Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

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

What are the specifications of the RULAND MANUFACTURING BCK50-28-28-A bellows coupling?

The BCK50-28-28-A has a 1 3/4 in bore diameter on both ends (same bore dimensions), a stainless steel bellows, and an aluminum hub. It is a clamp-on, non-keyed design for inch-sized shafts. The coupling is manufactured by RULAND MANUFACTURING and is suitable for keyed shafts.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

You can source the RULAND MANUFACTURING BCK50-28-28-A bellows coupling through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

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

To install, clean the shaft ends and coupling bores. Loosen the clamp screws, slide the coupling onto both shafts, and align the equipment. Tighten the screws evenly to the torque specified by RULAND MANUFACTURING. Verify alignment with a dial indicator to avoid overloading the bellows.
