About

Hubs

This section will allow you to select hubs to be used individually or as part of an assembly. Ruland manufactures oldham couplings in aluminum with an anodized finish for improved lubricity and stainless steel for corrosive applications. Hubs are manufactured with a proprietary machining process that creates a smooth interaction between the hub tenons and disk allowing for the longest service life in the industry. Torque transmission is achieved by mating the slots on the center disk to the drive tenons on each hub. Oldham couplings can help protect expensive machine components by acting as a torque limiter during overload. The disc breaks cleanly and does not allow for any power transmission. Oldham couplings are also electrically isolating since disks are non-conductive

Hubs
Disks

This section will allow you to select disks to be used individually or as part of an assembly. Ruland offers users the ability to tailor the performance of oldham couplings to match their application needs as disks are available in three materials, acetal for high torsional stiffness and zero-backlash, nylon for shock absorption and noise reduction, and PEEK for high temperature and low outgassing. The slots of the disk mate onto the tenons of the hub with a slight press fit to allow the coupling to operate with zero backlash. In the event of disk wear or failure, the disk can be easily replaced and the oldham coupling's original performance restored. Disks with a center hole are available upon request to allow full shaft penetration.

Oldham Bundle
This section will allow you to select the components to create a complete coupling. Please note that all orders ship unassembled. When you are ordering or downloading CAD all components are individual. They must be specified on any purchase order with a minimum of two part numbers. The combinations listed are a complete offering combining all available hubs and disks.
