SyncCasters extra heavy duty caster series is engineered for the most demanding industrial applications. This ultra-heavy range delivers load capacities from 0.6T to 3.5T with wheel diameters from 4" to 12" (100mm to 300mm), featuring MC nylon, steel core PU, rubber, anti-static and full steel wheels with reinforced heavy-duty brackets. Ideal for heavy machinery, large storage systems, industrial transport and warehouse equipment.
Extra Heavy Duty Caster Series Overview
Our extra heavy duty range is built on three sub-series. Series I (low core) offers MC nylon, steel core PU, rubber, anti-static and full steel wheels from 3" to 8", perfect for medium-heavy loads. Series II covers 4"-8" wheels with a load rating of 0.6T-2.5T, built on 100x55mm to 250x55mm specifications with twin-wheel nylon, steel core PU, MC square-edge nylon and full steel options. Series III is our top tier - 6" to 12" wheels (150mm to 300mm) supporting 1.5T to 3.5T loads for the heaviest industrial applications.
Wheel & Bracket Options for Ultra Heavy Loads
MC nylon wheels deliver exceptional hardness and wear resistance for smooth factory floors. Steel core PU wheels combine a metal core with elastic polyurethane for shock absorption and floor protection. Full steel wheels are built for the harshest environments with maximum strength. Anti-static options protect sensitive electronic equipment. Heavy duty brackets feature reinforced steel plates - our Series II brackets use 10mm base plates with 8mm side plates - for reliable performance under continuous heavy loads.
