Heavy-Duty Industrial Casters for AGV & High-Load Material Handling

In continuous material handling, the caster usually fails before the equipment does. Under the repeated start-stop cycles of AGVs and powered tuggers, three failure modes drive most unplanned downtime: tread delamination, where the polyurethane wear layer peels away from the wheel core; flat spotting, where prolonged static load presses a permanent indentation that turns every rotation into a jolt; and rising starting resistance, where worn bearings force operators to overpush and stall throughput. we build this category around eliminating those three failures at the load-bearing interface, not around generic mobility.

Delamination begins at the bond line. our heavy-duty wheels use a 95A durometer premium polyurethane tread chemically bonded to a precision-machined iron core. that bond holds the wear layer in place against the lateral shear and dynamic compression generated by forklift transfers and loaded trailer trains, so the tread wears down gradually instead of tearing off. for AGV fleets running fixed directional tracks, a stable wheel diameter across the duty cycle keeps guidance calibration intact.

Starting resistance and flat spotting are bearing-and-material problems. precision dual ball bearings lower the manual push-pull effort needed to break a static load by 15–20%, cutting operator fatigue on manual tuggers and reducing motor draw on AGV fleets every cycle. paired with a high-rebound PU formulation, the wheel resists residual indentation during overnight and weekend standstills, returning to round rather than holding a flat. every assembly in this range is built to ANSI/ICWM and ISO 22883 standard industrial wheel requirements, with dimensional verification on each production batch rather than spot-checking. for a distributor stocking this line, those verified parameters are the resale argument you hand to your own customers.
