Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BCK21-10-6-A) is a clamp-on bellows shaft coupling for keyed shafts, featuring a 5/8 in bore diameter 1 and a 3/8 in bore diameter 2. It is constructed from stainless steel, has a maximum speed of 10,000 RPM, and is designed for inch-sized shafts with same bore dimensions.

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

A RULAND MANUFACTURING bellows coupling, like the BCK21-10-6-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 BCK21-10-6-A bellows coupling?

The RULAND MANUFACTURING BCK21-10-6-A bellows coupling has a 5/8 in bore diameter 1 and a 3/8 in bore diameter 2, a maximum speed of 10,000 RPM, and is made of stainless steel. It is a clamp-on type for keyed shafts with same bore dimensions, designed for inch-sized shafts.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

3G Electric supplies RULAND MANUFACTURING bellows couplings like the BCK21-10-6-A to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for a quote and lead time on this precision coupling.

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

To install a RULAND MANUFACTURING clamp-on bellows coupling, clean both shaft ends and the coupling bores. Slide the coupling onto the shafts, align the keyways, and tighten the clamp screws evenly to the manufacturer's recommended torque. Ensure shafts are properly aligned to avoid premature wear.
