Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

A RULAND MANUFACTURING bellows coupling like the BCK26-8-6-A is used to connect two rotating shafts while compensating for misalignment. It is ideal for precision motion control applications in packaging, robotics, and machine tools where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BCK26-8-6-A bellows coupling?

The RULAND MANUFACTURING BCK26-8-6-A is a stainless steel clamp-on bellows coupling for keyed shafts. It has a 1/2 in bore diameter 1 and a 3/8 in bore diameter 2, a maximum speed of 10,000 RPM, and inch-sized same bore dimensions. It is designed for precision shaft alignment.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING BCK26-8-6-A bellows coupling worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this precision stainless steel coupling.

How to install a RULAND MANUFACTURING clamp-on bellows coupling?

To install a RULAND MANUFACTURING clamp-on bellows coupling, ensure shafts are clean and aligned within the coupling's misalignment ratings. Slide the coupling onto both shafts, tighten the clamp screws evenly to the manufacturer's torque specification, and verify runout with a dial indicator before operation.
