Frequently Asked Questions

What is the RULAND MANUFACTURING BCK36-20-12-A bellows coupling used for?

The RULAND MANUFACTURING BCK36-20-12-A is a clamp-on bellows shaft coupling designed for keyed shafts in motion-control applications. It compensates for angular, parallel, and axial misalignment while transmitting torque in precision equipment such as encoders, stepper motors, and servo drives.

What are the specifications of the RULAND MANUFACTURING BCK36-20-12-A?

The BCK36-20-12-A has a 1 1/4 in bore diameter 1 and a 3/4 in bore diameter 2, with same bore dimensions. It is made of stainless steel, has a maximum speed of 10,000 RPM, and is designed for inch-sized keyed shafts. The manufacturer part number is BCK36-20-12-A.

Where to buy the RULAND MANUFACTURING BCK36-20-12-A worldwide?

You can source the RULAND MANUFACTURING BCK36-20-12-A through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the coupling reaches your facility reliably.

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

To install the BCK36-20-12-A, clean the shaft ends and keyways, then slide the coupling onto both shafts. Tighten the clamp screws evenly to the manufacturer's recommended torque using a torque wrench. Ensure shafts are aligned within the coupling's misalignment ratings to avoid premature wear.
