No, there are many kinds of bearings, and the inventor of each bearing is different. For example, the brand FAG is also inspired by a genius. As early as 1883, in the German town of Schweinford, Friedrich Fischer designed a special steel ball grinder, which made it possible to produce completely spherical steel balls by grinding technology for the first time. This invention is regarded as the cornerstone of the rolling bearing industry. SKF Group, headquartered in Gothenburg, Sweden, is a leader in bearing technology and manufacturing. Sven Wingquist invented double-row self-aligning ball bearings in 1905, and then established Swedish ball bearing manufacturing company Svenska Kullargerfabriken, referred to as SKF in 1907. 1895, Mr. Henry Timken, the founder of Timken Timken Company, invented the tapered roller bearing for axle at that time, that is, tapered roller bearing, and the company was established. These are the three most famous bearing factories in the world. In the early form of linear motion bearing, a row of wooden sticks were placed under the pry plate. This technology may be traced back to the construction in great pyramid of giza, although there is no clear evidence. Modern linear motion bearings use a working principle, but sometimes balls are used instead of rollers. The earliest sliding bearings and rolling bearings were made of wood. Ceramics, sapphires or glass are also used, and steel, copper, other metals and plastics (such as nylon, phenolic plastics, Teflon and UHMWPE) are widely used. From heavy-duty wheel shafts and machine tool spindles to precision clock parts, rotary bearings are needed in many occasions. The simplest rotary bearing is a sleeve bearing, which is just a bushing sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, that is, many cylindrical rollers were used instead of the original bushings, and each roller was like an independent wheel. The earliest practical rolling bearing with cage was invented by watchmaker john harrison in 1760 for making H3 chronograph. An early example of ball bearing was found on an ancient Roman ship found in Lake Nano, Italy. This wooden ball bearing is used to support the rotating table top. The ship was built in 40 BC. It is said that Leonardo da Vinci once described a ball bearing with a ratio of 1500. Among all kinds of immature factors of ball bearings, it is very important that the balls will collide and produce extra friction. But putting the ball in a small cage can prevent this phenomenon. /kloc-in the 0/7th century, Galileo first described the "fixed ball" or "cage ball" ball bearing. But after a long time, it was not realized to install bearings on the machine. The first patent on fairway was obtained by Philip Vaughan of Carmarthen in 1794. In 1883, Friedrich Fisher put forward the idea of using a suitable production machine to grind steel balls with the same size and accurate roundness. This laid the foundation for establishing an independent bearing industry. "Gu? The original combination "stahlkugelfabrik" or "Fischer Aktien-Gesellschaft" later became a trademark, registered on July 29th, 1905. 1962, the trademark FAG was modified and still used today, and it became an inseparable part of the company in 1979.
