Since the invention of the first self-aligning ball bearing 100 years ago, SKF has gradually evolved into a knowledge-based company and now provides customers with unique solutions in five major areas of technical competence. These areas include bearings, bearing units and seals, but of course extend to other areas including: lubricants and lubrication systems, which play a vital role in the life of bearings in many fields of application; mechatronics, which combines mechanics and electronics Integration of scientific knowledge into systems resulting in more efficient linear motion and sensing systems; and a comprehensive suite of services, from design and logistics support, to condition monitoring and reliability systems. SKF's business is divided into three major divisions: Industrial, Automotive and Service. Each business unit provides services to the global market, focusing on customers and industries relevant to its business. SKF was founded in 1907. From the beginning, it has attached great importance to product quality, technology research and development and market development. The Group invests huge efforts in technological research and product development, continuously obtains various inventions and creations, creates new standards in the field of bearing technology, and introduces new products to the bearing market. Despite this expansion, SKF remains a world leader in the design, production and market development of rolling bearings, as well as in complementary models and products such as seals. SKF has maintained an increasingly important position in the markets for linear motion products, high-precision aerospace bearings, machine tool spindles and equipment maintenance services.
