As a dedicated manufacturer with over 10,000 square meters of production space and a team of 51-100 skilled professionals, Henan San Kuang Machinery Technology Co., Ltd. brings you the Anti-Static Polyurethane Roller specifically engineered for high-precision printing machines. With dimensions of 100mm Outer Diameter, 20mm Bore, and 10mm Wall Thickness, this roller delivers reliable static dissipation and consistent performance. Our commitment to quality is backed by multiple management system certifications, ensuring that every roller meets rigorous industrial standards for durability and functionality.
This roller is designed to eliminate static electricity buildup during the printing process, which can cause ink smudging, paper jams, and equipment damage. The polyurethane material offers excellent abrasion resistance, chemical stability, and load-bearing capacity, making it ideal for continuous operation in high-speed printing environments. The precision-machined bore ensures a snug fit on shafts, while the uniform wall thickness guarantees balanced rotation and minimal vibration.
Key Features & Technical Specifications
- Anti-Static Property: Surface resistivity below 10^6 Ω/sq effectively dissipates static charges, protecting sensitive electronic components and improving print quality.
- Premium Polyurethane Material: High tear strength, oil resistance, and ozone resistance extend service life even in harsh environments.
- Precision Dimensions: Outer diameter tolerance ±0.1mm, bore tolerance ±0.05mm, wall thickness uniformity within 0.2mm.
- Customizable Hardness: Available in Shore A 60-95 to suit different nip pressure and substrate requirements.
- Low Compression Set: Maintains shape under continuous load, reducing downtime for replacement.
- Wide Operating Temperature Range: -20°C to +80°C, suitable for both cold and hot printing processes.

Benefits for Your Printing Operations:
By integrating this anti-static roller into your printing machine, you can significantly reduce static-related defects such as ghosting, misregistration, and ink splatter. The roller’s uniform wall thickness ensures consistent pressure distribution across the web, leading to sharper images and more uniform ink transfer. Additionally, the polyurethane composition resists wear from continuous contact with inks, solvents, and cleaning agents, decreasing the frequency of roller replacement and maintenance downtime.
The 20mm bore is designed to fit standard shafts used in many printing presses, and the 10mm wall thickness provides adequate cushioning for delicate substrates without compromising rigidity. Whether you are running high-speed flexographic, gravure, or offset printing, this roller delivers reliable performance, reducing waste and improving overall production efficiency.

Frequently Asked Questions
-
Q: Can this roller be used in solvent-based ink systems?
A: Yes, the polyurethane material is resistant to many common solvents and inks. However, for aggressive chemicals, we recommend consulting our technical team to confirm compatibility. -
Q: Is the bore keyway or spline included?
A: The standard bore is a straight cylindrical hole. Custom keyways, splines, or threaded holes can be machined upon request, please specify when ordering. -
Q: What is the typical lead time for this roller?
A: For standard dimensions, lead time is approximately 15-20 working days. Custom orders may require additional time depending on complexity. -
Q: How do I verify the anti-static property of the roller?
A: We provide a surface resistivity test report with each shipment. The roller’s surface resistivity is guaranteed to be less than 10^6 Ω/sq. -
Q: Can the roller be used in food packaging printing?
A: Yes, our polyurethane formulation can be adapted to meet food contact regulations (such as FDA or EU standards). Please contact us with your specific requirements. -
Q: What is the maximum operating speed for this roller?
A: The roller is designed for speeds up to 300 m/min under normal conditions. Higher speeds may require dynamic balancing, which is available as an optional service. -
Q: Do you offer a warranty?
A: Yes, we provide a 12-month warranty against manufacturing defects. This includes dimensional accuracy, surface defects, and material delamination under normal use. -
Q: How should I store the roller if not used immediately?
A: Store in a cool, dry place away from direct sunlight, ozone, and strong chemicals. Keep the roller wrapped in a protective cover to prevent surface contamination.
