Rigid Couplings

Ruland’s rigid couplings are available in one- and two-piece clamp designs, and set screw style, with and without keyways in a variety of materials. A large number of standard sizes are available to fit shafts from 1/8" to 2" in the inch series and 3mm to 50mm in the metric series. Rigid couplings are stamped with the Ruland name and the bore sizes for easy identification.

Clamp style rigid couplings wrap around the shaft, providing high torsional holding power without the shaft damage and fretting that occurs when set screw style couplings are used. Two-piece clamp styles also allow for disassembly and maintenance without removal of other machine components and feature opposing hardware for a balanced design.

We take extra steps in the manufacture of rigid couplings to provide important performance benefits. For example, the bores of Ruland straight-bore couplings are precision honed. Honing ensures the bores are concentric and also corrects any residual distortions caused by stresses introduced during the manufacturing process. This results in a round, precisely sized bore yielding easier installation and greater torque transmission capability.

Clamp style rigid couplings are supplied with Ruland’s Nypatch® socket head cap screws. Nypatch® involves a process of depositing a 360° ring of nylon on several threads of the screws. This coating reduces screw vibration, which can cause the screws to loosen and torque transmission ability to diminish during the course of normal use.

Rigid couplings are suitable for applications when misalignment is neither present nor desired, including connecting line-shafting and attaching a motor to a gearbox. They are increasingly being used in precision motion control applications with properly aligned components.
