Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BCK50-24-20-A) is a clamp-on bellows shaft coupling for keyed shafts, featuring a 1 1/2 in bore diameter 1 and a 1 1/4 in bore diameter 2. It is constructed with a stainless steel bellows and an aluminum hub, and is designed for inch-sized shafts with different bore dimensions.

Frequently Asked Questions

What is the RULAND MANUFACTURING Bellows Coupling BCK50-24-20-A used for?

This clamp-on bellows coupling connects two keyed shafts with different bore diameters (1 1/2 in and 1 1/4 in) in motion-control applications. It compensates for misalignment while transmitting torque, commonly used in servo drives, encoders, and precision positioning systems.

What are the specifications of the RULAND MANUFACTURING BCK50-24-20-A?

The BCK50-24-20-A has a stainless steel bellows and aluminum hub, inch-sized bores of 1 1/2 in and 1 1/4 in, and a clamp-on design for keyed shafts. It is manufactured by RULAND MANUFACTURING and supports different bore dimensions.
