cut-off and offering exact control while protecting against overloads.
