Our polyurethane rollers are manufactured using advanced casting and machining techniques, ensuring tight tolerances and consistent quality. The 80A shore hardness provides excellent resistance to permanent deformation, making these rollers suitable for high-speed packaging lines where rollers are subjected to constant pressure. Additionally, the polyurethane material is non-marking, preventing stains on products and maintaining a clean production environment.
For packaging lines, the roller’s grip is critical to maintain product alignment and prevent jams. Our rollers feature a specially formulated surface that offers a coefficient of friction between 0.8 and 1.2 (depending on surface finish), which can be tailored to your specific application. Whether you are handling cardboard boxes, plastic containers, or delicate items, we can adjust the hardness and surface texture to meet your needs.
Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of a polyurethane roller with 80A hardness in a packaging line?
A: Under normal operating conditions (e.g., moderate load, clean environment), the roller can last 2-5 years. The actual lifespan depends on factors such as speed, load, and exposure to chemicals. We recommend regular inspection and lubrication of bearings to maximize longevity. -
Q: Can I get a roller with a different length or diameter?
A: Yes, we offer full customization. You can specify any length up to 3000mm and outer diameter from 30mm to 500mm. Please contact our sales team with your requirements. -
Q: Is the roller compatible with existing conveyor systems?
A: Most standard conveyor systems use a shaft diameter of 20mm or 25mm. We can supply rollers with pre-installed bearings or a hollow shaft to fit your specific mounting. Please provide your shaft dimensions for a perfect fit. -
Q: What is the minimum order quantity (MOQ)?
A: The MOQ is 10 pieces for standard sizes. For custom sizes, MOQ may be higher. We can discuss based on your project scale. -
Q: Do you provide samples before bulk order?
A: Yes, we offer sample pieces at a nominal cost. The sample fee is refundable upon placement of a bulk order. Lead time for samples is typically 5-7 working days. -
Q: Can the roller withstand high temperatures in a packaging line?
A: The standard polyurethane material is rated for continuous use up to 80°C. For higher temperature applications (up to 120°C), we offer a special heat-resistant polyurethane compound. Please specify your temperature requirement. -
Q: Are these rollers suitable for food packaging?
A: Yes, our polyurethane material is food-grade and complies with FDA and EU regulations. We can provide certificates upon request. The rollers are non-toxic and odorless, making them safe for direct contact with packaged food items. -
Q: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects. Warranty covers premature wear, cracking, or delamination. Our after-sales team is available to assist with any issues.
