Industrial-Grade 4-Inch Casters for Machinery and Workbenches

Revised Content:

【Extra Heavy Duty Casters】The WBD WEIBIDA set of 4, 4-inch heavy-duty industrial casters was designed with strength and sturdiness in mind, ensuring a long lifespan and easy movement of large, heavy loads. Each caster can support a maximum of 800 lbs., or 3200 lbs. when purchasing a set of 4.

【Maintenance-Free Casters】The 4-inch heavy-duty industrial grade casters are designed to roll easier and last longer than rubber-on-iron wheels. The polyurethane wheel tread is made of high-quality liquid-cast polyurethane, chemically bonded to the aluminum core to prevent any thread debonding. The aluminum wheel core is lightweight compared to a cast iron wheel core and will not rust.

【Ergonomic Polyurethane on Aluminum Casters】These 4-inch casters are lightweight and ultra-durable, with a very high strength-to-weight ratio, designed to have an extended lifespan under heavy loads. The aluminum wheel core has a strong metallic look, which can be more aesthetically pleasing than cast-iron core wheels, providing flexibility for use in industrial applications and those requiring a more ergonomic-specific design.

【Wide Application】The WBD WEIBIDA 4-Inch heavy-duty castors with polyurethane on aluminum wheels offer abrasion resistance, oil, and chemical resistance, and are non-marking, helping to protect your floors. These wheels are popular in applications such as Research Laboratories, Hospitals, Bakeries, and many Industrial Manufacturing facilities.

【Double Ball Raceways】The top plate swivel casters with brake feature double ball raceways for added load capacity and durability, resulting in low frictional resistance and a high speed limit, making them easier to move. Plus, the 360-degree rotation top plate allows a little strength to easily transform the direction as needed.
