Thombert Poly Load Wheel 4 x 2.5 x 2.047 – ST-2283

Thombert builds this polyurethane load wheel to a 4 inch outside diameter, a 2.5 inch width, and a 2.047 inch bore, the bore being the dimension that fixes how the wheel presses onto its axle. The polyurethane tread carries the concentrated, slow-rolling loads that pass through a lift truck's load wheels, holding its form under a parked weight far better than a softer rubber that flat-spots and chunks. The hub is bored to the 8505/18 bearing series, a known seat that keeps replacement bearings straightforward.

Fitment is documented across a broad set of makes: this wheel fits BT and Prime Mover, Crown, Hyster, Linde and Baker, MCFA, Raymond, Toyota, and Yale lift trucks, which makes it one of the more universal load wheels to keep on the shelf for a mixed fleet. Load wheels ride low on the truck and take the full load through a small contact patch, so they wear on a predictable cycle and are changed out well before the tread reaches the hub.

Before installing, match the 2.047 inch bore to the axle, since a press-fit wheel will not seat on a shaft it was not sized for, and confirm the bearing seat so new bearings match the 8505/18 series this hub carries.
