Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling connects two shafts with different bore sizes—35 mm and 1 1/4 in—in motion-control systems. It compensates for misalignment while transmitting torque, making it ideal for precision positioning, robotics, and servo-drive applications where zero backlash is required.

What are the specifications of the RULAND MANUFACTURING BCK50-35MM-1-1/4"-A?

This clamp-on bellows coupling has a 35 mm bore diameter 1 and a 1 1/4 in bore diameter 2, with a maximum speed of 10,000 RPM. It is made of stainless steel, features inch-to-metric bore dimensions, and is designed for keyed shafts. The manufacturer part number is BCK50-35MM-1-1/4"-A.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

3G Electric supplies RULAND MANUFACTURING bellows couplings worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the BCK50-35MM-1-1/4"-A or other RULAND MANUFACTURING shaft couplings.

How to install a clamp-on bellows coupling for keyed shafts?

To install, align the coupling halves over the keyed shafts, ensuring the key engages the keyway. Tighten the clamp screws evenly to the manufacturer's recommended torque using a torque wrench. Avoid over-tightening, which can damage the bellows. Verify shaft alignment within the coupling's rated misalignment limits.
