Frequently Asked Questions

What is a RULAND MANUFACTURING Bellows Coupling used for?

This clamp-on bellows shaft coupling connects two keyed shafts with different bore diameters (1 1/4 in and 1 in) in motion-control systems. It compensates for misalignment while transmitting torque, commonly used in servo motors, encoders, and precision positioning equipment.

What are the specifications of the RULAND MANUFACTURING Bellows Coupling BCK50-20-16-A?

The BCK50-20-16-A has bore diameters of 1 1/4 in and 1 in, a max speed of 10,000 RPM, and is made of stainless steel. It is a clamp-on design for keyed shafts with different bore dimensions, inch-sized, and manufactured by RULAND MANUFACTURING.
