Oldham Couplings

Ruland oldham couplings, available from Pacific International Bearing Sales, are ideal for stepper and servo systems requiring high parallel misalignment capability and zero-backlash performance. Featuring a customizable three-piece design, two anodized aluminum hubs press fit into a center disk, minimizing bearing loads while maintaining precise motion control. These couplings are balanced for smooth operation at speeds up to 4,500 RPM and are available in clamp or set screw styles with or without keyways, in bore sizes from 1/8" to 1-1/4" and 3mm to 30mm. Center disks come in three material options to suit different application demands.
