Welcome to Henan San Kuang Machinery Technology Co., Ltd. – a professional manufacturer of high-performance polyurethane rollers. Since our establishment in 2022, we have been dedicated to providing durable and precisely engineered rollers for diverse industrial applications. Our factory, spanning 10,000–30,000 square meters, is equipped with advanced testing and production equipment. Every polyurethane roller we deliver undergoes factory testing, dynamic balancing, and is backed by a 1-year warranty and 24/7 technical support. This combination ensures you receive a reliable component that minimizes downtime and maximizes productivity.
Our polyurethane rollers are designed to meet the demanding needs of conveyor systems, printing presses, packaging lines, textile machinery, and mining equipment. The polyurethane material offers excellent wear resistance, high load-bearing capacity, and superior grip compared to rubber or metal rollers. With dynamic balancing, we guarantee smooth operation at high speeds, reducing vibration and noise. Whether you need a standard size or a custom dimension, our team is ready to deliver.
Below we provide detailed technical specifications, product advantages, and answers to common questions to help you make an informed purchasing decision.
Key Features & Technical Specifications
- Material: High-quality polyurethane (PU) – Shore A hardness from 60 to 95, customizable per your application.
- Core Structure: Steel or aluminum core with rubber bonding layer to ensure firm adhesion.
- Dynamic Balancing: All rollers are dynamically balanced to G6.3 grade (ISO 1940), ensuring minimal vibration even at high rotation speeds.
- Factory Tested: Each roller is 100% inspected for dimensional accuracy, hardness, surface finish, and concentricity before shipment.
- 1-Year Warranty: We stand behind our product quality. Any manufacturing defect will be repaired or replaced free of charge within one year.
- 24/7 Technical Support: Our experienced engineers are available around the clock to assist with installation, troubleshooting, and custom requirements.
- Customizable Options: Diameter, length, shaft design, keyways, threading, surface grooving, and color are all available upon request.
- Certifications: Our manufacturing facility complies with ISO9001, ISO14000, OHSAS18001, and other quality management systems (certificates available on request).

Product Advantages & Benefits
- Extended Service Life: Polyurethane is highly resistant to abrasion, tearing, and chemical degradation. Our rollers outlast rubber counterparts by up to 3–5 times in many applications, reducing replacement costs.
- Reduced Downtime: Dynamic balancing minimizes vibration, preventing premature bearing wear and roller misalignment. Factory testing ensures every roller meets strict tolerances, so you can install with confidence.
- Quiet Operation: The inherent damping properties of polyurethane, combined with precise balancing, result in significantly lower noise levels compared to steel or rubber rollers.
- High Load Capacity: Our polyurethane formulation provides excellent compressive strength, allowing the roller to handle heavy loads without deformation.
- Customization Flexibility: We offer a wide range of customizable features – from diameter and length to shaft configurations and surface patterns – allowing you to optimize the roller for your specific machinery.
- Global Support: With 24/7 technical support and multiple shipping ports (Shanghai, Lianyungang, Qingdao, Tianjin), we serve customers worldwide in North America, Europe, Asia, Africa, and Oceania.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for polyurethane rollers?
A: Standard sizes (common diameters and lengths) usually ship within 7–15 working days. Custom sizes may require 15–30 working days, depending on complexity. We will confirm the lead time upon order. -
Q: Can you produce rollers with a specific hardness?
A: Yes, we can adjust the Shore A hardness from 60 to 95 based on your application. For example, softer rollers (60–70A) are suitable for gentle gripping, while harder rollers (80–95A) offer higher wear resistance. -
Q: Do you provide samples before mass production?
A: Yes, we offer sample orders. The cost of the sample is negotiable, and we may deduct it from the bulk order. Please contact our sales team to discuss sample availability. -
Q: How do you ensure the dynamic balancing quality?
A: We use a professional balancing machine that measures unbalance in two planes. Each roller is balanced to G6.3 grade (ISO 1940). The balancing report is available upon request. -
Q: What is the warranty coverage?
A: Our standard warranty covers manufacturing defects in material and workmanship for one year from the date of shipment. It does not cover damage caused by misuse, improper installation, or normal wear and tear. -
Q: Can I get a custom shaft design (e.g., keyway, threading, step)?
A: Absolutely. We can machine the shaft according to your drawing or specifications. Common options include keyways, flat spots, threaded ends, and stepped diameters. -
Q: Do you have certificates for quality management?
A: Yes, our factory is certified under ISO9001, ISO14000, OHSAS18001, and other standards. Copies of our certificates can be provided upon request. -
Q: How do you ship the rollers, and which ports do you use?
