2.Application:

Tapered roller bearings are widely used in automotive, rolling mill, mining, metallurgical, plastic machinery, etc

3.The method of bearing installation:

(1) cleaning bearings and related components;

(2) Check the connected components of size and finishing machining;

(3) Installation 

(4) inspection of the bearings after installed;

(5) the supply of lubricant. 

4.Working Principle :

Tapered roller bearings mainly bear with radial, the axial union load. Bearing outer ring rolling bearing capacity depends on the way Angle, the greater the carrying capacity of the larger Angle. This type of bearings is bearing separation, according to the bearing of the roller column number into a single, double row and four row circular cone roller bearings. The single row circular cone roller bearing clearance to users in the installation to adjust; Double row and four row circular cone roller bearings clearance has set up a file in the products based on user requirements given, don't need to adjust by the user. 

5.Service life :

Automobile bearing life is one year etc.

6.Note:

To make the bearing keep high performance and long-term use in good condition,you must carry on the inspection and maintenance of the bearing.
