Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling connects two keyed shafts with different bore diameters (1 1/4 in and 1 in) 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 BCK44-20-16-A bellows coupling?

The BCK44-20-16-A is a stainless steel clamp-on bellows coupling for inch-sized keyed shafts. It has a 1 1/4 in bore diameter 1, a 1 in bore diameter 2, and a maximum speed of 10,000 RPM. It includes a keyway and is designed for different bore dimensions.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

How to select a bellows coupling for keyed shafts?

Select a bellows coupling by matching bore diameters to your shaft sizes (e.g., 1 1/4 in and 1 in), verifying keyway dimensions, and ensuring the maximum speed (10,000 RPM) exceeds your application. Choose stainless steel for corrosion resistance. RULAND MANUFACTURING couplings offer zero-backlash performance for precision drives.

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.
