Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling (BCK44-35MM-1-1/4"-A) is used to connect two shafts with different bore sizes—35 mm and 1 1/4 in—in motion control applications. It compensates for misalignment while transmitting torque, making it suitable for precision machinery, encoders, and servo systems.

What are the specifications of the RULAND MANUFACTURING BCK44-35MM-1-1/4"-A bellows coupling?

This clamp-on bellows coupling has a 35 mm bore diameter 1 and a 1 1/4 in bore diameter 2, accommodating inch to metric bores. It is made of stainless steel, has a maximum speed of 10,000 RPM, and is designed for keyed shafts. The manufacturer part number is BCK44-35MM-1-1/4"-A.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

You can source the RULAND MANUFACTURING BCK44-35MM-1-1/4"-A bellows coupling from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

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

To install this RULAND MANUFACTURING 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 shafts are aligned within the coupling's misalignment limits to avoid premature wear.

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.
