Frequently Asked Questions

What is the RULAND MANUFACTURING BC21-5/8"-12MM-A bellows coupling used for?

This clamp-on bellows shaft coupling connects two round shafts with different bore sizes—5/8 in and 12 mm—in inch-to-metric applications. It is used in precision motion control, servo systems, and encoders where misalignment compensation and torsional rigidity are required.

What are the specifications of the RULAND MANUFACTURING BC21-5/8"-12MM-A?

The BC21-5/8"-12MM-A is a stainless steel bellows coupling with a 5/8 in bore diameter 1 and a 12 mm bore diameter 2, both same bore dimensions. It has a maximum speed of 10,000 RPM and is designed for inch-to-metric bore applications. The part number is BC21-5/8"-12MM-A.

Where to buy the RULAND MANUFACTURING BC21-5/8"-12MM-A worldwide?

3G Electric supplies the RULAND MANUFACTURING BC21-5/8"-12MM-A bellows coupling worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct RULAND MANUFACTURING bellows coupling for inch-to-metric shafts?

To select the correct coupling, match bore diameters to your shaft sizes—one inch (5/8 in) and one metric (12 mm). Ensure the coupling's maximum speed (10,000 RPM) exceeds your application's operating speed. RULAND MANUFACTURING offers stainless steel construction for corrosion resistance.
