The Gallus Ceramic Sleeve is a premium, precision-engineered component specifically designed for Bobst printing machines, crafted from high-grade special alloy material to redefine performance in the printing industry. This ceramic sleeve stands out as a reliable choice for businesses seeking durability, efficiency, and cost-effectiveness, combining advanced materials with cutting-edge manufacturing techniques. Whether for high-volume production or specialized printing tasks, the Gallus Ceramic Sleeve delivers consistent results, thanks to its wear-resistant, corrosion-resistant, and high-temperature resistant properties. It is engineered to minimize downtime, reduce maintenance costs, and enhance ink transfer efficiency—making it an indispensable asset for modern printing operations.
Built with a special pure chromium oxide (Cr₂O₃) surface layer (formulated from imported ceramic powder with ultra-fine particles), the Gallus Ceramic Sleeve boasts an impressive coating hardness of HV1400. This robust construction ensures exceptional resistance to wear, corrosion, and high temperatures, even in demanding printing environments. Unlike standard sleeves that degrade quickly under heavy use, this ceramic sleeve maintains structural integrity over time, eliminating frequent replacements and reducing operational disruptions.
Equipped with ALE fiber laser engraving technology, the Gallus Ceramic Sleeve features smooth mesh walls, a flat mesh bottom, and optimized pore structure. These design elements maximize ink transfer capacity, ensuring sharp, consistent prints with every run. Additionally, the laser-engraved surface enables rapid ink dilution and effortless cleaning—saving valuable time during setup and maintenance. Print shops can boost productivity by minimizing downtime spent on cleaning and retooling, while achieving professional-quality results.
The Gallus Ceramic Sleeve undergoes a strict ceramic layer plasma spraying process, which guarantees unparalleled porosity (1～2%), thickness consistency, and coating uniformity. This precision engineering supports engraving up to 2000 L/in mesh, making it suitable for high-definition printing applications. With a runout of 0.005～0.01 mm and cylindricity of 0.01 mm, the sleeve delivers micron-level precision, ensuring stable operation and eliminating print defects caused by uneven surfaces or misalignment.
By combining a nickel-chromium alloy underlayer (for enhanced bonding between the base roller and ceramic coating) and imported Cr₂O₃ powder, the Gallus Ceramic Sleeve achieves a bonding strength of 40—60 Mpa. This durable construction extends the product’s service life, reducing the frequency of replacements and lowering long-term operational costs. Print businesses can invest confidently, knowing this ceramic sleeve offers a high return on investment through improved efficiency, reduced maintenance, and consistent performance.

The Gallus Ceramic Sleeve leverages state-of-the-art ALE fiber laser engraving to create highly precise mesh structures. This advanced process ensures smooth mesh walls, flat mesh bottoms, and consistent pore sizes—critical for optimizing ink transfer and print quality. Unlike traditional engraving methods, fiber laser technology delivers exceptional accuracy, enabling customization of mesh shapes and angles to meet specific printing needs.
To achieve a uniform, high-performance ceramic coating, the sleeve undergoes a rigorous plasma spraying process. This technique controls the coating’s porosity, thickness, and adhesion, ensuring it bonds securely to the nickel-chromium alloy underlayer. The result is a durable, wear-resistant surface that withstands harsh printing conditions while maintaining precision and consistency.
Every Gallus Ceramic Sleeve uses imported ceramic powder with smaller particles for the Cr₂O₃ surface layer, enhancing wear resistance and service life. The nickel-chromium alloy underlayer is selected for its superior bonding properties, ensuring the ceramic coating adheres firmly to the base roller—preventing chipping or peeling even under heavy use.
The Gallus Ceramic Sleeve is specifically engineered for Bobst printing machines, making it a perfect replacement or upgrade part for these industry-leading devices. It is ideal for a wide range of printing applications, including label printing, packaging printing, and flexible packaging production—where precision, durability, and ink efficiency are critical.
Beyond Bobst machines, the sleeve supports customized mesh designs (shapes, angles) and specifications, making it compatible with other printing equipment based on client needs. Whether you require hexagonal mesh holes, square concave-convex dots, or a specific arrangement angle (30°, 45°, 60°, etc.), our team can tailor the Gallus Ceramic Sleeve to match your unique production requirements.
