How to Order

Complete Coupling: Oldham couplings are an assembly of two hubs and one disk

Hubs: Choose two hubs in inch or metric in any style with the same outside diameter

Disk: Choose disk to match performance criteria. The disk must have the same outside diameter as both hubs.

Each hub and disk is sold separately

Note * Recommended rating for maximum life. Maximum allowable parallel misalignment is 10% the outside diameter.
Note 1 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 2 Torque ratings for the couplings are based on the physical limitations/failure point of the torque disks. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the disks. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
