Kingpinless Solid Elastomer Heavy Duty Casters

• 【Ultra Heavy Duty Casters】This extra heavy duty wheel is a solid cast polyurethane elastomer tread that mechanically locks onto a glass filled nylon core. This material and construction ensures that this wheel is extremely rugged and durable with high impact and abrasion resistance to protect equipment and floors as well as many floor surfaces.

• 【Kingpinless Casters】 This wheel utilizes a crown tread instead of the traditional flat tread for better maneuverability, which reduces rolling resistance and aids in swivel action, thus allowing the wheel to move easily under high loads. In addition, the wheels utilize large sealed precision ball bearings, so the wheels require no maintenance for their lifetime.
• 【Adaptable to Various Uses】Polyurethane elastomer composition casters are adaptable to different environments and conditions, resistant to most chemicals, oils, acids, greases and water, providing reliable performance even in extreme industrial environments.
• 【Widely Used】Our casters in this series are suitable for extreme heavy-duty use, with load capacities up to 10,000 lbs. Ideal for manufacturing plants, traction lines, and where tight push/pull forces are required, such as large industrial equipment, institutional machinery, large flatbed carts, material handling equipment, laboratory equipment, hospital equipment office equipment, mobile carts, and utility and maintenance carts.
