Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

A RULAND MANUFACTURING bellows coupling is used to connect two shafts in motion-control applications, compensating for misalignment while transmitting torque. It is ideal for precision positioning systems, encoders, and servo drives where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BCK21-1/2"-12MM-A?

The BCK21-1/2"-12MM-A is a stainless steel clamp-on bellows coupling for keyed shafts. It has a 1/2 in bore diameter 1 and a 12 mm bore diameter 2 with same bore dimensions. Maximum speed is 10,000 RPM. It is designed for inch to metric bore applications.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

You can source RULAND MANUFACTURING bellows couplings worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select a RULAND MANUFACTURING bellows coupling for a keyed shaft?

To select a RULAND MANUFACTURING bellows coupling, match the bore diameters to your shaft sizes (inch and metric), confirm the keyway dimensions, and ensure the maximum speed rating (e.g., 10,000 RPM) exceeds your application speed. Verify torque requirements and misalignment tolerance for reliable performance.
