Description
Custom High-Grip PU Rollers for Inclined Belt Conveyors
Why Choose This Product?
Inclined belt conveyors place a unique load on each roller: the belt must maintain traction on a slope, and any slippage can disrupt the entire line. This design makes our rollers a top choice for incline sections in warehouse sorting lines, mining conveyors, and distribution centers. The steel core is welded and balanced for high-load reliability, and the PU coating is poured, ground, and inspected in our own workshop.
- High-grip polyurethane coating formulated for inclined conveyors maintains stable traction on slopes up to 25 degrees.
- Steel core construction offers high load capacity, preventing deformation and extending the service life of the whole conveyor system.
- Optional non-marking silicone coated surface keeps goods spotless, which matters in food, pharmaceutical, and textile production.
- Hardness can be tuned between Shore A 60 and 90 degrees to match your belt type and operating conditions.
- Every roller is dynamically balanced to 0.05 mm or less to reduce vibration, noise, and accelerated wear.
- Standard sizes are available for immediate wholesale supply, while non-standard dimensions can be produced as customized products with a short development cycle.
Typical applications: Inclined sections of warehouse sorting lines, mining conveyors, distribution centers, and heavy-load material handling systems where back-sliding or belt slippage must be avoided.

Custom Non-Marking Silicone Coated Smooth Conveyor Rollers
The smooth conveyor roller series in our range is widely used in package handling lines, belt conveyors, and roller bed equipment. The optional silicone coated surface is designed for applications where product appearance cannot be compromised by black rubber marks. Customers who buy this series as a customized solution receive rollers produced with the same steel core, balancing, and inspection standard as our standard high-grip PU rollers, so the whole conveyor system stays consistent in fit and performance.

Material Properties
The performance of a conveyor roller depends largely on the coating material. Our PU formula is selected for a balanced combination of grip, wear resistance, and elasticity, and the non-marking silicone coated version adds surface cleanliness without sacrificing rolling smoothness.
| Property | Typical Value | What It Means For Your Conveyor |
|---|---|---|
| Coating Hardness | Shore A 60 to 90 degrees | Lets you match the grip level to the belt material and load weight |
| Coefficient of Friction | 0.55 to 0.70 against a standard conveyor belt | Prevents back-sliding on inclined belt conveyors and improves stopping accuracy |
| Abrasion Resistance | Low surface loss in continuous load tests | Extends the roller replacement interval and lowers spare-part cost |
| Oil and Grease Resistance | Good | Keeps stable traction in workshops with lubricated chains and gear motors |
| Temperature Range | -20 degrees Celsius to +80 degrees Celsius | Works reliably in cold storage and warm production areas |
| Load Capacity | Up to 1,200 kg per roller, size dependent | Suitable for heavy-duty transfer carts and large-package conveyor lines |
These values reflect our factory test results for the custom high-grip PU rollers for inclined belt conveyors. Custom Shore A hardness from 60A to 90A is available to match your belt type and load conditions.
About Us
Factory Overview
Customers Visiting
We are a China-based manufacturer and supplier dedicated to conveyor rollers, PU wheels, and material handling components for global industrial markets. Since 2012, our factory has supplied clients in more than 30 countries with both standard wholesale products and fully customized OEM/ODM/OBM solutions. Our engineering team provides practical expert advice on material selection, surface treatment, and load calculations to help you improve conveyor design. For every project, we give clear price suggestions based on real market conditions, and we keep an open line of communication from sample stage to final delivery.
As a China-based manufacturer and OEM/ODM supplier of conveyor rollers and elastomer components, we offer customization — from roller hardness (Shore A 60A~90A) to core materials, shaft types, and surface patterns. Our products are tested to meet ISO9001 standards for reliable performance in your conveyor equipment. Wholesale orders are welcome with competitive direct pricing.

Frequently Asked Questions
Why is the high-grip PU surface important for inclined belt conveyors?
Incline sections add extra stress to the belt, and if the roller surface lacks friction, the material can slide backward and cause jams. Our high-grip PU coating provides a coefficient of friction of 0.55 to 0.70 against a standard belt surface, which helps the belt maintain solid contact on slopes up to 25 degrees. This is why our custom high-grip PU rollers for inclined belt conveyors are tested under 10,000 hours of continuous operation at normal load.
Can you customize the roller diameter, length, hardness, and shaft type?
Yes. As a professional custom solution manufacturer in China, we support OEM/ODM requests for standard and non-standard specifications. Roller diameter can be customized from 48 mm up to larger sizes, length up to 3,000 mm, Shore hardness from 60A to 90A, and shaft types include threaded, spring-loaded, flat, and keyway designs. Send us a drawing or sample, and our engineers will provide expert advice on the most suitable configuration.
What is the difference between high-grip PU rollers and non-marking silicone coated wheels?
High-grip PU rollers focus on traction and load support for inclined belt conveyors, while non-marking silicone coated wheels are chosen when goods and belts must be kept free of black marks. The smooth conveyor roller series can combine both features: a PU base for impact resistance plus a non-marking silicone coated surface for clean handling. This hybrid option is suitable for food packaging, textile, and electronic product conveyors.
What is the MOQ for wholesale orders?
For regular sizes, the MOQ is generally 10 pieces. For custom dimensions, special coatings, or unusual shaft types, the MOQ depends on the material and production complexity. We also welcome small trial orders so you can evaluate the quality before purchasing a larger quantity.
What is your delivery time?
Regular sizes are normally shipped within 15 to 20 working days after payment confirmation. Customized rollers may take 20 to 30 working days, depending on the current production schedule and raw material availability. We give a realistic lead time estimate at the time of order confirmation and inform you as soon as possible if any adjustment is needed.
What packaging and payment methods do you offer for export?
Rollers are packed with foam protection, reinforced cartons, or wooden pallets depending on size and quantity. Common payment terms are T/T and L/C, and for smaller amounts we can support secure online transfers. Shipment can be arranged by sea, air, or express to suit your delivery deadline.
Do you provide warranty and after-sales support?
We provide a 12-month limited warranty against manufacturing defects. Each batch is inspected for dynamic balancing, surface finish, and coating adhesion before shipment under our ISO9001:2015 system. If a quality issue is confirmed, we replace the affected rollers or offer a fair solution after technical review.
