Hamilton Releases New Ultra Maxi-Duty Caster
Hamilton Caster, Hamilton, Ohio, has introduced the new Ultra Maxi-Duty (UMD) Caster Series with a load rating of up to 40,000 pounds per caster. Targeted for heavy equipment and aerospace manufacturers, defense contractors, and ship builders, the UMD casters are capable of moving loads that previously required six or eight casters with four, simplifying designs and lowering maintenance costs.
The UMD Caster line’s main load bearing assembly has two precision thrust bearings for smooth swiveling: the first thrust bearing is 13” in diameter and features a 234,000-pound load rating, while the second thrust bearing is 7” in diameter and is rated at 100,000 pounds. A third 1-1/2” four-point contact bearing combines with the thrust bearings to provide easier swiveling and durability under extreme loads.
The casters are available with three wheel types: Poly Press-On, forged steel, and Nylast (high capacity cast nylon). Offered in both single-wheel and dual-wheel versions, all models are backed by Hamilton’s three-year product warranty.
