Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

A RULAND MANUFACTURING bellows coupling connects two shafts while compensating for misalignment. This clamp-on model is designed for keyed shafts with different bore dimensions, such as 1 3/4 in and 30 mm, and is used in precision motion control applications like encoders and servo drives.

What are the specifications of the RULAND BCK50-1-3/4"-30MM-A bellows coupling?

This RULAND MANUFACTURING bellows coupling has bore diameters of 1 3/4 in and 30 mm, a maximum speed of 10,000 RPM, and is made of stainless steel. It features a clamp-on design for keyed shafts and an inch-to-metric bore configuration. The manufacturer part number is BCK50-1-3/4"-30MM-A.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

3G Electric supplies RULAND MANUFACTURING bellows couplings worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the BCK50-1-3/4"-30MM-A or other RULAND coupling models.

How to select a RULAND bellows coupling for keyed shafts?

To select a RULAND bellows coupling, match bore diameters to your shaft sizes—this model fits 1 3/4 in and 30 mm. Ensure the coupling type (clamp-on) and material (stainless steel) suit your environment. Verify max speed (10,000 RPM) exceeds your application's requirements. RULAND couplings are designed for precision alignment.

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.
