Description
Custom Flanged Type PU Rollers For Conveyor Mounting
Why Choose This Product
Our flanged PU rollers are built to solve the most common pain points in conveyor systems: premature wear, noise, and load instability. The polyurethane coating offers exceptional abrasion resistance (tested to ASTM D4060 with <0.08g weight loss per 1000 cycles), which means your rollers last 3–5 times longer than rubber alternatives. The flanged design ensures positive tracking and prevents belt misalignment, reducing maintenance interventions. Each roller is precision-ground to achieve concentricity within 0.1mm, providing smooth and quiet operation even under heavy loads. We also offer custom hub configurations (bore size, keyway, thread) to match your existing mounting hardware, saving you time and retrofit costs. Evidence of our quality includes thousands of units shipped to automotive, logistics, and food processing facilities worldwide, with a repeat order rate exceeding 85%.
Custom roller compounds (PU, NBR, EPDM, silicone, natural rubber, neoprene), hardness from Shore A 20° to 98°, and surface finishes (smooth ground Ra 0.05–0.8µm, textured, grooved) are available. Dynamic balancing tolerance ≤0.05mm. ISO9001 certified, oil‑resistant and wear‑resistant formulas help reduce noise and extend service life.
Typical applications: Conveyor systems (belt, roller, gravity), printing presses (offset, flexo, gravure), packaging machinery, automated production lines, textile processing, paper mills, coating equipment, and material handling.

Product Details & Configuration Options
Our flanged PU rollers are available in a wide range of sizes and mounting styles to suit virtually any conveyor system. The flanged design provides positive lateral guidance, making them ideal for belt conveyors, roller conveyors, and transfer stations where tracking stability is critical. We offer custom bore sizes (from 12 mm to 40 mm), keyways (ASA or DIN standard), and threaded ends for easy installation. For high-temperature or food-grade environments, we can provide FDA-compliant polyurethane compounds and stainless steel cores. Each roller is individually inspected and marked with a unique serial number for full traceability. As a China factory and professional manufacturer, we deliver consistent quality with lead times tailored to your project schedule.

Production & Inventory Policy
Lead time: Actual delivery may vary depending on raw material supply, production scheduling, and seasonal order volume. We provide the best possible estimate after order confirmation and maintain open communication throughout the process.
Stock status: We generally do not hold finished goods inventory, but some popular standard sizes may be available from time to time. Stock levels change dynamically with production and sales. Please confirm current availability with our sales team before placing urgent orders.
Bulk & urgent orders: For large volume or time-sensitive projects, please contact us early so we can review capacity and prioritize your schedule. We will do our best to accommodate your timeline while maintaining quality standards.
Frequently Asked Questions
What is the typical lead time for custom flanged PU rollers?
For standard custom sizes (diameter ≤ 150 mm, quantity under 500 pieces), production usually takes 15–20 working days after sample approval. Larger orders or special compounds may require 25–30 working days. We always confirm the schedule before starting production and keep you updated on progress.
Can you provide custom flange dimensions and bore sizes for my existing conveyor system?
Yes, we specialize in custom solutions. Simply send us your drawing or provide the flange OD, hub bore, keyway spec, and overall length. Our engineering team will review and suggest any improvements for better performance or cost efficiency. We can produce prototypes for testing within 7–10 working days.
What polyurethane hardness do you recommend for heavy-load conveyor applications?
For loads above 500 kg per roller, we typically recommend Shore A 90°–95° hardness combined with a steel core. This provides optimal load-bearing capacity while maintaining enough elasticity to absorb impact. Our lab data shows that Shore A 90° rollers have 30% higher load capacity than Shore A 80° with only a slight increase in rolling resistance, making them ideal for heavy-duty material handling equipment.
Do you offer OEM/ODM services for roller assemblies with brackets or bearings?
Absolutely. As a professional OEM/ODM manufacturer in China, we can supply complete roller assemblies including mounting brackets, bearings, shafts, and circlips. We have experience with integrated designs for AGV drive wheels, transfer carts, and automated sorting systems. Just share your performance requirements and space constraints, and we will propose a tailored solution with expert advice.
What is the minimum order quantity (MOQ) for custom rollers?
Our standard MOQ is 50 pieces for custom sizes. For new customers or prototype validation, we can accept 10–20 pieces at a slightly higher unit price. We aim to support both small-scale testing and large-volume production with competitive pricing and consistent quality.
How do you ensure the rollers are free from defects and perform reliably?
Every production batch is tested for hardness (using Shore A durometer), dimensional accuracy (digital calipers and go/no-go gauges), and visual surface quality. We also perform dynamic balancing on rollers with speeds above 1 m/s. Our ISO9001 system ensures full traceability from raw material to final inspection. For critical applications, we can provide a detailed test report with each shipment.
What payment methods and shipping options do you accept?
We accept T/T bank transfer, L/C at sight, and for established clients, PayPal or Western Union for small amounts. Shipping is via sea (FOB/CIF), air, or express (DHL/FedEx/UPS) depending on your urgency and budget. We have cooperative freight forwarders who offer competitive rates for global shipping, including door-to-door services for many destinations.
