Hubs

This section will allow you to select hubs to be used individually or as part of an assembly. Ruland manufactures oldham couplings with a proprietary hub machining process that combined with the anodized finish improves lubricity and allows 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
