SKF, Svenska Kullagerfabriken AB (Swedish: Swedish ball bearing factory AB), later AB SKF, is a leading bearing and seals manufacturing company founded in Gothenburg, Sweden in 1907. The company manufactures and supplies bearings, seals, lubrication and lubrication systems, maintenance products, mechatronics products, power transmission products, condition monitoring systems  and related services globally.
Today, SKF is the largest bearing manufacturer in the world and employs approximately 48,600 people in 140 production and manufacturing sites, which in addition to 15,000 worldwide distribution locations encompasses 130 countries worldwide. With an annual Turnover of SEK 70.975 Billion, and total assets of SEK 81.639 Billion in FY2014, SKF has been listed as one of the largest companies in Sweden and among largest public companies in the world according to Forbes Global 2000 ranking. 
Sven Wingqvist, at the time a thirty-year-old plant engineer responsible for repairs and maintenance at Gamlestadens Fabriker, was dissatisfied with the performance of the ball bearings then in use. These were rigid ball bearings, imported from Germany, and if the long shafts on the machinery in a textile mill were the least bit misaligned, the ball bearings would become overheated and break down, bringing production to a costly halt. In spring 1907, Wingquist presented a breakthrough – a double row self-aligning ball bearing with a spherical raceway in the outer ring, shared by both rows of balls. This allowed the inner ring to align freely in relation to the outer ring, with no negative impact on the function of the bearing. The new bearing solved the problem associated with misalignment of the shafts and thus did away with the frequent production stops. Self-alignment was particularly useful in the less-than-perfect machinery of the times and in buildings with subsidence problems, which was the case at Gamlestadens Fabriker, since much of the land on which Göteborg has been built is clay.
The company was founded on 16 February 1907 on Sven Wingqvist's Swedish patent No. 25406, a multi-row self-aligning radial ball bearing. The Patent was granted on 6 June in Sweden coinciding with patents in 10 other countries. The new ball bearing was successful from the outset. By 1910, the company had 325 employees and a subsidiary in the United Kingdom. Manufacturing operations were later established in multiple countries.
SKF began its operations in India in 1923 by establishing a trading outpost in Calcutta. The early operations involved importing of automotive bearings. SKF India Ltd was incorporated in 1961 following a collaboration between AB SKF, Associated Bearing Co. Ltd and Investment Corp. of India Ltd. In 1963, SKF set up its first bearing factory in Pune, Maharashtra.
Assar Gabrielsson, SKF sales manager and Björn Prytz, Managing Director of SKF were the founders of Volvo AB in 1926. In the beginning, the company functioned as a subsidiary automobile company within the SKF group. SKF funded the production run of the first thousand cars, built at Hisingen in Gothenburg, beginning in 1927. SKF used one of the company's trademarked names: AB Volvo, which derives from the Latin "I roll", with its obvious connotations of bearings in motion. The ownership of Volvo lasted until 1935 when the last shares were divested.
In the 1970s SKF embarked on a massive production rationalization program in Europe. A visionary project, "Production Concept for the 80s" was launched with the aim to run the night shifts practically unmanned. To increase productivity and safeguard the product quality, a continuous, automatic flow of bearing rings was needed, so SKF developed the Flexlink brand. FlexLink created the multiflex plastic chain conveyor system to solve the business requirements. SKF divested FlexLink as a separate company in 1997.
Present day business
The SKF Group currently consists of approximately 150 companies including the seal manufacturer Chicago Rawhide. Since its founding, SKF's company headquarters have been located in Gothenburg. One recent acquisition was that of Economos, part of Salzer Holding, an Austria-based seal company, Jaeger Industrial and ABBA, Taiwanese manufacturers of linear actuators. The company's clients include General Electric, Rolls-Royce plc and Pratt & Whitney. It also supplies bearings for Ferrari racing vehicles, used in Formula One races, and is a sponsor of F1. Another focus area is the energy sector, including wind turbines which generate electricity.
By 2013, SKF Industrial Market, Regional Sales and Services, made up about 40% of SKF's total sales.
SKF sells products within five technology platforms:
- Bearings and Units
- Lubrication Systems
SKF and Business Excellence
SKF runs its own business excellence program for continuous improvement of its business processes in all parts of the company. The program is based on previous initiatives like TQM and integrates with lean management also statistical methods of Six Sigma along with related project management. Many elements of this SKF program remind of the integrated approach of the actual EFQM model for Business Excellence.
The Group has global certification to IS0 14001 (environmental management system), ISO 50001 (energy management) and OHSAS 18001 (health and safety) standards. Its operations are also certified to either ISO 9001 or applicable customer industry standards, e.g. ISO/TS 16949 (automotive), AS9100 (aviation) or IRIS (railway) for quality management systems.
