Product Description

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING MBC57-30-20-A clamp-on bellows coupling connects two round shafts with 30 mm and 20 mm bores. It compensates for misalignment while transmitting torque smoothly, ideal for precision motion-control applications in packaging, robotics, and machine tools.

What are the specifications of the RULAND MANUFACTURING MBC57-30-20-A?

The MBC57-30-20-A is a stainless steel bellows coupling with metric same bore dimensions. It has a 30 mm bore diameter 1, a 20 mm bore diameter 2, and a maximum speed of 10,000 RPM. The clamp-on design secures directly to round shafts without keyways.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING MBC57-30-20-A bellows coupling to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact our team for a quote and lead time on this stainless steel metric coupling.

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

Slide the coupling over both shaft ends, align the bores, then tighten the clamp screws evenly with a torque wrench to the manufacturer’s recommended value. Ensure shafts are clean and free of burrs. Avoid over-tightening to prevent damage to the bellows element.

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.
