Product Description

The RULAND MANUFACTURING BCK36-1-1/4"-25MM-A is a clamp-on bellows shaft coupling for keyed shafts, constructed from stainless steel. It features a 1 1/4 in bore diameter on one side and a 25 mm bore diameter on the other, with same bore dimensions, and a maximum speed of 10,000 RPM. This coupling is designed for inch to metric bore applications.

Frequently Asked Questions

What is the RULAND MANUFACTURING BCK36-1-1/4"-25MM-A bellows coupling used for?

This clamp-on bellows shaft coupling is used to connect keyed shafts in motion control and power transmission applications, accommodating inch to metric bore sizes. It is suitable for precision positioning systems, encoders, and servo drives where misalignment compensation and torsional rigidity are required.

What are the specifications of the RULAND MANUFACTURING BCK36-1-1/4"-25MM-A?

The BCK36-1-1/4"-25MM-A is a stainless steel bellows coupling with a 1 1/4 in bore diameter on one side and a 25 mm bore diameter on the other, both keyed. It has a maximum speed of 10,000 RPM and is designed for inch to metric bore applications with same bore dimensions.
