How to select the correct RULAND MANUFACTURING disc coupling for keyed shafts?

Match the bore diameter to your shaft sizes—this model fits 30 mm and 1 in shafts. Verify the OD (3 1/8 in) fits your space, and choose the clamp-on style for easy installation without shaft modification. Ensure torque and misalignment requirements are within the coupling's ratings; consult RULAND's technical data for limits.

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.
