Value Brand Rigid Plate Caster Poly 6 in 900 lb

Rigid Plate Caster for Heavy Loads

This rigid plate caster uses a 6 in polyurethane wheel on a polyolefin core to support equipment rated up to 900 lb. The non‑marking tread protects finished floors while the fixed housing keeps travel straight without a swivel mechanism. It is intended for carts, work platforms or material‑handling frames that need a single, durable wheel assembly. California Proposition 65 warnings apply to chemicals in the product.

Mounting and Clearance Considerations

The plate bolts directly to a flat frame or deck, so the structure must provide a rigid mounting surface and enough vertical space for the 6 in wheel diameter. No brake or swivel lock is included, meaning the caster rolls freely once installed; builders who need directional locking or a total‑lock brake must add those separately. The polyurethane tread resists flat‑spotting under static loads, freeing the user from frequent wheel replacement.

Behaviour Under Sustained Load

Under continuous 900 lb loading the polyurethane tread distributes pressure evenly across its 2 in width, reducing permanent deformation during long dwell times. The polyolefin core maintains structural rigidity without absorbing moisture, so rolling resistance stays consistent in humid or wash‑down environments. Because there is no brake mechanism, heat buildup from braking cycles does not occur, leaving the wheel bearings and tread to operate at steady temperatures.
