Structure and performance characteristics of five types of bearings

As the rolling element in the thrust tapered roller bearing is tapered roller, the rolling generatrix and the raceway generatrix of the gasket converge at a certain 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 can withstand unidirectional axial load.

The type code of thrust tapered roller bearing is 90000.

Due to the small production volume of thrust tapered roller bearings, most of the models that have been produced by various factories are non-standard overall dimensions, while the series of standard overall dimensions have less varieties, so there is no national standard for the overall dimensions of such bearings.

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, which is mainly used for precision machine tool spindles. It is generally used together with double row cylindrical roller bearings, and can withstand two-way axial loads. It has the advantages of high precision, good rigidity, low temperature rise, high speed, and {TodayHot} easy assembly and disassembly.

Structure and Performance Characteristics of Double row Tapered Roller Bearings

Double row tapered roller bearings have various structures, a large number of which are 35000 types. They have 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 type of bearing can bear both radial load and bidirectional axial load, and can limit the axial displacement of the shaft and housing within the axial clearance range of the bearing.

Structural characteristics of tapered roller bearings.

The type code of tapered roller bearing is 30000, and the tapered roller bearing is a separate type bearing. In general, especially within the dimension range of GB/T307.1-94 Rolling Bearings Radial Bearing Tolerances, the tapered roller bearing outer ring and inner component can be used interchangeably. The angle of the outer ring and the diameter of the outer raceway have been standardized as the same as the overall dimensions. It is not allowed to change during design and manufacturing. So that the outer ring and inner component of tapered roller bearing can be interchanged within the range.

Tapered roller bearings are mainly used to bear the combined radial and axial loads mainly composed of radial loads. 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 in one direction of shaft or housing.

Characteristics of deep groove ball bearing?

In structure, each ring of deep groove ball bearing has a continuous groove {HotTag} raceway whose cross section is about one-third of the equatorial circumference of the ball.

Deep groove ball bearing is mainly used to bear radial load, but also can bear certain axial load.

When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the axial load alternating 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 type of bearing selected by users.
