Miniature bellows couplings
When installation space is limited but positioning accuracy cannot be compromised, R+W Miniature Couplings provide an ideal solution. Featuring a precision-engineered stainless steel bellows, these compact couplings deliver exceptional torsional stiffness and completely zero-backlash torque transmission, making them perfect for demanding motion control applications.
The stainless steel bellows compensates for radial, axial and angular shaft misalignment with very low restoring forces, protecting connected components while maintaining highly accurate motion. Designed specifically for low torque applications from 0.05 to 10 Nm, these couplings can operate at speeds of up to 200,000 rpm, depending on the model. Their lightweight construction and excellent dynamic characteristics make them particularly suitable for high-speed precision systems.
As the official Hungarian partner, BIBUS Kft. provides engineering support to help select the most suitable miniature coupling based on available installation space, torque requirements, operating speed and positioning accuracy.
