Product Description

  1.   Tapered roller bearing 32212u  70*110*28 .


    Tapered roller bearing included cup and cone there two parts.Cup is outer ring, Cone comprise rollers,cage,inner ring.And the inner ring with the rollers and cage can be fitted separately from the outer ring.

    The tapered roller bearings are generally used to support comnined load mainly consisting of radial load. The carrying capacity of axial load depends on the contact angle of raceway of outer rings. The bigger the contact angle is, the strongerr the capacity will be .

  2. Bearing assembly rules :  

    Bearing during assembly should be assembled in accordance with the requirements below'll tell you about what bearing assembly principle:

    (1) the assembly process, to make the center line of the shaft and the bearing hole coincide. Should the tilt, installation difficulties, but will also cause indentation, journal bending, or even cause the bearing inner ring fracture.

    (2) does not allow hand hammer directly beat the bearing outer ring, the inner ring.

    (3) heating the assembly of a large amount of interference and medium-sized bearing should avoid bearing direct bearing contact with the oil temperature is much higher than the bottom, in order to avoid local overheating leaving the rolling element and the inner and outer ring raceways annealing lose their hardness .

  3. Applications for tapered roller bearings:

    1)Agriculture, 2)Light textile,3)Mining,4)Food &beverage,5)Pharmaceutical,6)Chemical processing,

    7)Printing,8)Dyeing,9)Airport,10)Air-conditioning,11)Various kinds of conveying and rolling devices.

  4. We also can offer following bearings , please check .
