6 Inch Polyurethane Caster Wheels Set of 4 - Heavy Duty 4800 lb

In this review of the 6 Inch Polyurethane Caster Wheels set, the bottom line is simple: these are heavy-duty plate casters built for demanding material handling where floor protection and quiet operation matter. The reviewer found them most valuable for industrial trolleys, shop carts, and institutional use because the Pro-Tech Poly tread balances rollability with non-marring performance. Installation is straightforward and the double ball bearings and polyolefin core deliver dependable support, so anyone replacing worn casters or upgrading equipment will appreciate the combination of load capacity and floor-friendly tread.

Key Features

• Pro-Tech Poly tread: Moves quietly while protecting floors from streaks and scuffs during frequent use.
• 6 in diameter, 2 in width: Offers a stable contact patch that helps with load distribution and smoother rolling over small obstacles.
• Double ball bearings: Provide reliable rollability and help the wheels handle repetitive pivoting without early wear.
• 4800 lb capacity (set of 4): Strong load-bearing capability suitable for heavy-duty carts and industrial trolleys.
• Polyolefin core: Keeps the wheel lighter than full metal while maintaining structural strength for industrial use.
• Non-marking formulation: Designed for hospitals, food service, and laboratories where floor appearance and hygiene are important.

Who It's For

These casters are aimed at maintenance teams, shop owners, and facilities managers who need durable, floor-friendly wheels for industrial and institutional equipment. The combination of polyurethane tread and a polyolefin core makes them suitable for environments like bakeries, clinics, schools, and animal labs where non-marring contact and quieter movement are priorities.

Users who require specialty features such as swivel locks, threaded stems, or shock-isolating mounts should look elsewhere, since this product is presented as plate-mounted casters focused on raw load capacity and general-purpose utility rather than specialized steering, braking, or anti-static options.
