Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling connects two round shafts with different bore sizes — 35 mm and 1 in — in motion-control systems. It compensates for misalignment while transmitting torque at speeds up to 10,000 RPM. Common in precision automation, packaging, and machine-tool applications where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BC44-35MM-1"-A bellows coupling?

The BC44-35MM-1"-A is a stainless steel clamp-on bellows coupling with a 35 mm bore on one side and a 1 in bore on the other. It handles a maximum speed of 10,000 RPM and features an inch-to-metric bore configuration. The coupling is designed for round shafts with different bore dimensions and is made by RULAND MANUFACTURING.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

As a global industrial solutions provider, we handle full logistics and customs clearance to ensure the coupling reaches your facility. Contact us for availability and lead time on the BC44-35MM-1"-A or other shaft-coupling configurations.

How to install a clamp-on bellows coupling for round shafts?

To install a clamp-on bellows coupling, first ensure both shaft ends are clean and free of burrs. Slide the coupling onto the shafts, aligning the bores with the shaft diameters. Tighten the clamp screws evenly in a crisscross pattern to the manufacturer’s recommended torque. Avoid over-tightening, which can distort the bellows and reduce performance.

Used in

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.
