Oldham Coupling 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
Features Large parallel misalignment
Electrically isolating
Replaceable disk
Balanced design
Constant velocity
RoHS3 and REACH Compliant
Maximum speed: 4,500 RPM
Temperature range (Deg. F)with Acetal Disk:
-10° to 150°
with Nylon Disk:
-10° to 130°
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.
