Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling connects a 1 3/4 in keyed shaft to a 40 mm keyed shaft, transmitting torque while compensating for misalignment. It is used in precision motion control, servo systems, and industrial machinery where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BCK50-1-3/4"-40MM-A?

This coupling has a 1 3/4 in bore diameter and a 40 mm bore diameter, both for keyed shafts. It is made of stainless steel, supports a maximum speed of 10,000 RPM, and features a clamp-on design for inch-to-metric bore applications.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

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

Align the coupling bores with the keyed shafts, ensuring the key is seated properly. Tighten the clamp screws evenly to the manufacturer's recommended torque using a torque wrench. Avoid over-tightening, which can distort the bellows. Verify alignment with a dial indicator before final tightening.

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.
