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.
