The addition of keyways allows for increased torque capacity and prevents the coupling from slipping on the shaft when over torqued.375",OD 1.625",L 2. Ruland standard length bellows couplings are a high torque zero-backlash coupling commonly found in responsive systems on semiconductor, solar, test and measurement, and printing equipment.
8750" bores, a 1.These components are manufactured to tight tolerances using proprietary processes that ensure smooth operation and high misalignment accommodation up to 45°, which is a significant improvement over commodity style single universal joints.
