RULAND® offers five types of zero-backlash flexible couplings, designed to transmit torque without torsional play while compensating for misalignment.

Beam couplings are available in three series—P-Series, F-Series, and MW-Series—and feature multiple helical cuts that allow them to accommodate parallel, angular, and axial misalignments. These couplings are ideal for applications ranging from light-duty uses to precision devices like encoders and tachometers.

Bellows couplings provide excellent torsional stiffness combined with superior misalignment compensation. Their design makes them perfect for high-precision and high-speed applications where reliability is critical.

Oldham couplings are especially suited for handling parallel misalignment with ease. They offer the advantage of easy maintenance since their center disc can be replaced without removing the entire coupling.

Miniature disc couplings are designed for tight spaces and precision applications such as instrumentation and medical devices. Their compact and backlash-free design ensures accurate and reliable performance even in confined areas.

Curved jaw couplings provide good flexibility and vibration damping, making them a solid choice for medium torque applications including stepper motors and other motion control systems.
