Description
Custom Large Diameter PU Rollers for Heavy Load Conveying
Why Choose This Product
Our custom large diameter PU rollers are built with a proprietary polyurethane formulation that provides significantly higher abrasion resistance and load-bearing capacity compared to standard rubber or low-grade PU alternatives. The steel core reinforcement ensures structural integrity under peak loads, while the precision-ground outer surface minimizes vibration and noise during conveying. This design translates into extended service life, fewer replacements, and consistent material handling performance. Evidence from our in-house testing shows these rollers maintaining ≤0.03mm wear after 5000 hours of continuous operation under 80% rated load. With full OEM/ODM support and flexible customization in diameter, hardness (Shore A 70°–95°), and hub configuration, we help you optimize your conveying system for maximum efficiency and total cost savings.
Typical applications: Conveyor systems (belt, roller, gravity), automated production lines, heavy-load transfer carts, warehouse mobile platforms, packaging machinery, and material handling equipment.

Production & Inventory Policy
Lead time: Actual delivery time may vary depending on raw material supply, production schedule, and peak season conditions. We provide a realistic estimated delivery date after order confirmation and maintain regular communication throughout the process.
Stock status: We generally do not keep large inventories, but some popular roller sizes and durometers are in stock. Stock levels change dynamically based on production and sales. Please contact us to confirm real-time availability before placing an order.
Bulk & urgent orders: For large quantities or urgent requirements, we recommend early communication with our team to review capacity and scheduling. We will do our best to accommodate your timeline.
Frequently Asked Questions
1. What is the typical lead time for custom large diameter PU rollers?
For standard custom sizes (diameter up to 400 mm) and moderate quantities (100–500 pieces), production usually takes 15–25 working days. For very large diameters or urgent orders, please contact us for a tailored schedule. We offer express service for an additional fee when production capacity allows.
2. Can you provide customized hardness for my heavy load conveying application?
Yes, we can adjust the polyurethane hardness from Shore A 70° to 95° to match your specific load and impact requirements. For heavy load conveying with high point pressures, we typically recommend Shore A 90°–95° for optimal wear life and load distribution. Our technical team can advise based on your operating conditions.
3. Do you support OEM/ODM with custom dimensions and core designs?
Absolutely. We offer full OEM and ODM services for custom roller diameter, width, core material (carbon steel / stainless steel), shaft size, and mounting configuration. Send us your drawings or specifications, and we will provide a professional custom solution with expert advice and competitive pricing.
4. What is the minimum order quantity for custom large diameter PU rollers?
Our standard MOQ is 10 pieces for custom dimensions and hardness. For smaller quantities, please ask about our sample program. For wholesale bulk orders (500+ pieces), we offer volume discounts and reduced per-unit pricing. Contact our sales team for a detailed quote.
5. How do you ensure quality and consistency for large diameter rollers?
We follow a strict quality control process: incoming raw material inspection, in-process monitoring of PU casting and curing, 100% dimensional inspection, dynamic balancing testing, and a final load test on representative samples. Each roller is marked with a batch number for full traceability. Our ISO9001 system and regular third-party audits ensure consistent quality.
6. Can your PU rollers handle high‑temperature or oily environments?
Our standard PU formulation operates continuously from –20°C to +80°C. For higher temperature or oily conditions, we offer specialized compounds such as high‑temp PU or EPDM. Contact our team for material selection guidance. We have solutions for most challenging environments.
7. What payment methods and shipping options do you accept?
We accept T/T (bank transfer), L/C (letter of credit), and Alibaba Trade Assurance for secure transactions. Shipping can be arranged via sea freight, air cargo, or express courier (FedEx, DHL, UPS) depending on your urgency and budget. We provide FOB, CIF, and DAP terms to suit your procurement needs.
8. What warranty do you offer on large diameter PU rollers?
Standard warranty is 180 days from shipment date against manufacturing defects. Extended warranty (12 months) is available for bulk orders. Normal wear and tear or improper installation is not covered. We stand behind our workmanship and materials.
