Flat Tread Wheels

Standard Series

 For use on Wide Flanged Beam, Angle Iron and Patented Track

All Grey Hub Flat Tread wheels are machined from close grain, porous-free molded castings. They are hardened and heat-treated through-out (not case-hardened) in an atmospheric furnace, oil quenched to eliminate distortion under high heat temperatures, producing uniform hardness for long, trouble-free service, under heat and other severe conditions.

All assemblies come equipped with a heavy duty jam nut, lock washer and grease fitting.
