Double row tapered roller bearing structure is different, the most is a lot of type 35000, outer ring and two inner ring have double track, between two inner ring baffle, change the thickness of the flap can adjust the clearance. Tapered roller bearings can withstand axial load in a direction that can limit the shaft or the axial displacement of the housing in one direction. This type of bearings in bear radial load at the same time can carry two-way axial load, the bearing axial clearance range can limit shaft and the shell axial displacement. Compared with the angular contact ball bearing, bearing capacity is big, limit rotational speed is low. Tapered roller bearing is mainly used to bear mainly consisting of radial load and axial load. The structure characteristics of tapered roller bearing. Tapered roller bearing type code 30000, tapered roller bearing for separating type bearing.


Deep groove ball bearing structure of each ring cross section is about the equatorial circumference of the ball for a third consecutive water groove type. Deep groove ball bearing is mainly used to bear radial load, can also carry a certain amount of axial load. When bearing radial clearance increases, the performance of angular contact ball bearing, can carry alternating axial load in two directions. Deep groove ball bearing has simple structure, easy to use, is the production batch, the most widely application scope biggest import bearings. Compared with other types of bearing the same size, such bearing small friction coefficient, extreme high speed, high accuracy, is the first choice for a user to select type of bearing.


An early form of linear motion bearings, pry plate on the next line a line of bar. This technique may can be traced back to build the great pyramid of giza, although there is no clear evidence. Using modern working principle of the linear motion bearings, but sometimes a ball rather than roll.


In 1883, friedrich fisher put forward using the appropriate production machinery of the same size and roundness steel ball precision. Decided to "fisher Automatische gu stahlkugelfabrik" or "fisher Aktien legal society" - the first letter of later became a trademark, registered in July 29, 1905. In 1962, gay this logo, we use today, and an integral part of the company in 1979. This creates a separate bearing industry laid a solid foundation.


Nano in Rome, Italy found a lake boat, found early example of ball bearing. Wooden ball bearing used in support of the rotary table. The first ball is patent tracking card masson Philip comedian in 1794. But in the future for a long time, didn't realize the bearing installed on the machine. The ship was built 40 years BC. But you can put the ball in a small cage to prevent this phenomenon. Immature factors of ball bearing, it is important to ball collided, causing additional friction. Galileo in the 17th century, "fixed", or "cage" ball bearings to do first. Leonardo Da Vinci is thought to be around 1500 in the ball bearing are described.


From overloading car wheel and shaft precision clock parts, many occasions require rotary bearing. The design of rolling bearing, is to use a lot of roller bushing, but each roller. The earliest to the actual rolling bearing retainer was invented the clockmaker John harrison let H3 time plan in 1760. The rotation of the bearing sleeve bearing is the most simple, it's just a shaft sleeve SKF Bearing WebSite http://www.skf-fag.org/ .


In 1907, SKF bearing factory sven WenKuiSi design since the first modern spherical ball bearing.


The earliest of sliding and rolling bearing is made of wood. Ceramic or glass, sapphire, also have use, steel, copper and other metals, plastics, nylon, bakelite, fluoride lung and UHMWPE) has been widely used.


In 1895, Henry iron will design the first tapered roller bearing, and set a timken company patented three years later.
