Henan San Kuang Machinery Technology Co., Ltd. is a professional manufacturer specializing in high-performance polyurethane rollers for paper processing machines. Our Polyurethane Roller, 60mm Diameter, 85 Shore A, Non-Marking is engineered to deliver exceptional durability, precise grip, and zero residue transfer, making it an ideal choice for demanding paper converting and printing applications. With a factory spanning 10,000–30,000 square meters and a dedicated team of 51–100 employees, we combine advanced manufacturing capabilities with rigorous quality control to ensure every roller meets the highest industry standards.
This roller is specifically designed to provide consistent performance in paper processing environments where marking or contamination must be avoided. The non-marking polyurethane formulation ensures that delicate paper surfaces remain pristine, while the 85 Shore A hardness offers an optimal balance between flexibility and load-bearing capacity. Whether used in laminating, coating, embossing, or conveying systems, our roller minimizes downtime and extends service life.
Key Features & Technical Specifications

Frequently Asked Questions
-
Q: Can this roller be used on high-speed paper converting machines?
A: Yes, the 85 Shore A hardness and balanced dynamic properties allow stable operation at speeds up to 500 m/min. For higher speeds, we recommend a custom dynamic balancing service. -
Q: Is the roller resistant to common printing inks and solvents?
A: Yes, our polyurethane formulation is resistant to aliphatic hydrocarbons, alcohols, and mild acids. For aggressive solvents, please consult our technical team for a customized compound. -
Q: What is the typical lead time for standard 60mm diameter rollers?
A: For standard sizes (60mm diameter, lengths up to 2000mm), lead time is 7–10 working days. Custom specifications may require 15–20 working days. -
Q: Can you provide a different surface finish, such as grooved or textured?
A: Absolutely. We offer smooth, matt, grooved, and spiral finishes. Surface roughness can be tailored to your application (Ra 0.4–6.3 μm). -
Q: How do you ensure the non-marking property is consistent across batches?
A: We perform a 100% wipe test on each roller using white paper under controlled pressure. Only rollers with zero visible transfer are shipped. -
Q: What is the minimum order quantity (MOQ) for this product?
A: MOQ is 1 piece for sample orders, and 10 pieces for bulk production. Custom colors and sizes may have higher MOQ. -
Q: Do you offer a warranty on your polyurethane rollers?
A: Yes, we provide a 12-month warranty against manufacturing defects, including delamination, improper hardness, or dimensional deviation. -
Q: Can the roller core be made of stainless steel or other materials?
A: Yes, we offer steel, aluminum, and stainless steel cores. Please specify your requirement when ordering.
