The Waterproof Thread Stem Medium Duty Industrial Caster Wheels are engineered as a corrosion-resistant and high-performance mobility solution for demanding industrial environments. Crafted with premium PVC bearings and durable wheel materials like PP/PU/TPR/PVC, these casters are designed to thrive in settings exposed to chemicals, moisture, or harsh cleaners. With load capacities ranging from 110KGS to 140KGS, they cater to medium-duty applications, ensuring stable and smooth movement across various surfaces. Available in 3”, 4”, and 5” wheel sizes, these casters are versatile enough to fit carts, racks, medical equipment, and more, making them a top choice for industries prioritizing reliability and longevity.
The combination of PVC bearings and chemical-resistant wheel materials (PP/PU/TPR/PVC) provides exceptional protection against acids, alkalis, industrial solvents, and moisture. Unlike steel or PU bearings, PVC bearings are non-reactive to most common chemicals, preventing corrosion and degradation. The sealed housing of the double-bearing design keeps out liquid and dust, ensuring consistent performance even in damp or spill-prone areas.
Built for medium-duty use, these casters support 110–140KGS, with a double-track swivel design and double ball bearings that enhance load-bearing capacity and enable smooth rotation. The robust wheel body (available in PP/PU/TPR/PVC) resists wear and tear, while the waterproof thread stem eliminates rust risks, extending the product’s lifespan in wet environments like commercial kitchens or refrigerated storage.
PVC bearings reduce rolling resistance, making the casters easy to steer and minimizing noise—ideal for medical facilities or office-adjacent industrial spaces. The universal wheel sizes (3”, 4”, 5”) and compatible mounting plates (9666mm or 7545mm) ensure seamless integration with standard industrial equipment, enhancing mobility across diverse applications.
These waterproof industrial caster wheels are tailored for industries where chemical exposure, moisture, or hygiene is critical:
Laboratories: For reagent carts and equipment requiring resistance to acids/alkalis.
Food Processing Plants: Food-grade PP/PVC materials comply with FDA/EU standards, suitable for production line carts.
Chemical Storage Facilities: Corrosion-resistant design protects against solvent spills and moisture.
Medical Facilities: Quiet operation and hygienic materials fit medical equipment and supply carts.
Warehouses & Logistics: The 4” size (125KGS capacity) is ideal for pallet jacks, with waterproof features resisting floor cleaners.

Color Options: Available in orange, red, black, green, or white to match equipment or facility aesthetics.
Dimensional Adjustments: Modify mounting plate sizes or thread stem lengths for specialized equipment compatibility.
Bulk Order Support: Tailored solutions for large-scale industrial projects, with competitive pricing and timely delivery.
PVC bearings resist most household and industrial chemicals, including dilute acids, alkalis, detergents, and mineral oils. Avoid prolonged contact with concentrated sulfuric acid or strong solvents like acetone to maximize lifespan.
Yes. The waterproof and rust-free design, combined with weather-resistant materials, makes them suitable for covered outdoor industrial areas (e.g., loading docks) exposed to moisture.
Minimal maintenance is needed. Wipe down the wheels and bearings with a damp cloth to remove debris—no greasing is required, as PVC bearings are self-lubricating and resistant to friction.
The 32mm tread width and stable double-track swivel design ensure stability on slightly uneven industrial floors, though smooth surfaces are recommended for optimal performance and longevity.
