At the forefront of industrial roller technology, our SR Rollers with PU (Polyurethane) Coating represent a perfect blend of durability, versatility, and precision. Designed to meet the rigorous demands of modern manufacturing environments, these rollers feature a high-quality polyurethane coating applied to a robust core material, typically steel or aluminum. The PU coating is not just a protective layer; it's a functional enhancement that provides superior abrasion resistance, chemical tolerance, and consistent performance across a wide range of operating conditions.
PU coating offers unique advantages over traditional roller materials. Its elastic properties allow it to absorb shocks and vibrations, reducing noise and minimizing damage to conveyed materials. Meanwhile, the coating's low friction coefficient ensures smooth material handling, making it ideal for delicate or high-value products. Whether used in packaging lines, printing presses, or automotive assembly, our SR Rollers with PU Coating deliver reliable performance that enhances operational efficiency and reduces downtime.
The polyurethane coating is formulated to withstand heavy-duty use, with a wear rate significantly lower than standard rubber or plastic coatings. This means longer service life even in high-load, high-speed applications, reducing the frequency of roller replacement and associated maintenance costs.
PU is highly resistant to a wide range of chemicals, including oils, greases, and solvents commonly found in industrial settings. This resistance protects the roller core from corrosion and ensures the coating remains intact, maintaining its functional properties over time.
We offer PU coatings in various shore hardness levels (from 30A to 95A), allowing customers to choose the optimal hardness for their specific application. Softer coatings are ideal for gentle material handling, such as conveying glass or electronic components, while harder coatings excel in heavy-duty material transport.
Our PU-coated rollers perform reliably in temperature ranges from -20°C to +80°C, making them suitable for both cold storage facilities and environments with moderate heat exposure. The coating maintains its elasticity and mechanical properties across this range, ensuring consistent performance.
Each roller is manufactured with tight diameter tolerances (typically ±0.05mm), ensuring smooth rotation and minimal vibration. This precision is critical for applications requiring uniform material movement, such as in printing or textile processing.
In packaging lines, our PU-coated rollers facilitate the smooth movement of boxes, cartons, and wrapped products. The low friction coating prevents scratches on product surfaces, while the wear resistance ensures long-term use in high-throughput facilities. Conveyor systems in warehouses and distribution centers also benefit from these rollers, which handle heavy loads efficiently and reduce energy consumption.
Printing presses demand rollers that can maintain consistent pressure and grip without damaging delicate paper or film substrates. The PU coating's elasticity allows for uniform ink transfer, while its resistance to solvents used in cleaning processes ensures longevity in this chemically challenging environment.
In textile mills, our rollers are used in spinning, weaving, and finishing operations. The soft PU coating gently handles fabrics, preventing snags or stretching, while the roller's precision ensures even tension control throughout the production process.
Automotive assembly lines rely on our PU-coated rollers for moving parts such as door panels, dashboards, and painted components. The coating's resistance to oils and greases used in manufacturing protects the rollers from contamination, while its shock-absorbing properties safeguard delicate automotive parts during transport.
In cleanroom environments, where dust and particle contamination are critical concerns, our PU-coated rollers offer a low-outgassing solution. They are used to convey circuit boards, LCD panels, and other sensitive electronic components with minimal risk of static discharge or surface damage.
Q: How do I clean and maintain PU-coated rollers?
A: Regular cleaning with a mild detergent and a soft cloth is usually sufficient. Avoid using harsh chemicals or abrasive materials, as they may damage the coating. Inspect rollers periodically for signs of wear and ensure proper alignment to maintain optimal performance.
Q: Can these rollers be used in wet environments?
A: Yes, PU is highly resistant to water and moisture, making them suitable for applications involving liquid exposure, such as car wash systems or food processing lines with frequent water rinsing.
Q: What is the typical lead time for custom-sized rollers?
A: Lead times vary depending on the complexity of the order, but we generally deliver custom rollers within 2-4 weeks after finalizing the design specifications.
Q: Are there static-conductive PU coatings available?
A: Yes, we offer antistatic PU coatings that dissipate static charges, which are essential for industries handling electrostatic-sensitive materials like electronics and pharmaceuticals.
Q: Can the PU coating be repaired if slightly damaged?
A: Minor surface damage can sometimes be repaired by sanding the affected area and applying a compatible PU topcoat. However, significant damage may require roller re-coating or replacement to ensure performance integrity.
