Product Description

The RULAND MANUFACTURING BC21-10-6-A is a clamp-on bellows shaft coupling for round shafts, featuring a 5/8 in bore diameter on one side and a 3/8 in bore diameter on the other. It is constructed with a stainless steel bellows and an aluminum hub, designed for inch-sized shafts. This motion control coupling accommodates different bore dimensions and includes a clamp-on attachment.

Frequently Asked Questions

What is the RULAND MANUFACTURING BC21-10-6-A motion control coupling used for?

The RULAND MANUFACTURING BC21-10-6-A is a clamp-on bellows shaft coupling used to connect two round shafts of different diameters—5/8 in and 3/8 in—in motion control applications. It compensates for misalignment while transmitting torque smoothly, making it suitable for precision positioning systems, encoders, and servo drives.

What are the specifications of the RULAND MANUFACTURING BC21-10-6-A coupling?

The BC21-10-6-A has a 5/8 in bore diameter on one side and a 3/8 in bore diameter on the other. It features a stainless steel bellows and an aluminum hub, with inch-sized bores and a clamp-on attachment. The coupling accommodates different bore dimensions and is manufactured by RULAND MANUFACTURING.

Where to buy the RULAND MANUFACTURING BC21-10-6-A coupling worldwide?
