Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BC12-5MM-3/16"-A) is a clamp-on bellows shaft coupling for round shafts, constructed from stainless steel. It features a 5 mm bore diameter 1 and a 3/16 in bore diameter 2, with a maximum speed of 10,000 RPM. This coupling has an inch to metric bore configuration with same bore dimensions.

Frequently Asked Questions

What is the RULAND MANUFACTURING BC12-5MM-3/16"-A bellows coupling used for?

This clamp-on bellows shaft coupling connects two rotating shafts in motion-control applications such as encoders, stepper motors, and servo drives. It compensates for angular, parallel, and axial misalignment while transmitting torque smoothly. The stainless steel construction suits industrial environments requiring corrosion resistance and precision positioning.

What are the specifications of the RULAND MANUFACTURING BC12-5MM-3/16"-A bellows coupling?

This coupling has a 5 mm bore diameter 1 and a 3/16 in bore diameter 2, with a maximum speed of 10,000 RPM. It is made of stainless steel, features an inch-to-metric bore configuration with same bore dimensions, and is a clamp-on type for round shafts. The manufacturer part number is BC12-5MM-3/16"-A.

Where to buy the RULAND MANUFACTURING BC12-5MM-3/16"-A bellows coupling worldwide?
