Description
Custom High Precision PU Rollers For Automated Sorting Systems
Why Choose This Product
- Precision Performance: Each roller is machined to tight tolerances (≤0.05mm runout), ensuring consistent package handling and reduced vibration even at high sorting speeds. This advantage minimizes wear on bearings and conveyor belts, extending overall system life.
- Superior Material: Our exclusive polyurethane formulation offers Shore A 80°–95° hardness with excellent abrasion resistance (Abrasion Loss ≤30mm³). Compared to standard rubber, our PU material delivers 3x longer service life in dusty warehouse environments, saving replacement costs and downtime.
- Customization Flexibility: We provide full OEM/ODM/OBM support, including custom dimensions, shaft types, durometer, color, and anti-static or conductive options. Our engineering team works with you to create the perfect fit for your automated sorting system.
- Reliable Quality Assurance: All rollers undergo 100% dimensional inspection, hardness testing, and dynamic balancing (G6.3 grade). Our factory is ISO9001 certified, and we welcome third-party audits or onsite inspections before shipment.
- Proven in the Field: Over 500,000 rollers delivered to material handling customers worldwide, with a <1% field failure rate. Our rollers power sorting systems in major e-commerce, postal, and logistics hubs across Europe, America, and Asia.

Production & Inventory Policy
Lead time: Actual lead times depend on raw material availability, production load, and seasonal peaks. We provide the best possible delivery estimate after order confirmation and keep you informed throughout the process. For urgent projects, please contact us to discuss priority scheduling.
Stock status: We generally produce to order, but a selection of popular roller sizes and durometers may be available in stock. Stock quantities fluctuate with sales and production. We recommend checking real-time availability with our sales team before placing an order.
Bulk & custom orders: For large volumes or custom specifications, please communicate your required timeline early so we can align our production capacity. We will do our utmost to support your schedule.
Frequently Asked Questions
1. What is the typical lead time for custom high precision PU rollers for automated sorting systems?
Lead time varies based on quantity, complexity, and current production load. For standard sizes and moderate volumes (100–500 pcs), typical lead time is 15–25 working days. For large orders or highly custom designs, please contact us for a tailored schedule. We provide realistic estimates and regular updates.
2. Can I get custom samples before placing a bulk order?
Yes, we offer custom samples for evaluation. Sample lead time is usually 7–15 working days depending on specifications. Sample cost is charged separately, but for bulk orders we can often refund the sample fee. We recommend confirming all dimensions, hardness, and shaft requirements before sample production.
3. Do you provide OEM/ODM customization for existing sorting system brands?
Absolutely. As a professional OEM/ODM manufacturer, we can replicate or modify rollers to fit existing systems. Just send us the drawing, sample, or detailed dimensions — our engineering team will propose the best material and core design. We also offer custom branding and packaging for ODM/OBM projects.
4. What is the minimum order quantity (MOQ) for custom rollers?
For standard custom sizes, our MOQ is typically 50–100 pieces per specification. For smaller quantities or prototype runs, please inquire — we try to accommodate R&D or trial projects. For wholesale orders, larger quantities enjoy volume discounts and better lead times.
5. How do you ensure the quality of polyurethane rollers for high-speed sorting applications?
Quality is built into every step. We start with certified raw polyurethane and steel/aluminum, then perform in-process checks on hardness, dimensions, and bonding integrity. Each finished roller is tested for runout (≤0.05mm), dynamic balancing (G6.3), and surface finish. Our ISO9001 system ensures traceability. We also provide inspection reports with every shipment as evidence of quality.
6. What payment methods and shipping options do you accept?
We accept T/T, L/C, PayPal (for samples), and Western Union. Shipping is via sea, air, or express (DHL, FedEx, UPS) depending on urgency and order value. We can arrange door-to-door delivery for most destinations. For large wholesale orders, FOB or CIF terms are welcome.
7. Can you provide anti-static or conductive PU rollers for sensitive electronics sorting?
Yes, we offer ESD-grade polyurethane with surface resistivity in the range of 10⁶–10⁹ Ω/sq. This is ideal for sorting electronics, semiconductor components, or any application where static discharge must be avoided. Our material formulation can be adjusted to meet your specific ESD requirements, and we provide test data with each batch.
8. What is your warranty policy for custom high precision PU rollers?
We provide a 12-month warranty against manufacturing defects under normal operating conditions. This covers delamination, excessive wear, dimensional drift, or premature failure. Our warranty reflects our confidence in the product and our commitment to being a reliable partner. For any quality issues, we offer prompt replacement or repair advice.
