Henan San Kuang Machinery Technology Co., Ltd. is proud to offer our high-quality Polyurethane Roller for Gravure Printing Press, designed to deliver exceptional performance and durability in demanding industrial environments. With a precision length of 400mm and a hardness of 80 Shore A, this roller is specifically engineered to resist solvents and wear, ensuring consistent ink transfer and minimal downtime. As a trusted manufacturer with a factory spanning 10,000-30,000 square meters and a dedicated team of 51-100 employees, we combine advanced production techniques with rigorous quality control to provide rollers that meet the exacting standards of the printing industry.
Our core value lies in delivering a reliable product that enhances your gravure printing process. The polyurethane material offers excellent elasticity, abrasion resistance, and chemical stability, making it ideal for use with solvent-based inks. Whether you need a replacement roller or a custom solution, our team can tailor the diameter, color, and core material to your specifications.
Key Features & Benefits
- Solvent Resistant: Formulated with premium polyurethane compounds that resist swelling, cracking, and degradation from common gravure solvents (toluene, ethyl acetate, etc.).
- Precision Dimension: 400mm length with tight tolerances (±0.5mm) ensures perfect fit in your press.
- Optimal Hardness: 80 Shore A provides the right balance of surface contact pressure and ink release for sharp, high-quality prints.
- High Durability: Excellent abrasion resistance extends service life, reducing replacement frequency and operational costs.
- Customizable Options: Available in various diameters, colors, and core materials (steel, aluminum, or stainless steel) to match your specific machine requirements.
- Consistent Performance: Precision ground surface finish ensures uniform ink transfer and minimal dot gain.

Our polyurethane roller is manufactured using a precision casting and grinding process that ensures a uniform density and minimal porosity. The 80 Shore A hardness is specifically chosen for gravure printing applications where the roller needs to provide sufficient nip pressure to transfer ink from the engraved cylinder to the substrate while maintaining a soft touch to avoid damaging the cylinder. The solvent resistance is achieved through a proprietary formulation that cross-links the polymer chains, making the material less susceptible to chemical attack. This results in a roller that maintains its dimensional stability and surface properties even after prolonged exposure to aggressive solvents.
The roller's core is typically made of high-strength steel, which is precision-machined to ensure concentricity and balance. For special applications, we offer aluminum or stainless steel cores that are lighter or more corrosion-resistant. Each roller is dynamically balanced to minimize vibration during high-speed operation, which is critical for achieving consistent print quality. The surface is ground to a mirror-like finish (Ra ≤ 0.4 μm) to provide a smooth, even surface that enhances ink release and reduces the risk of streaks or fisheyes.
We understand that every printing press has unique requirements, which is why we offer extensive customization. You can choose from a range of diameters (e.g., 50mm to 150mm), hardness levels (60–95 Shore A), and lengths (up to 2000mm) to match your specific machine. The roller can also be supplied with various end configurations (e.g., threaded, keyed, or with bearing housings) to simplify installation.

Frequently Asked Questions
Q1: Can this roller be used with water-based inks as well?
A: Yes, the polyurethane material is compatible with both solvent-based and water-based inks. However, if you primarily use water-based inks, we recommend a slightly harder durometer (e.g., 85–90 Shore A) for optimal performance. Please consult with our sales team for the best recommendation.
Q2: What is the typical lead time for a custom roller?
A: For standard sizes (400mm length, 80 Shore A), stock items can be shipped within 3–5 working days. Custom orders typically require 10–15 working days, depending on the complexity of the specifications. We prioritize urgent orders upon request.
Q3: How do I know if the roller will fit my gravure press?
A: Please provide the following details: shaft diameter, length, core type (e.g., with keyway, flat, or threaded), and any special mounting requirements. We can also provide a sample drawing for your approval before production.
Q4: What is the maximum temperature the roller can withstand?
A: The standard polyurethane roller can operate continuously at temperatures up to 80°C (176°F). For higher temperature applications (up to 120°C), we offer a heat-resistant variant. Please specify your temperature range when ordering.
Q5: Does the roller require any special maintenance?
A: Regular cleaning with a mild solvent and a soft cloth is recommended to remove ink residue. Avoid using harsh chemicals or abrasive tools that could damage the surface. Store the roller in a cool, dry place away from direct sunlight when not in use.
Q6: Can you provide a sample for testing before bulk order?
A: Yes, we offer sample orders. The sample cost is negotiable, and we can deduct it from the bulk order if you place a quantity order within 60 days. Shipping charges apply.
Q7: Are there any certifications for the roller material?
A: Our polyurethane material is manufactured in accordance with ISO9001:2015 quality standards. We can provide a Material Safety Data Sheet (MSDS) and a certificate of compliance upon request. The roller itself is not subject to specific product certifications, but our factory holds multiple certifications including ISO14000 and OHSAS18001.
