SKF invented the first self-aligning ball bearing in 1907, and is now a market leader in bearing technologies. Ball bearings rely on sphere-shaped elements arranged in rows to carry loads and conduct motion. They are ideally suited for applications requiring low frictional resistance, high speed capabilities, low maintenance and long life. For more than 100 years, the world's engineers, technicians and mechanics have turned to SKF for the best possible solutions. Available for a wide range of applications and needs, SKF bearings and seals are designed and manufactured to the highest quality standards, ensuring long life and safety.
