Frequently Asked Questions

What is a RULAND MANUFACTURING clamp-on bellows shaft coupling used for?

This coupling is used in motion control applications requiring precise shaft alignment. It connects two 1/2 in round shafts with a stainless steel bellows design that compensates for misalignment while transmitting torque. Common in servo systems, encoders, and linear actuators.

What are the specifications of the RULAND MANUFACTURING BC21-8-8-A coupling?

The BC21-8-8-A has a 1/2 in bore diameter on both ends (same bore dimensions), is made of stainless steel, uses inch dimensions, and is a clamp-on bellows shaft coupling. It is manufactured by RULAND MANUFACTURING and designed for motion control applications.

Where to buy RULAND MANUFACTURING couplings in worldwide?

3G Electric supplies RULAND MANUFACTURING motion control couplings worldwide. As a global industrial solutions provider, we handle logistics, customs, and delivery to your location. Contact us to source the BC21-8-8-A or other RULAND MANUFACTURING couplings for your application.

How to install a RULAND MANUFACTURING clamp-on bellows coupling?

Clean shafts and bore surfaces, then slide the coupling onto both shafts. Tighten the clamp screws evenly to the manufacturer's recommended torque using a torque wrench. Ensure shafts are aligned within the coupling's misalignment ratings. Do not exceed axial or angular limits to avoid damaging the bellows.
