Thombert Poly Load Wheel 5 x 2.88 x 2.44 – 2270-AO

Thombert casts this 5 inch load wheel in Dyalon A polyurethane, a compound chosen for the tread life and chunk resistance a lift truck load wheel needs under repeated cornering and heavy static load. The wheel measures 5 inches in outside diameter and 2.88 inches wide, riding on a 2.44 inch bore that sets the press fit onto the axle. Polyurethane carries the rated load without the flat-spotting and rapid wear that shortens the life of a softer rubber wheel, which is why it is the standard tread for electric material handling wheels.

This is the wheel only, supplied without bearings, so the buyer presses in new bearings or reuses the existing set during the swap. The 2.44 inch bore seats a 6305 series bearing, the size to have on hand before installation. Thombert documents the wheel as fitment for Crown and Hyster 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 bore alone does not fix the bearing width the wheel accepts.
