Because of the tapered roller bearing thrust roller for tapered roller, on the structure of the bus and gasket because rolling roll are in bearing HuiJiao bus way of online at some point axis, and rolling the surface can be pure rolling, forming limit speed higher than cylindrical roller thrust bearing.

Thrust taper roller bearings can withstand one-way axial load.

Thrust tapered roller bearing type code 90000 type.

Because thrust tapered roller bearing capacity of less, GeChang already production models for more than the standard size shape, size and shape of the standard series, variety production less, so there is no such bearing the overall size on the national standard.

Thrust Angle contact ball bearing contact Angle for 60 ° general common thrust Angle contact ball bearing general for two-way thrust Angle contact ball bearing, mainly used for precision machine tool spindle, general and double row cylindrical roller bearing used together, it can be subject to bi-directional load, with high precision, good rigidity, low temperature, high speed, installation convenience etc.

Contact fatigue damage is bearing the main form of damages to the normal. The rolling bearing operation, roller bearing inner and outer in the groove between rolling and its contact part of the bears a periodical alternating load, much every minutes up to hundreds of thousands of times, in periodic alternating stress under the action of repeated, contact surface appear fatigue spalling. The rolling bearing began to appear spalling will cause bearing vibration and noise of the temperature increase sharply, the bearing final damage, the damage form called contact fatigue damage. Therefore, the requirement with steel rolling bearing should have high contact fatigue strength.

The rolling bearing normal work, in addition to occur outside the rolling friction, accompanied by sliding friction. The main parts occurred sliding friction is: rolling body and groove of the interface between, rolling body and maintains a pocket between hole of the interface, maintains a collar and raised edge and roller surface between lead and guide between collar raised edge. The rolling bearing of the existence of sliding friction inevitably make bearing parts produce wear. If bearing steel wear resistance is poor, rolling bearing will wear for early loss or because of the rotation accuracy and precision decline of bearing vibration increase, the life is reduced. So, ask bearing steel should be high wear resistance.

 
Double row circular cone roller bearings structure is various, the maximum amount of 35000 type, have a double groove outer ring and two inner circle, two inner circle a circle between isolation, change the circle of the thickness can be adjusted clearance. This type of bearings in bear radial load at the same time it can be subject to bi-directional load, can be in bearing axial clearance range limit axis and the shell of the axial displacement.
