PU Coating: Steel with PU, Bearing with PU, Plastic with PU, and Rubber Coated Roller Types: PU Roller, Rubber Roller Liner Options: Grinding Machine Inner Liner, Tube Inner Liner Polyurethane rollers are known for their high strength, compressive resistance, wear resistance, oil and corrosion resistance, and strong adhesion without delamination. These versatile components are widely used in industries such as metallurgy, paper, coal, wood processing, chemical fiber, textiles, and printing. (1) **Metallurgy Rollers**: Typically made of CPU (Cast Polyurethane), these rollers are ideal for harsh environments where high performance is required. Examples include pinch rollers, tension rollers, pressure rollers, transfer rollers, and guide rollers. Cold rollers are a type of hard rubber roller with a Shore A hardness of 90 ± 5, tensile strength over 40 MPa, elongation over 400%, and peel strength on steel shafts exceeding 500 kN/m. Tension rollers can be as large as φ1.5–1.7m in diameter and up to 2m in length, with a plastic thickness of 20mm. Color thin rollers are used in stainless steel painting, requiring not only wear resistance but also corrosion resistance and elasticity for even and smooth printing (normal hardness: Shore A 40–60). (2) **Printing Rollers**: Include letterpress printing rollers (Shore A 20–30), offset printing rubber rollers (Shore A 38–45), and high-speed printing rollers. The low hardness, high strength, and excellent elasticity of polyurethane make it ideal for high-speed, low-hardness printing applications. (3) **Rice Hulling Rollers**: Polyurethane replaces traditional rubber rollers, increasing service life by 3–4 times while maintaining food safety and hygiene. (4) **Paper Industry Rollers**: These rollers improve production efficiency by at least 100%, reduce energy consumption, and lower overall costs. (5) **Textile Rollers**: Used in pelletizing, drawing, and drafting processes, they significantly extend the lifespan of the equipment. With a wide range of applications and superior performance characteristics, our polyurethane rollers are a reliable choice for industrial use. Whether you need custom-shaped gaskets or specialized sealing solutions, we offer tailored options to meet your specific needs.
