Thombert Load Wheel Assembly 6 x 4 x 2.834 – ST-4831 AOA

Sized for a heavier load wheel position, this Thombert assembly measures 6 inches in outside diameter and a full 4 inches wide, riding on a 2.834 inch bore that equals 72 millimeters. Thombert molds the tread in Dyalon A polyurethane, a compound built to carry high static and rolling loads while resisting the chunking and flat-spotting that end the life of a softer wheel under a loaded truck.

The 4 inch tread width spreads weight over a large contact patch, which lowers floor loading and slows wear, useful on trucks that move heavy loads across a shift. It arrives as a complete assembly with the 6207 bearing pressed into the hub and set for greasable service, so it installs as one unit and the bearing can be re-greased on schedule.

Thombert documents this wheel as fitting Crown, MCFA, and Raymond lift trucks. Match the 2.834 inch bore to the axle diameter before installation, since a press-fit wheel seats correctly only on a shaft turned to its bore, and a mismatch there leaves the wheel loose or impossible to seat.
