Thombert Load Wheel Assembly 6 x 3.87 x 3.148 – 5440 AOA

Thombert builds this load wheel assembly on its Dyalon A polyurethane compound, turned to a 6 inch outside diameter across a 3.87 inch tread width with a 3.148 inch bore. Dyalon A is the polyurethane Thombert formulates for load wheels that carry rated weight through long shifts, giving the wheel the load capacity and cut resistance a solid-tread poly wheel needs while running quieter than steel or cast tread on a warehouse floor. The 6 inch diameter and 3.87 inch width set the footprint the truck was engineered around, and the 3.148 inch bore governs the press fit onto the axle.

As an assembly, the wheel arrives with its bearings already pressed into the hub, so it goes onto the axle as a complete unit rather than sending a technician to source and seat bearings separately. Thombert's cross-reference documents this wheel to fit Hyster and Yale lift trucks, matching the hub and bore those trucks run at this size.

Before installing, match the 3.148 inch bore to the axle diameter on the truck, since a press-fit load wheel only seats correctly when the bore and shaft agree.
