Basic Information

  • Available Sizes: 4″, 5″, 6″, 8″

  • Load Capacity: 450-800KG

  • Engineered for extreme durability and uncompromising hygiene, our stainless steel kingpinless white nylon impact-resistant casters deliver superior mobility in harsh, sanitary, and heavy-load environments. Combining a high-grade stainless steel swivel rig with a patented kingpinless design, this caster completely eliminates kingpin failure while providing maximum shock absorption and high corrosion resistance. The high-density white nylon wheel is built to withstand severe mechanical impacts, aggressive washdowns, and chemical exposures without chipping or degrading. Designed for zero-downtime operation, it offers an ultra-reliable, non-marking, and effortless rolling solution tailored for food processing, pharmaceutical, and high-capacity industrial applications.


Key Features

  1. Kingpinless Stainless Steel Rig: Combines 304/316 stainless steel corrosion resistance with a kingpinless swivel raceway that eliminates pin shear and handles severe shock loads.

  2. High-Impact White Nylon Wheel: Crafted from ultra-tough, high-density nylon that resists heavy impacts, chipping, moisture absorption, and harsh sanitizing chemicals.

  3. Washdown & Sanitary Design: Smooth surfaces and rust-proof construction prevent bacterial harboring and withstand frequent high-pressure steam and chemical washdowns.

  4. Smooth, Low-Effort & Non-Marking Roll: Precision-machined wheel geometry ensures low rolling resistance, protecting sensitive facility floors while maximizing push/pull ergonomics.

Where to Use Our Casters

  • Meat, Poultry & Food Processing Plants: Perfect for harsh washdown zones exposed to saline solutions, organic fats, and caustic cleaning agents.

  • Pharmaceutical & Medical Cleanrooms: Non-marking, non-sloughing white nylon construction complies with strict sterile environment standards.

  • Chemical & Industrial Processing Facilities: Built to withstand direct contact with solvents, mild acids, and aggressive liquid spills.

  • Cold Storage & Marine Environments: Performs reliably in sub-zero freezers and high-humidity coastal or washdown conditions without rusting.
