Description
Custom Low Friction PU Rollers For High Speed Sorting Machines
Why Choose This Product
Our custom low friction PU rollers are purpose-built for high-speed sorting environments where accuracy, uptime, and low operating cost matter most. The key advantages include:
- Low coefficient of friction (0.08–0.12) enables energy-efficient high-speed operation and reduces heat build-up.
- PU coating with Shore A 90±2° hardness provides excellent wear resistance, extending roller service life under continuous 24/7 running conditions.
- Hardened steel core with dynamic balancing ≤0.05mm minimizes vibration, protecting sensors and ensuring stable package tracking.
- Non-marking surface avoids damage to packaging and printed labels, a critical requirement for e-commerce sortation.
- Full customization support for diameter, length, bore, keyway, and surface treatment; OEM/ODM projects welcomed.
- Every batch is inspected per ISO9001 procedures, with dimensional reports and material test certificates available for customer review.

Product Details & Application Examples
Our low friction PU rollers are widely adopted in sorting and conveying equipment such as cross-belt sorters, shoe sorters, sliding shoe systems, and vertical sortation modules. High-resolution product photos, dimension drawings, and application videos can be sent to you for evaluation — just contact our team and we will provide the complete package. Since every sorting line has a unique combination of package weight, belt speed, and sensor layout, we encourage customers to share their operating conditions so we can match the correct hardness, surface finish, and core type.
- Cross-belt sorters used in e-commerce fulfillment and parcel hubs
- Linear sorters and bomb-bay sorters for overnight delivery networks
- Airport baggage handling conveyors requiring stable low-noise rollers
- Incline and decline sections where low friction prevents package jams
- High-speed diverting zones with frequent start-stop cycles
Custom shaft machining, bearing housing selection, and antistatic surface treatments can be engineered to match your existing sorting machine models.
About Our Factory & Equipment
About Us
Customers Visiting
As a China-based manufacturer and OEM/ODM supplier of polyurethane rollers and elastomer components since 2012, we serve sorting machine manufacturers, conveyor integrators, and spare-parts distributors in over 40 countries. We offer customization — from roller hardness (Shore A 90±2°) to core materials and surface patterns. Our products are tested to meet ISO9001 standards, supporting reliable performance for your high-speed sorting equipment. Wholesale orders are welcome with competitive direct pricing. Our production floor of 2,500 square meters is equipped with CNC lathes, automatic centrifugal casting lines, and dynamic balancing machines, allowing us to maintain strict tolerance control and short production lead times for both prototype orders and high-volume supply.
Factory & Equipment
Our Certifications & Quality Assurance
Our manufacturing facility is ISO9001:2015 certified, and our PU rollers meet RoHS and REACH requirements for materials. Each shipment can be accompanied by dimensional inspection reports, hardness test certificates, and surface quality records. We also support pre-shipment third-party inspections and will work with your quality team to agree on acceptance criteria before mass production.
Production & Inventory Policy
Lead time: Our standard lead time is 15–25 working days. Actual delivery can fluctuate due to raw material supply, equipment utilization, or seasonal peak loads in the factory. We provide an accurate shipping estimate after order confirmation and will keep you updated throughout production.
Stock status: In principle we do not hold large finished-goods inventory, but selected fast-moving standard roller sizes are kept in stock. Stock levels change dynamically with sales and production, so we recommend confirming real-time availability with our sales team before ordering.
Bulk & urgent orders: For large-volume wholesale projects or urgent sorting line maintenance needs, please contact us early to align production capacity. We will do our best to fit your target schedule.
Frequently Asked Questions
1. Can you provide custom sizes for PU rollers used in sorting machines?
Yes, custom dimensions are our core strength. We can produce outer diameters from 30 mm to 200 mm and roller lengths from 50 mm to 800 mm. Shaft types, bore sizes, keyways, and surface finishing can all be customized based on your drawings or a physical sample. We provide full OEM/ODM support for both new machine projects and replacement applications.
2. How does the low friction surface benefit high-speed sorting systems?
The coefficient of friction of 0.08–0.12 means the roller surface glides smoothly over package surfaces with less drag. In practice, this lowers the motor torque required to maintain sorting speed, reduces heat generation, and minimizes wear on both the roller and the conveyor belt. The low-friction surface also contributes to quieter operation, which improves the working environment in distribution centers.
3. What is the minimum order quantity and typical delivery time?
The MOQ for standard-size rollers is 10 pieces for initial sampling. For custom-engineered rollers, the MOQ depends on the complexity of the tooling and materials. Normal lead time is 15–25 working days after order confirmation. If you have an urgent requirement, talk to our sales team — we will try to adjust the production schedule where possible.
4. What quality checks do you perform before shipping?
Every roller undergoes 100% dimensional inspection and a visual surface check before packing. Hardness, friction, and dynamic balancing tests are performed on a batch basis following our ISO9001 quality plan. Material test certificates and dimensional reports are provided with each shipment. Third-party pre-shipment inspections are also welcome.
5. Do you also supply non-marking silicone coated wheels for conveyor rollers?
Yes, we produce non-marking silicone coated wheels as an alternative to PU rollers. Silicone coatings offer a softer contact surface, which is suitable for conveying finished painted parts, glass panels, or polished stainless steel products where scuff prevention is critical. If your application requires silicone, our engineers will recommend the correct durometer and coating thickness.
6. How can I order the right PU rollers for a new sorting machine line?
Please provide the following information: roller diameter and length, shaft diameter and end configuration, expected load per roller, line speed in meters per second, and the type of packages being sorted. If you do not have drawings, send us a sample or the current roller part number and we can reverse-engineer the component. Our engineering team will prepare a fit analysis and quotation within one to two business days.
