Frequently Asked Questions

What is the RULAND MANUFACTURING BC50-20-20-A bellows coupling used for?

The RULAND MANUFACTURING BC50-20-20-A is a clamp-on bellows shaft coupling used to connect two round shafts of equal 1 1/4 in diameter in motion-control applications. It compensates for angular, parallel, and axial misalignment while transmitting torque. Common in precision automation, encoders, and servo systems, it provides zero-backlash performance.

What are the specifications of the RULAND MANUFACTURING BC50-20-20-A?

The BC50-20-20-A has a 1 1/4 in bore diameter on both ends (same bore dimensions), a stainless steel bellows, and an aluminum hub. It is an inch-sized, clamp-on design with no keyway. The manufacturer part number is BC50-20-20-A, and it is made by RULAND MANUFACTURING.

Where to buy the RULAND MANUFACTURING BC50-20-20-A worldwide?

3G Electric supplies the RULAND MANUFACTURING BC50-20-20-A bellows coupling worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this precision coupling to any country.

How to install the RULAND MANUFACTURING BC50-20-20-A clamp-on coupling?

To install the BC50-20-20-A, slide the coupling onto both shaft ends, ensuring the shafts are aligned within the bellows' misalignment limits. Tighten the clamp screws evenly to the torque specified by RULAND MANUFACTURING. Avoid over-tightening, which can damage the aluminum hub. No keyway alignment is needed.

Common applications for RULAND MANUFACTURING
Automated packaging machinery — Ruland beam couplings (e.g., PSR20-8-5-A) for connecting servo motors to conveyor drive shafts.
CNC machine tools — Ruland rigid couplings (e.g., CLX-4-4-A) for precise alignment of ball screw assemblies.
Robotic arm joints — Ruland Oldham coupling hubs (e.g., OSC16-6-A) for accommodating axial motion in end-effector drives.
Pump and compressor systems — Ruland stainless steel shaft collars (e.g., CL-3-ST) for securing impeller shafts.
Printing press rollers — Ruland clamp-on beam couplings (e.g., PCR18-8-8-A) for synchronizing roller rotation with minimal backlash.
Material handling conveyors — Ruland set screw couplings (e.g., PSMR29-7-7-A) for linking gearboxes to drive rollers.
