Tapered roller bearings 32948 for electrical equipment

       Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the angle is related to the calculation factore: the larger the value of e, the larger the contact angle. A single row tapered roller bearing is typically adjusted against a second tapered roller bearing.

       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 .
