Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

A RULAND MANUFACTURING bellows coupling is used to connect two shafts while compensating for misalignment in precision motion control applications. It is ideal for servo motors, encoders, and linear actuators where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING MBCK41-20-20-A?

The RULAND MANUFACTURING MBCK41-20-20-A is a clamp-on bellows shaft coupling for keyed shafts. It has a 20 mm bore diameter 1 and a 20 mm bore diameter 2 with a 6 mm x 6 mm keyway size 1. It is made of stainless steel and designed for metric shaft sizes.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

You can source RULAND MANUFACTURING bellows couplings worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times.

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

To install a RULAND MANUFACTURING clamp-on bellows coupling, clean the shaft ends and keyways, then slide the coupling onto both shafts. Tighten the clamp screws evenly to the manufacturer's recommended torque using a torque wrench. Ensure the bellows are not compressed or stretched during installation.

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.
