Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING BC36-20-20-A bellows coupling used for?

The RULAND MANUFACTURING BC36-20-20-A is a clamp-on bellows shaft coupling used to connect two round shafts with 1 1/4 in bore diameters in motion-control applications. Its stainless steel bellows compensates for misalignment while transmitting torque, making it suitable for precision positioning systems, encoders, and servo drives.

What are the specifications of the RULAND MANUFACTURING BC36-20-20-A bellows coupling?

The RULAND MANUFACTURING BC36-20-20-A bellows coupling has a 1 1/4 in bore diameter on both ends, a stainless steel bellows, and an aluminum hub. It is a clamp-on type for inch-dimension shafts with different bore dimensions. The manufacturer part number is BC36-20-20-A.

Where to buy the RULAND MANUFACTURING BC36-20-20-A bellows coupling worldwide?

You can source the RULAND MANUFACTURING BC36-20-20-A bellows coupling worldwide through 3G Electric. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

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

To install the RULAND MANUFACTURING BC36-20-20-A, clean both shaft ends and the coupling bores. Slide the coupling onto the shafts, align the equipment, then tighten the clamp screws evenly to the manufacturer's recommended torque. Avoid over-tightening to prevent damage to the bellows or shafts.
