SKF launched a new range of hydraulic seals to meet the hydraulic cylinders industry's needs for improved performance. The launch introduces new product in the range, like S1S polyurethane U-cup for heavy duty rod sealing systems and three new styles of polyurethane piston seals. The new complete SKF hydraulic seals range includes thousands of standard articles from more than forty different designs of rod seals, piston seals, wipers, static seals and guide rings, plus a broad range of design and material choices for tailor-made solutions. The hydraulic sealing solutions provide designers with the complete sealing and guiding system to develop a wide variety of hydraulic cylinders. The system approach, including SKF knowledge and guidance for system design and specification, enables hydraulic cylinder producers to improve system performance for the different challenging environments that hydraulic cylinders face. The new solution can also serve existing applications with replacement parts. The design and development of material, product and process, combined with testing and failure analysis, are vital elements for successful seal development and good performance. SKF combines these elements with its expertise in various applications, to offer solutions that are based on an understanding of sealing systems under real conditions.
