Since the invention of the first self-aligning ball bearing 100 years ago, SKF has gradually evolved into a knowledge-based company that now provides customers with unique solutions in five 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 bearing life in numerous application areas; mechatronics, which combines mechanics and electronics Knowledge is integrated into the system, resulting in a more efficient linear motion and sensing system; and a complete set of services, from design and logistics support, to condition monitoring and reliability systems. SKF’s business is divided into three divisions: Industry, Automotive and Services. Each business unit serves global markets, focusing on customers and industries relevant to its own business. SKF was established in 1907 and has attached great importance to product quality, technology development and market development from the very beginning. The Group has invested huge efforts in technical research and product development, and has continuously obtained various inventions and creations, set new standards in the field of bearing technology, and introduced new products to the bearing market. Despite this expanded range, SKF maintains world leadership in the design, production and market development of rolling bearings, as well as in complementary models, products such as seals. SKF has maintained an increasingly important position in the market for linear motion products, high-precision aerospace bearings, machine tool spindles and equipment maintenance services.
