Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BCK26-12-8-A) is a clamp-on bellows shaft coupling for keyed shafts, featuring a 3/4 in bore diameter 1 and a 1/2 in bore diameter 2 with same bore dimensions. It is constructed from stainless steel, has a maximum speed of 10,000 RPM, and is designed for inch-sized shafts.

Frequently Asked Questions

What is the RULAND MANUFACTURING Bellows Coupling BCK26-12-8-A used for?

This clamp-on bellows shaft coupling connects two keyed shafts with 3/4 in and 1/2 in bores, compensating for misalignment in motion-control systems. It is commonly used in precision automation, robotics, and servo-drive applications where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BCK26-12-8-A?

The RULAND MANUFACTURING BCK26-12-8-A is a stainless steel bellows coupling with a 3/4 in bore diameter 1 and a 1/2 in bore diameter 2, both same bore dimensions. It has a maximum speed of 10,000 RPM and is designed for inch-sized keyed shafts. The coupling is clamp-on style.

How to select the correct RULAND MANUFACTURING bellows coupling for keyed shafts?

Select a coupling by matching bore diameters to your shaft sizes (here 3/4 in and 1/2 in), ensuring keyway dimensions align. Verify maximum speed (10,000 RPM) exceeds your application speed. Choose stainless steel for corrosion resistance. RULAND MANUFACTURING couplings offer zero backlash; confirm torque and misalignment ratings meet your system needs.
