RULAND MANUFACTURING Bellows Coupling: 1 3/4 in Bore Dia 1, 1 1/4 in Bore Dia 2, Aluminum

This clamp-on bellows shaft coupling connects two round shafts with different bore diameters (1 3/4 in and 1 1/4 in) in motion-control applications. It compensates for angular, parallel, and axial misalignment while transmitting torque. Common uses include servo motors, encoders, and precision positioning systems where zero backlash is required.

The BC50-28-20-A is a clamp-on bellows coupling with a stainless steel bellows and aluminum body. It has bore diameters of 1 3/4 in and 1 1/4 in, designed for inch-sized shafts with different bore dimensions. The coupling is manufactured by RULAND MANUFACTURING and is suitable for applications requiring misalignment compensation.

To install, clean both shaft ends and the coupling bores. Loosen the clamp screws, slide the coupling onto the shafts, and align the equipment. Tighten the screws evenly to the manufacturer's recommended torque using a torque wrench. Avoid over-tightening to prevent damage to the bellows. Verify alignment with a dial indicator before final tightening.
