According to the different nature of friction of moving parts

Bearings ("Bearing", Japan is called "Axis subject") is in the process of mechanical transmission fixed and reduce the load coefficient of friction components. Can also say that when the other parts in the shaft relative motion, used to reduce friction during power transmission coefficient and holding shaft center position fixed parts. wheel bearing  re one kind of modern machinery and equipment vital components. Its main function is to support the mechanical rotating body, the drive device for reducing the mechanical load during the friction coefficient. According to the different nature of friction of moving parts, rolling bearings and plain bearings can be divided into two categories.
China is the world's one of the countries bearing the earlier invention, in the Chinese classics, with regard to axle bearing structure has long been documented. Seen from archaeological artifacts and data, China's oldest prototype of modern rolling bearing structure, appeared in 221 BC - 207 BC (Qin) is now Shanxi Yongji County Xue Cliff Village. After the founding of New China, especially since the seventies of last century, a strong push forward reform and opening up, the bearing industry has entered a new period of rapid development of high quality.
In the seventeenth century, the British C. Vallotton design and manufacture of ball bearings and mounted in the car trial and the UK postal P. Wirth made ball bearings of the patent. Eighteenth century German publication on ball bearings HR Hertz contact stress papers. Build on the achievements in hertz, Germany R. 施特里贝克, Sweden A. Pam Glenn, who conducted a number of experiments, the development of the theory and design of rolling bearing fatigue life calculations made contributions. Subsequently, the Russian NP Petrov applying Newton's law of viscosity calculated bearing friction.
Thor O. Renault UK conducted a mathematical analysis of the findings derived Reynolds equation, then laid the hydrodynamic lubrication theory. The early form of linear motion bearings, is a row in the skid plate placed under a row of wood. This technique may be traced back to when the construction of the Great Pyramid of Giza, although there is no clear evidence. Modern linear motion bearings using the same kind of works, but sometimes with the ball instead of rollers. The earliest sliding and rolling element bearings are made of wood. Ceramics, sapphire or glass are also used, steel, copper, other metals, plastics (such as nylon, bakelite, Teflon and UHMWPE) have been widely used.
Axles and heavy-duty trucks from spindle to precision watch parts, many occasions require rotating bearings. The simplest rotary bearing sleeve bearings, it's just a clip between the wheel and axle bushing. This design was subsequently replaced bearings, is a lot of cylindrical roller replace the original bushings, each rolling body is like a single wheel. The earliest practical input of rolling bearings with cage are clockmaker John Harrison in 1760 for the production of H3 Chronographs invented.
Nano lake in Italy discovered a Roman vessel, discovered early examples of ball bearings. This wooden ball bearings are used to support the rotating desktop. The ship was built in 40 BC. It is said that Leonardo da Vinci in 1500 for one kind of ball bearings about once been described. Ball bearing a variety of immature factors, there is a very important point is that the collision will occur between the ball, causing additional friction. But you can put the ball in a small cage to prevent this phenomenon.

This shaft washer with flat bearing more popular

Bi-directional thrust tapered roller bearings are mainly in the steel rolling machine with multi-row cylindrical roller bearings used together. This shaft washer with flat bearing more popular, because this
??Bi-directional thrust tapered roller bearing manufacturer
Bearings can withstand the shaft relative to the bearing housing bore slightly eccentric, as well as radial bearings radial internal clearance slightly. In the two bearing housing seat is equipped with an interval between sets. Spacers size makes roller bearing box cover screw is fully tightened, but bearing no special spring adjustment.
Shaft and housing seat with conical raceway bidirectional tapered roller thrust bearings. Generally lower than with the axes of the plane of the bearing seat with high axial load bearing capacity, and to a certain extent, radial positioning of the shaft. If we consider the desired service life, this bearing load carrying capacity is insufficient, you can use the contact angle of TDIS designed double row tapered roller bearings, see "double row tapered roller bearings."Since Bi-directional thrust tapered roller bearings are usually in the roll journal and roller bearing housing to loosely fitted, most bearing shaft seat one or two locating slots. This makes it possible to use embedded positioning groove key or similar means to prevent rotation of the shaft axis seat.Screw-down bearings - Thrust Tapered Roller Bearings
Third, this type of thrust tapered roller bearings must be able to withstand enormous axial load, and allows the threaded shaft angular displacement relative to the support. Therefore, these wheel bearing usually full roller type, with large diameter and long rollers. In order to withstand the roll offset in the bearing housing on the bearing not adversely affect the performance of this bearing has a spherical seat. The seat can be a shaft or bearing seat box seat.
In the spherical shaft seat and the corresponding concave spherical threaded shaft or pressure roller between the baffle set above a spherical seat of the bearing axis, will produce the necessary right of offset. LYTBZ can also supply the pressure plate.
Spherical bearing box seat when the offset from the bearing housing on the seat between the baffle and the pressure roller groups to bear. This bearing pressure plate is usually supplied with the same bearing.
LYTBZ produce a variety of designs screw bearings; This bearing is customized to meet the special requirements of a particular application
