1. Thrust tapered roller bearing structure, performance characteristics:
As the thrust tapered roller bearings in the rolling element for the tapered roller, the structure of the rolling bus and the washer of the raceway bus meet at the bearing axis of a point, so the rolling surface can form a pure rolling, the limit speed Thrust cylindrical roller bearings.
In this case,
    Thrust tapered roller bearings can withstand unidirectional axial loads.
    Thrust tapered bearing housing type code-named 90000 type.
    As the thrust tapered roller bearing the production of small, the factory has produced more non-standard size of the standard size, while the standard size of the series, less variety of production, which is not such a bearing size of the introduction of national standards.
    
    2. Thrust angular contact ball bearing structure, performance characteristics:
Thrust angular contact ball bearing contact angle is generally 60 ° Commonly used thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly for precision machine tool spindle, usually with double row cylindrical roller bearings used in conjunction with, can withstand the bidirectional shaft To the load, with high precision, good rigidity, low temperature rise, high speed, easy assembly and disassembly.

    3. Double row tapered roller bearing structure, performance characteristics:
Double row tapered roller bearing structure is numerous, the largest amount is 35000 type, there is a double raceway outer ring and two inner rings, between two inner rings with a circle, change the thickness of the spacer can adjust the clearance.rod end bearing This type of bearing in the radial load can withstand the same time, two-way axial load in the axial clearance of the bearing within the axial and axial displacement of the shell.
