Description
Custom Double Flange PU Wheels For Overhead Rail Systems
Why Choose This Product
The double flange profile locks the wheel onto the rail, preventing lateral displacement and reducing the need for frequent track adjustments. Our polyurethane tread is compounded for abrasion resistance, so the wheel keeps its round profile even under continuous shuttling, which extends replacement intervals and reduces downtime. The non-marking surface protects painted or polished rails, making these wheels an excellent choice for clean production areas.
We also support custom solutions for bore size, hub material, hardness, and tread width, helping you retrofit existing overhead conveyor systems without redesigning the entire carriage. Typical applications include overhead rail systems, C-channel tracks, I-beam tracks, trolleys, hoists, shuttle carriages, and automated material handling lines. Dynamic balancing is checked before shipment to reduce noise and extend bearing life.
Typical applications: Overhead rail systems, C-channel and I-beam tracks, trolleys, hoists, shuttle carriages, and automated material handling lines.

Ratings based on in-house testing. Polyurethane offers excellent overall performance for heavy-duty overhead rail wheels – high abrasion resistance and load capacity translate to longer service life and reduced replacement frequency. Custom hardness from Shore A 85 to 95 is available from our factory.
About Us
Customers Visiting
We are a China-based manufacturer focusing on custom polyurethane wheels and rollers for material handling equipment. Our team supports OEM and ODM projects from drawing review, tooling design, and material selection to batch production and export logistics. Beyond double flange PU wheels for overhead rail systems, our production range also includes non-marking silicone coated wheels for smooth conveyor roller applications, sharing the same quality control standards. Wholesale orders are welcome with competitive direct pricing.
Factory & Equipment
Our workshop is equipped with PU mixing and pouring lines, CNC lathes, dynamic balancing machines, and hardness testers. Every custom wheel runs through material preparation, casting, curing, machining, and final inspection. For double flange wheels, we also verify flange symmetry and tread runout before packing.
Our Certifications (ISO9001, RoHS, Testing Reports)
We follow ISO 9001-based quality management practices in our daily production. Material test reports, dimension inspection certificates, and photos from the production line can be shared for your review. If your overhead rail system requires specific compliance documentation, our engineering team will help confirm the applicable standards and prepare the necessary paperwork.
Production & Inventory Policy
Lead time: Production lead times depend on material supply, current machine capacity, and seasonality. We provide a realistic delivery estimate after order confirmation and keep you updated throughout production.
Stock status: We do not keep a large finished-goods inventory by default, but selected standard sizes are occasionally available from stock. Please contact us to check real-time availability before ordering.
Bulk & urgent orders: For bulk orders or urgent projects, please contact us early so we can review capacity and arrange a schedule that fits your timeline.
Frequently Asked Questions
1. What are the advantages of a double flange PU wheel for overhead rail systems?
Custom double flange PU wheels for overhead rail systems provide stable lateral guidance and prevent the wheel from drifting off the track. This reduces rail edge wear and keeps the trolley stable during start/stop cycles. The polyurethane tread also absorbs shock, so loads remain balanced even on slightly uneven rail joints.
2. Can you customize the wheel diameter, bore size, and flange width to fit our existing rail?
Yes. As a top OEM/ODM manufacturer in China, we support customization for bore diameter, hub material, tread width, flange profile, and hardness. If you can provide a drawing or the rail cross-section, our engineering team will advise the correct dimensions and confirm the design before production.
3. What load capacity can these double flange PU wheels handle?
Standard configurations in our catalog typically cover 200–800 kg per wheel, depending on wheel diameter and PU formulation. For higher loads, we can adjust the hub design and tread thickness. We recommend a quick load test or engineering review to confirm the safety factor for your application.
4. Are these PU wheels non-marking on painted or polished rail surfaces?
Yes. Our PU compound is selected to be non-marking and low-abrasion on steel and aluminum rails. This is a clear advantage for clean production areas where conventional rubber wheels may leave dark streaks. We can also provide anti-static formulations if required.
5. What is the MOQ and how long does delivery usually take?
MOQ depends on the wheel size and whether tooling is already available. Standard sizes are more flexible, while fully custom designs may require tooling preparation. We will give an accurate lead time after reviewing your specification — generally 2–4 weeks for medium-sized orders.
6. How do you control quality for custom wheels?
Every batch passes through dimensional checks, hardness testing, and visual inspection. For double flange wheels, we also inspect flange symmetry and runout before packing. Test reports and production photos can be shared during manufacturing if needed.
7. Do you support sampling before mass production?
Yes. We can produce sample wheels for fit testing on your overhead rail system. The sample cost is typically deducted from the first mass order. Development time depends on drawing complexity and material availability.
8. Can we have different colors or a custom logo on the wheel?
PU tread color can be customized to match your equipment or branding. We can also add molded marks on the hub or packaging with your logo. For larger runs, we support custom cartons and export documentation as part of our wholesale service.
