Bearing Classification Characteristics

Bearing Classification 

1、 Structure and performance characteristics of thrust tapered roller bearing

Because the rolling body in the thrust tapered roller bearing is a tapered roller, structurally, the rolling bus and the raceway bus of the washer meet at a point on the axis line of the bearing, so the rolling surface can form pure rolling, and the limit speed is higher than that of the thrust cylindrical roller bearing.

The thrust tapered roller bearing Bearing Classification can bear unidirectional axial load.

The type code of thrust Bearing Classification  tapered roller bearing is 90000.

Due to the small production of thrust tapered roller bearings, most of the models produced by various factories are non-standard overall dimensions, while there are few varieties of series with standard overall dimensions. Therefore, at present, there is no national standard for the overall dimensions of this kind of bearings.

2、 Structure and performance characteristics of thrust angular contact ball bearing

The contact angle of thrust angular contact ball bearing is generally 60 °. The commonly used thrust angular contact ball bearing is generally a two-way thrust angular contact ball Bearing Classification bearing, which is mainly used for the spindle of precision machine tools.

It is generally used together with double row cylindrical roller bearing, and can bear two-way axial load. It Bearing Classification has the advantages of high precision, good rigidity, low temperature rise, high speed, convenient assembly and disassembly, etc.

3、 Structure and performance characteristics of double row tapered roller bearing

There are many structures of double row tapered roller bearings, a large number of which are 35000 type. Bearing Classification There is a double raceway outer ring and two inner rings. There is a spacer between the two inner rings.

The clearance can be adjusted by changing the thickness of the spacer. This kind of bearing can bear both Bearing Classification radial load and bidirectional axial load, and can limit the axial displacement of shaft and housing within the range of axial clearance of bearing.

4、 Structural features of tapered roller bearings

The type code of tapered roller bearing is 30000, and the tapered roller bearing is a separate bearing. In general, especially in GB / T307 The outer ring and inner assembly of Bearing Classification tapered roller bearing within the size range involved in 1-94 tolerances for radial bearings of rolling bearings can be used interchangeably.

The angle of the outer ring and the diameter of the outer raceway are the same as the overall dimensions and are standardized. It is not allowed to change during design and Bearing Classification manufacturing. So that the outer ring and inner components of tapered roller bearing can be interchanged all over the world.

Tapered roller bearings are mainly used to bear the combined radial and axial load dominated by radial load. Compared with angular contact ball bearing, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or shell in one direction.

5、 Characteristics of deep groove ball bearing

Structurally, each ring of deep groove ball bearing has a continuous groove raceway with a cross section of about one-third of the circumference of the equatorial circle of the ball. Deep groove ball bearing is mainly used to bear radial load and certain axial load.

When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the alternating axial load in two directions. Compared with other types of bearings with the same size, this type of bearing has small friction coefficient, high limit speed and high precision.

It is the preferred bearing type for user selection. Deep groove ball bearing has the advantages of simple structure and convenient use. It is a kind of bearing with large production batch and wide application range.
