In 1910, CR Company developed oil seals for Ford Motor Company in the United States. In 1928, CR Company obtained the first oil seal patent. In 1940, CR Company applied synthetic rubber technology to the production of seals for the first time. , ...now, CR Seals is the world's leading manufacturer of seals. In the early twentieth century, CR worked closely with Henry Ford and other automotive pioneers to produce cowhide seals for use in early automobiles. In 1928, CR Company applied for the first patented product of self-contained shaft seals for the design of automotive wheel seals. In the mid-1930s, CR pioneered the development of specially formulated vulcanizable rubber (synthetic rubber) for high-quality seals Material. This development has led to innovations in production processes, new sealing technologies, and expanded industrial applications. Today, CR is the world's leading supplier of seals used in fluid-tight installations in industries such as trucks, automobiles, agricultural machinery and process tools. CR also manufactures sealing products for the aerospace sector, construction machinery, household appliances and various types of pumps, hydraulic systems, motors and related accessories. CR can provide more than 3000 individually designed seals with more than 25000 different lip materials and sizes from 3.2mm to 4572mm (0.125inch to 180inch). These basic varieties include metal clad, all rubber and fabricated the design of. CR is constantly working on research in sealing technology. To improve product performance and reliability. CR has been part of the SKF Group since 1990. SKF is a multinational company with a leading reputation in the field of rolling bearing technology. This organic combination of bearings and seals has laid a solid foundation for the company's innovative design and market development.
