Thombert Poly Load Wheel 6 x 4 x 2.834 – ST-4831

Thombert casts this polyurethane load wheel to a 6 inch outside diameter, a 4 inch width, and a 2.834 inch bore, the larger-diameter build used where a lift truck load wheel carries more weight per station. The 2.834 inch bore governs the press fit onto the axle, and getting that fit right is what keeps the wheel running true rather than wobbling under a loaded mast. Polyurethane gives the tread its load capacity and abrasion resistance, holding its shape through the repeated start, stop, and turning loads a warehouse floor puts on a wheel.

The bore is sized to take a 6207-series bearing, a standard seat rather than a proprietary one. Thombert documents fitment across Crown, MCFA, and Raymond lift trucks in its equipment cross-reference, which makes this wheel a broad replacement for shops running those brands. As the tread wears down or begins to flat-spot, traction and ride quality drop off, the signal that the wheel has reached the end of its service life.

Match the 2.834 inch bore to your axle diameter before installation, since a press-fit wheel will not seat squarely on a shaft cut to the wrong size. Forklifts Etc. carries this Thombert wheel as a direct dimensional replacement.
