Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BC12-8MM-1/4"-A) is a clamp-on bellows shaft coupling for round shafts, made of stainless steel. It features an 8 mm bore diameter 1 and a 1/4 in bore diameter 2, with a maximum speed of 10,000 RPM. This coupling has same bore dimensions and is designed for inch to metric bore applications.

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This stainless steel clamp-on bellows coupling connects two round shafts with different bore sizes (8 mm and 1/4 in) while compensating for misalignment. It is used in precision motion control, servo systems, and encoders where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BC12-8MM-1/4"-A bellows coupling?

The RULAND MANUFACTURING BC12-8MM-1/4"-A is a stainless steel clamp-on bellows coupling with an 8 mm bore diameter 1 and a 1/4 in bore diameter 2. It has a maximum speed of 10,000 RPM and is designed for inch to metric bore applications with same bore dimensions.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING BC12-8MM-1/4"-A bellows coupling to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this precision coupling.

How to select a bellows coupling for inch to metric shaft sizes?

When selecting a bellows coupling like the RULAND MANUFACTURING BC12-8MM-1/4"-A, match each bore diameter to your shaft sizes (one metric, one inch). Ensure the coupling's torque rating and maximum speed (10,000 RPM) exceed your application requirements. Clamp-on style provides secure, zero-backlash grip.
