Thombert Poly Load Wheel 3.25 x 4.5 x 2.44 – 2239-B

Thombert casts this load wheel in polyurethane at a 3.25 inch outside diameter, 4.5 inches wide, on a 2.44 inch bore that sets the press fit onto the axle. The wide 4.5 inch tread spreads the load across a larger contact patch, suited to the load-roller positions that carry concentrated weight on electric lift trucks. Polyurethane holds its rated load and resists the flat-spotting and chunking that end a softer rubber wheel early, which is why it is the standard tread for material handling load wheels.

The 2.44 inch bore seats a 6206 series bearing, the size to have in hand before installation. Thombert documents the wheel as fitment for Clark and Crown lift trucks, matching the load-wheel positions those trucks run.

Match the 2.44 inch bore to the axle before pressing the wheel on, since a press-fit wheel will not seat squarely on a shaft of the wrong diameter. Confirm the bearing series against the hub as well, because a shared bore does not fix the bearing width the wheel accepts. Forklifts Etc. lists this as a direct-size replacement for the worn wheel in that position.
