Standard Series
We machine our Crown Tread Wheels with a custom radius for better wear than standard industry tapers. All Grey Hub Crown Tread wheels are machined from close grain, porous-free molded castings.
All Grey Hub Flat Tread wheels are machined from close grain, porous-free molded castings.
Geared/Idler Wheels
Grey Hub’s geared wheels are machined from molded gray iron castings and hardened throughout. They are drilled and tapped (with a 3/8″ bolt pattern) to accommodate the removable ring gear making replacement of a worn wheel or ring gear easily accessible. The removable ring gear (sold separately) is machined separately from steel and assembled to the wheel body using four Allen-type set screws – making one rigid assembly!
Custom Wheels
Grey Hub specializes in the design and manufacturing of custom wheel assemblies per your specifications. We can alter or modify our standard wheels or machine complete specials from raw stock up to 10″ diameter, and, in a variety of tread profiles. Custom axles can be machined for special applications or designed for use with different types of bearings.
