Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BC36-20-12-A) is a clamp-on bellows shaft coupling for round shafts, constructed from stainless steel. It features a 1 1/4 in bore diameter 1 and a 3/4 in bore diameter 2, with same bore dimensions, and a maximum speed of 10,000 RPM. This inch-series coupling is designed for applications requiring zero backlash and high torsional stiffness.

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

A RULAND MANUFACTURING bellows coupling is used in precision motion control applications requiring zero backlash and high torsional stiffness. It connects two rotating shafts while accommodating misalignment, making it ideal for servo motors, encoders, and linear actuators in industrial automation and robotics.

What are the specifications of the RULAND MANUFACTURING BC36-20-12-A bellows coupling?

The RULAND MANUFACTURING BC36-20-12-A bellows coupling has a 1 1/4 in bore diameter 1 and a 3/4 in bore diameter 2, with same bore dimensions. It is made of stainless steel, has a maximum speed of 10,000 RPM, and is an inch-series clamp-on design for round shafts.
