Thombert Load Wheel Assembly 4 x 2.5 x 2.047 – ST-2283 AOA

Molded in Thombert's Dyalon A polyurethane, this load wheel assembly measures 4 inches in outside diameter and 2.5 inches wide, riding on a 2.047 inch bore. The Dyalon A compound carries heavy static and rolling loads without the chunking and flat-spotting that shorten the life of a softer wheel, which keeps the wheel round and quiet through a long duty cycle.

The assembly arrives with its bearings already pressed into the hub, built around the 8505 series bearing and set up for greasable service, so the wheel bolts onto the axle as a finished unit rather than sending the buyer chasing a separate bearing and press. The greasable configuration lets a shop re-lubricate the bearing on a maintenance interval instead of retiring the wheel when the grease breaks down.

Thombert documents this wheel as fitting lift trucks from Crown, Hyster, Raymond, Toyota, Yale, Linde, Baker, BT, Prime Mover, and MCFA, which covers a wide swath of the electric-truck and reach-truck population that runs a load wheel of this size. Match the 2.047 inch bore to the axle diameter before installing, since a press-fit wheel only seats correctly on a shaft cut to its bore.
