Description
Custom PU Wheels With Grease Fitting For Carts – Heavy Duty Polyurethane Coated Wheel, 300kg Load, Wear-Resistant for Material Handling Equipment
Why choose this product?
Designed for heavy-duty industrial carts and automated transport systems. Each wheel features a steel core with a durable polyurethane coating that absorbs shock, resists oil and chemicals, and provides excellent traction on various floor surfaces. The integrated grease fitting allows periodic lubrication without disassembly, which reduces rolling resistance and wear. Advanced bonding technology eliminates delamination even under continuous high-load operation.
Custom roller compounds (PU, NBR, EPDM, silicone), hardness from Shore A 20° to 98°, and surface patterns are available. Dynamic balancing tolerance ≤0.05mm reduces noise and extends bearing life. ISO9001 certified, our wheels are ideal for factory carts, warehouse platforms, logistics automation, and assembly stations.
Typical applications: Platform carts, heavy-load transfer carts, AGV transport systems, automated production lines, warehouse sorting equipment, and assembly stations.

Material Properties
| Property | PU Tread | Steel Hub | Advantage |
|---|---|---|---|
| Hardness | Shore A 85° | HRC 28-32 | Reduces floor marking |
| Wear Resistance | Excellent (abrasion test grade 5) | N/A | Longer wheel life |
| Load Capacity | 300 kg per wheel | Strong core support | Supports heavy loads without deformation |
| Maintenance | Grease fitting | Rust-resistant coating | Easy lubrication, less downtime |
Ratings: 1 = low, 5 = high. Polyurethane offers excellent wear resistance and load capacity, which directly translates to longer service life and reduced replacement frequency for your cart wheels. Custom hardness from Shore 20A to 98A is available from our factory.

Frequently Asked Questions
1. Are these custom PU wheels with grease fitting available for OEM orders?
Yes, we offer full OEM/ODM services. You can specify the diameter, tread hardness, hub color, and even engrave your brand logo. As a top OEM manufacturer in China, we provide expert guidance on technical parameters to match your cart application perfectly.
2. What is the minimum order quantity (MOQ) for custom PU wheels?
Our standard MOQ is 100 pieces per size. For first-time trials or small-scale projects, we can accommodate lower quantities with slightly adjusted pricing. Please contact our sales team for a personalized quotation.
3. How does the grease fitting benefit my carts?
The grease fitting allows you to periodically lubricate the bearings without disassembling the wheel. This reduces friction and wear, ensuring smooth rolling even under continuous heavy loads. The result is fewer part replacements and lower maintenance costs over the equipment’s lifetime.
4. Can these wheels handle wet or oily workshop floors?
Yes, the polyurethane tread is resistant to oil, grease, and water, providing good traction in most industrial environments. However, for extremely slippery conditions, we recommend a tread with appropriate tread pattern or a softer durometer. Our engineers can help you select the right variation.
5. What is typical delivery time for a 500-piece order?
Delivery time depends on the current production schedule and material stock. For a typical run of 500 wheels, we usually quote 15-25 working days. We always advise confirming specific lead time with our sales team before ordering.
6. Do you provide custom samples before bulk production?
Absolutely. We can produce a few sample wheels matching your desired specifications for evaluation. Sample orders are subject to a small fee, which is refundable upon bulk order placement. This helps us ensure the custom solution meets your expectations.
