Bearings have played a key role in the history of mechanical skills. Although the era of roller bearing can be traced back to the Middle Ages, Swedish creator and industrialist Sven Wingquist (1876-1953) Recognized as the creator of modern roller bearings. In 1907; he created spherical roller bearings. Swedish industry, uniquely by the Swedish bearing company (Svenska Kullager Fabriken) played an important role in the development of rolling roller bearings. Sweden The bearing company was founded by Winquist; it is referred to as SKF in the international market.
The railway and tram skills pioneered the use of bearings for the broad Liuhe. In 1923; the Swedish National Railways used spherical roller bearings and radial roller bearings for the first time on the train.
The most commonly used spherical roller bearing chamber C-type bearing for C-type bearings; created by SFK's Arvid Palmgren in 1948. Unlike the earlier bearings; C-type bearings have symmetry Roller; the thickness of the two ends is the same. In addition; the non-fixed bearing seat or retaining frame can keep the roller in the correct running track.
One advantage of the C-type bearing is that it can accept the axial torque generated by similar cars during cornering. When accepting axial torque; the C-type bearing with symmetrical rollers can guarantee that all roller bearings receive the same load; It will move axially toward the inner ring. It is different from the fixed bearing seat of the old one; the loose bearing seat can move with the roller; then the bearing does not add pressure or friction at both ends of the roller when receiving the axial torque Because of the above characteristics; C-type bearings can accept a larger load than the earlier bearings; in the case of distortion, it is not an exception.
The CC type bearing CC type bearing is a self-aligning roller bearing. This bearing can significantly reduce the friction of the flange side; it is by the engineers of Gothenburg SKF company Magnus Kelstrom and Leif Bleu Mquist created the .CC bearing in 1972 to reduce the friction on a small spread area; then lowers the operating temperature of the bearing. This type of bearing does not need to be often smooth; the speed is faster and the service life is longer.
Shaftless axles in 1972; SKF has introduced a new automotive axle bearing. This axle bearing created by Sture Aberg does not require the use of a shaft; it is composed of double row angular contact bearings; For the front wheel drive of the car. The shaftless bearing is not only low in its own cost; it can also reduce the cost of assembling the car.
ARBTM bearing CARBTM bearing chamber Magnus Kelstrom created a new type of roller bearing. It is linked to the strengths of other types of bearings; it can accept greater axial loads and lateral thrust; Very high carrying capacity.
