Premium Heavy Duty Casters with Robust Iron Core & High-Grade PU Surface

Designed for extreme load-bearing up to 800 lbs per wheel, featuring a durable iron core construction with precision-balanced swivel mechanism. The wear-resistant polyurethane (PU) tread ensures silent operation and protects floors from scratches.

Industrial-Grade Braking System & Multiple Size Options (4"/5"/6"/8")

Equipped with a reliable dual-action red brake for instant locking (swivel+rotation). Available in four standard sizes to fit logistics equipment, warehouse carts, automotive workshops, and heavy-duty machinery.

Superior Stability for Demanding Environments

Reinforced steel ball bearings and thickened mounting plates prevent wobbling under dynamic loads. Ideal for uneven surfaces in construction sites, manufacturing plants, and airport baggage handling systems.

Corrosion-Resistant Zinc Plating & Easy Installation

Triple-layer zinc plating protects against rust in humid conditions. Pre-drilled holes with universal bolt patterns enable tool-free attachment to most industrial equipment and DIY utility trailers.

Certified Safe for High-Speed Movement

Tested to meet ANSI/BIFMA standards for smooth rolling at 5+ mph. Non-marking PU wheels maintain traction on concrete, asphalt, and epoxy-coated floors without leaving residue.
