Description
Custom Tapered Bore PU Rollers for Direct Shaft Integration
Why Choose This Product
Custom tapered bore PU rollers from our factory solve several common problems in automated guided vehicles and conveyor lines. The precision tapered bore allows fast and accurate direct shaft mounting, reducing installation time and eliminating alignment errors. That translates into less machine downtime and lower maintenance costs for your operation. The high-performance PU coating provides significantly longer service life than standard rubber or plastic covers, especially under abrasive and high-load conditions, so you replace rollers less frequently and cut total operating costs. We back these claims with ISO9001 certified production, dynamic balancing of ≤0.05 mm, and load test reports. For customers with special shaft sizes, our engineering team supports customized bores and OEM/ODM requirements with fast sampling.
Custom roller compounds, hardness from Shore A 70 to 95, and smooth non-marking surface finishes are available. Dynamic balancing tolerance of ≤0.05 mm, ISO9001 certification, and oil-resistant, wear-resistant PU formulas help reduce noise and extend service life.
Typical applications: AGV platforms, heavy-duty conveyor systems, industrial material handling equipment, and automated production lines.

Material Performance
We choose polyurethane for its balanced combination of hardness, elasticity, and resistance. The following table summarizes the key material properties we test regularly to support your custom solution selection.
| Property | Performance | Test method |
|---|---|---|
| Wear resistance | Superior wear life vs. standard rubber; low dust generation | Taber abrasion |
| Load capacity | High radial load due to steel core and dense polyurethane layer | Static load test |
| Noise | Low rolling noise, ideal for indoor automation | dB(A) measurement |
| Chemical resistance | Resistant to oils, grease, and many common solvents | Immersion test |
| Concentricity | Dynamic balancing ≤ 0.05 mm for smooth rotation | Balancing machine |
Product Details
Our tapered bore PU rollers are engineered for direct mounting on precision shafts. The tapered design creates a firm interference fit when pushed onto the shaft, which minimizes vibration and ensures true running. We can customize the taper angle, bore tolerance, and outer profile to meet specific application requirements.
In addition to PU rollers, our production line also includes custom non-marking silicone coated wheels for smooth conveyor roller systems, ideal for cleanrooms, food handling, and other applications where silent operation and stain-free surfaces matter. This broad capability makes us a reliable supplier for multiple roller and wheel needs.

Frequently Asked Questions
1. What is the lead time for custom tapered bore PU rollers?
Lead time depends on the complexity and quantity. For standard sizes with existing molds, production usually takes 10-15 working days. Custom bores or special PU formulations may take 20-30 working days. We always suggest starting a conversation early so we can offer a reliable delivery estimate based on current workload.
2. Can you provide OEM/ODM service for special shaft dimensions?
Yes, we support OEM/ODM for almost all dimensions including custom taper angles, bore diameters, roller widths, and outer profiles. Our engineering team works from your drawings or sample. We can also help with material selection and application advice to ensure the roller truly fits your machine. That is part of our custom solution value.
3. How does the tapered bore design benefit direct shaft mounting?
The tapered bore provides a self-centering effect when the roller is pushed onto a matching shaft, eliminating the need for additional locking elements. This gives you a secure and repeatable installation, reduces vibration, and makes replacement faster. It is particularly helpful in maintenance-heavy conveyor lines where downtime is costly. These custom tapered bore PU rollers are a proven approach for direct shaft integration.
4. What is the minimum order quantity (MOQ)?
Our MOQ is flexible. For stock sizes, we can accept very small trial orders. For fully custom sizes or special PU formulas, the MOQ will depend on production complexity and material procurement. Contact us for the exact MOQ for your specific product.
5. Do you offer non-marking silicone coated wheels for smooth conveyor roller applications?
Yes, we produce custom non-marking silicone coated wheels for smooth conveyor roller systems. These are often used in packaging lines, electronics assembly, and food handling where clean surfaces and low noise are required. We can adjust hardness, color, and thickness according to your product specification.
6. What quality tests do you perform before shipment?
Each roller is inspected for outer diameter tolerance, hardness, and surface finish. In addition, we perform dynamic balancing on rotating assemblies and load tests on representative samples. ISO9001 process controls are applied throughout production, and we provide test certificates if requested. This is our evidence-based commitment to consistent quality.
7. What is your competitive price advantage compared to alternative suppliers?
As a factory-direct manufacturer, we eliminate middleman costs and pass the benefit to you in the form of competitive wholesale price while maintaining professional quality. We also offer expert advice on material selection and design simplification, which can reduce your total ownership cost. For target market volumes, we can provide price suggestions that fit your budget.
