Frequently Asked Questions

What is the RULAND MANUFACTURING BC12-5-4-A coupling used for?

The RULAND MANUFACTURING BC12-5-4-A is a clamp-on bellows shaft coupling designed for motion control applications. It connects two round shafts with different bore diameters (5/16 in and 1/4 in) while compensating for misalignment. Typical uses include precision positioning systems, encoders, and servo drives where zero backlash and torsional rigidity are required.

What are the specifications of the RULAND MANUFACTURING BC12-5-4-A?

The BC12-5-4-A is an inch-series clamp-on bellows coupling with a 5/16 in bore on one end and a 1/4 in bore on the other. It features a stainless steel bellows and an aluminum hub. The coupling accommodates different bore dimensions and is designed for motion control. The manufacturer part number is BC12-5-4-A.

Where to buy the RULAND MANUFACTURING BC12-5-4-A worldwide?
