Rigid coupling
max. 2 - 19.2 Nm | Types RS, RC, & RT
OEP Couplings
Includes:
Type RS (set screw)
Type RC (one-piece clamping)
Type RT (three-piece clamping)
Rigid shaft couplings are generally used when there is little or no shaft misalignment, and any misalignment resulting from thermal growth during operation will result in small enough reactive forces that the support bearings won't be adversely affected.
Rigid couplings are simple, robust, and economical, and their torque is limited only by the clamping force between coupling and shaft. They have low moment of inertia, and the two shafts maintain constant angular position.
OEP Couplings' type RS (set screw), type RC (one-piece clamping), and type RT (three-piece clamping) rigid couplings are all machined from bar on state-of-the-art CNC machining centers with live tooling. As a result, very close tolerances can be held, and this is a critical and all-too-often overlooked factor in rigid couplings. If for example, the two bores are out of alignment with one another, the impact on other components within the assembly can be catastrophic. These couplings are machined form high-strength alloys such as 7075 aluminum and 17-4 stainless steel.
