Product Description

This RULAND MANUFACTURING Bellows Coupling is a clamp-on bellows shaft coupling for keyed shafts with a 1 1/4 in bore diameter 1 and a 30 mm bore diameter 2, featuring same bore dimensions. It is made of stainless steel, has a maximum speed of 10,000 RPM, and is designed for inch to metric bore applications.

Frequently Asked Questions

What is the RULAND MANUFACTURING Bellows Coupling BCK36-1-1/4"-30MM-A used for?

This RULAND MANUFACTURING bellows coupling connects a 1 1/4 in keyed shaft to a 30 mm keyed shaft in motion-control systems. It compensates for angular, parallel, and axial misalignment while transmitting torque. Common applications include servo motors, encoders, and precision positioning equipment where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BCK36-1-1/4"-30MM-A bellows coupling?

This RULAND MANUFACTURING coupling has a 1 1/4 in bore diameter 1 and a 30 mm bore diameter 2, both with keyways. It is made of stainless steel, has a maximum speed of 10,000 RPM, and features a clamp-on design for inch to metric bore applications. The part number is BCK36-1-1/4"-30MM-A.

Where to buy the RULAND MANUFACTURING BCK36-1-1/4"-30MM-A bellows coupling worldwide?
