Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling connects two shafts with different bore sizes—30 mm and 1 inch—in motion-control systems. It compensates for misalignment while transmitting torque, making it ideal for precision positioning, robotics, and servo-drive applications where backlash-free operation is critical.

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

This clamp-on bellows coupling has a 30 mm bore diameter 1 and a 1 in bore diameter 2, with a maximum speed of 10,000 RPM. It is made of stainless steel, supports inch-to-metric bore combinations, and is designed for keyed shafts. The manufacturer part number is BCK50-30MM-1"-A.

Contact us for availability and lead time on the BCK50-30MM-1"-A or other RULAND MANUFACTURING motion-control components.

How to select a RULAND MANUFACTURING bellows coupling for keyed shafts?

Select a RULAND MANUFACTURING bellows coupling by matching bore diameters to your shaft sizes—here 30 mm and 1 inch—and verifying the maximum speed (10,000 RPM) exceeds your application. Ensure the coupling material (stainless steel) suits your environment. For keyed shafts, confirm the coupling includes a keyway.

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.
