Bearing: Imported Rolling how to meet the requirements of the role and

    Kunshan bearings: the role of such bearing with stationary ring and the rotating bearing ring and the mounting part, respectively, the stationary part (usually the bearing) and a rotating part (usually the shaft) together with consolidation, in order to achieve the rotation transmission state loads and limited motion system position relative to the stationary system's basic tasks.
  On the shaft and bearing, the bearing requirements in the radial, axial and tangential direction in three directions fixed its position. Radial and tangential positioning through the tight fit of the bearing rings mining achieve axial positioning only in a few cases, a tight fit; generally use limit axial parts, such as end caps and rings etc. is limited to the axial position in the clearance range.
     Select match should focus on the following four points:
     (A) the taper roller bearing rings and the circumferential surface should be well supported even by force, in order to reduce distortion, and give full play to the bearing capacity.
     (2) In its mating surface of the ferrule can not slide along the tangential direction, otherwise it will damage the mating surfaces.
     (3) the free end of the shaft and the bearing must be capable of bearing adapt to changes in length of the hole, which must have to adapt to the axial position in a range of swimming ability.
     (4) must be taken so that the bearing mounting and dismounting is simple, saving time and labor costs.to strengthen technology research, improved processing techniques to improve processing quality and reduce the possibility of processing defects. If the heat treatment on the larger species inside and outside the ring, as far as possible with the minimum quenching temperature, holding time to adapt to enhance the alloying concentration, increasing the fracture strength of martensite, and in the selection of the premise of guaranteeing quality higher tempering temperature of the workpiece in order to enhance impact toughness.
 Improved processing means of monitoring and promoting quality improvement process. Such as improving the monitoring of the flow path curvature position, improve the car's overall performance after bearing assembly, improving working conditions INA bearings.
