Product Description

Frequently Asked Questions

What is a Ruland MBC51-20-17-A bellows coupling used for?

The Ruland MBC51-20-17-A clamp-on bellows coupling connects two shafts with different diameters (20 mm and 17 mm) in motion control applications. It compensates for misalignment while transmitting torque smoothly, making it ideal for precision positioning systems, encoders, and servo drives.

What are the specifications of the Ruland MBC51-20-17-A coupling?

The Ruland MBC51-20-17-A has a 20 mm bore diameter 1 and a 17 mm bore diameter 2. It features a stainless steel bellows and an aluminum hub, with a clamp-on design for metric shafts. The part number is MBC51-20-17-A, and it accommodates different bore dimensions.

Where to buy a Ruland MBC51-20-17-A coupling worldwide?

3G Electric supplies the Ruland MBC51-20-17-A bellows coupling to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this motion control coupling.

How to install a Ruland clamp-on bellows coupling?

To install the Ruland MBC51-20-17-A, clean both shaft ends and slide the coupling onto the 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 to avoid premature wear.

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.
