Frequently Asked Questions
What is a RULAND MANUFACTURING clamp-on bellows shaft coupling used for?
This coupling connects two round shafts with different bore diameters (5/8 in and 1/2 in) in motion control applications. It compensates for misalignment while transmitting torque smoothly, commonly used in servo motors, encoders, and precision positioning systems where zero backlash is required.
What are the specifications of the RULAND MANUFACTURING BC21-10-8-A coupling?
The BC21-10-8-A has a 5/8 in bore diameter 1 and a 1/2 in bore diameter 2, with a stainless steel bellows and aluminum body. It is designed for inch-sized round shafts with different bore dimensions and features a clamp-on style for secure attachment.
