Frequently Asked Questions
What is the RULAND MANUFACTURING Bellows Coupling BCK21-1/2"-8MM-A used for?
This clamp-on bellows shaft coupling connects a 1/2 in keyed shaft to an 8 mm keyed shaft in motion-control systems. It compensates for misalignment while transmitting torque, making it suitable for precision positioning, robotics, and servo-drive applications where zero backlash and high torsional stiffness are required.
What are the specifications of the RULAND MANUFACTURING Bellows Coupling BCK21-1/2"-8MM-A?
This coupling has a 1/2 in bore diameter and an 8 mm bore diameter, both with keyways. It is made of stainless steel, has a maximum speed of 10,000 RPM, and features an inch-to-metric bore configuration with same bore dimensions. The manufacturer part number is BCK21-1/2"-8MM-A.
