Classification of Bearing:

No	Name	Brief introduction
1	Deep groove ball bearings	Can withstand the radial load and the bidirectional axial load, applied to high speed and low noise, low vibration.
2	Angular contact ball bearings	Contact angles between rings and balls, standard contact angle of 15 °, 30 ° or 40 ° contact angle and axial load carrying capacity is larger the contact angle as small as possible to high speed rotation
3	Four-point contact ball bearing	Can withstand the radial load and the bidirectional axial load bearing ,also can replace a positive combination or combinations of angular contact ball bearings are suitable for back subjected to purely axial load, or axial load component synthesis of large loads
4	Self-aligning ball bearings	For the Raceway surface of sphere, aligning performance, so it can be automatically adjusted by deflection of the shaft or housing or are not one caused by misalignment of axis, bearings with a tapered bore through the use of fasteners can be easily mounted on the shaft.
5	Cylindrical roller bearings	Cylindrical roller and the Raceway in a line contact, large radial load capacity, shall apply to withstand heavy loads and shock loads, also apply to high speed rotation.
6	Entity-type needle roller bearings	Inner ring of the bearing with NU-type cylindrical roller bearing of the same basic structure, but as a result of needle volume can be reduced, and can withstand high radial load bearings without inner ring mounting surfaces with appropriate precision and hardness of the shaft used as a Raceway.
7	Tapered roller bearings	The bearings are fitted with cone-shaped roller, roller cone large rib-led design makes the inner ring and outer ring raceway of Raceway surface and roller surface of the cone intersects the surface vertex in the Center bearing the single row bearing may withstand the radial load and the axial load, double row bearing may withstand the radial load and the bidirectional axial load
8	Self-aligning roller bearing	The class bearing in spherical rolled road outer ring and double rolled road within circle Zhijian with spherical rolled child, by internal structure of different, is divided into r, and RH, and RHA and SR four species type type, due to outer ring rolled road of arc center and bearing Center consistent, has adjustable heart performance, so can automatically adjustment due to axis or shell of Flex or not concentric caused of axis not are can bear radial load and two-way axis to load. In particular, large radial load capacity, suitable for heavy loads and impact loads
9	Thrust ball bearings	Raceway washers roller ring and ball and cage components compatible with the shaft Raceway circle called a shaft washer, Raceway laps in conjunction with shell called a seat. Double direction bearings are in the ring a secret shaft combined with single direction bearings can accommodate axial loads, double direction bearings can support bidirectional axial load
10	Cylindrical roller thrust bearings	By washer-roller ring (shaft washer, housing washer) and cylindrical roller and cage assemblies constitute. Cylindrical roller crowning, so between the roller and the Raceway surface uniformity can sustain axial load axial load capacity, strong axial rigidity
11	Thrust needle roller bearings	Separable bearings from roller and needle roller and cage assemblies constitute, and stamping of thin-ring raceway (w) or for cutting process of thick steel-roller ring (WS) any combination of non-separable bearings are made of precision stamping process for the roller and needle roller and cage assemblies constitute the whole bearing.
12	Thrust tapered roller bearings	The class bearing with round Taiwan shaped rolled child (big endian for spherical), rolled child by rolled Road circle (axis circle, and seat circle) block side accurate guide design Shang makes axis circle and seat circle rolled road surface and rolled child scroll surface of each cone surface of vertex intersect Yu bearing center line Shang of point, one-way bearing can bear one-way axis to load, two-way bearing can bear two-way axis to load.
13	Thrust spherical roller bearing	The bearings are arranged in spherical roller tilt, due to ring raceway surface of sphere, with self-aligning properties, so you can allow the tilt axis has a number of axial load carrying capacity is very large, to withstand axial loads and can also withstand some radial loads, can be used with lubricants.

Bearing draft picture:

Working principle of bearing:

1.Bearings are developed on the basis of rolling bearing and its working principle is based on the rolling friction instead of sliding friction, generally consisting of two rings, consisting of a group of rolling elements and cage's versatility is very strong, a high level of standardization and serialization of machine components. Due to various mechanical has different working conditions, on bearing load capacity, structure and performance, and so have put forward a variety of different requirements. For this reason, rolling bearing having a wide range of structures. However, the basic structure is composed of an inner ring, outer ring, rolling elements and cage – often referred to as the four pieces.

2.For sealed bearings, plus lubricants and sealing ring (or shields) – also known as the six major purchases. Is based on the rolling elements bearing the name type name for the corresponding name. Role of various parts in the bearings are: for radial bearings, the inner ring and shaft usually a tight fit, and working together with the axis, usually associated with bearings or mechanical shell holes in the outer ring transition fit, plays a supporting role. However, in some cases, also operate in the outer ring, fixed play a supporting role or the inner ring on the inner ring and outer ring are running simultaneously.

3. Thrust bearing, tight fit sports with that axis and axis, and transition into shell holes in housings or mechanical work and plays a supporting role as a seat. Roller (ball, roller or needle roller) in the bearing with cage usually arranged evenly between the two races as a rolling motion, its shape, size and number of direct influence on bearing load capacity and service performance. Cages except for rolling elements can be separated evenly, but also guiding the rolling elements rotate and improved internal lubrication of bearings.
