Basic Information

• Available Sizes: 3″, 4″, 5″

• Load Capacity: 80-130KG

• Our Medium Duty Red Polyurethane (PU) Stainless Steel Casters are designed for smooth, high-capacity mobility in demanding industrial and commercial environments. Featuring high-grade, resilient red PU treads chemically bonded to heavy-duty cores, these casters are paired with rust-proof Grade 304/316 stainless steel brackets. Delivering a reliable load capacity of up to 130 kg per unit, they come equipped with double ball-bearing swivels to guarantee effortless maneuvering, floor protection, and maximum resistance to moisture, oils, and grease.

Key Features

1. Floor-Saving Ergonomics: The polyurethane tread deforms slightly under load to maximize floor contact, providing excellent traction, minimizing floor wear, and reducing the physical effort required by workers to push heavy carts over door tracks or uneven surfaces.

2. Oil, Grease & Chemical Immunity: Polyurethane is exceptionally resistant to petroleum products, lubricants, cutting fluids, and mild acids, making these casters highly durable in industrial workshops and automotive plants where spills are common.

3. Maintenance-Free Durability: Designed for longevity with rust-proof hardware that requires no frequent greasing, significantly reducing downtime in industrial or commercial operations.

4. Delamination-Free Bond: Our advanced chemical bonding process ensures the Red PU tread remains permanently fused to the wheel core, eliminating the risk of tread separation or peeling under continuous rolling or humid conditions.
