The Ruland Set Screw Oldham Coupling Hub is a component of a three-piece design consisting of two anodized aluminum hubs press-fit onto a center disk. This design allows for a highly customizable coupling that easily combines clamp or set screw hubs with inch, metric, keyed, and keyless bores. Disks are available in three materials, allowing users to tailor the coupling’s performance to their specific application. It can accommodate all forms of misalignment and is especially useful in applications with high parallel misalignment (up to 10% of the OD).

Balanced design for reduced vibration at high speeds

Operates with low bearing loads protecting sensitive system components such as bearings

Machined from bar stock that is sourced exclusively from North American mills

RoHS compliant

REACH compliant

Zero backlash
