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

Select a coupling by matching bore diameters to your shaft sizes and ensuring the keyway dimensions align with your shaft keys. For the MBCK57-30-20-A, verify a 30 mm shaft on one side and a 20 mm shaft on the other, both with keyways. RULAND MANUFACTURING offers stainless steel construction for corrosion resistance.

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.
