32304 The High Quality Of Tapered Roller Bearing
The 32304 bearing is a tapered roller bearing with an inner diameter of 20 mm , an outer diameter of 52 mm, a width of 21 mm. It typically uses p0 p4 p5 p6 grade precision tolerances and open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Taper roller bearing :
Taper roller bearing belong to separation type bearing, bearing inner and outer raceway all have the cone line. This kind of bearing with roller according to the number of columns is divided into single row, variable column and four row circular cone roller bearings and so on the different structure pattern. Single row circular cone roller bearings can bear radial load and axial load in one direction. When bearing bear radial load, will produce a axial component, so when need another may withstand the reverse direction axial force bearing to be balance. Single row circular cone roller bearings under axial load ability depends on the contact Angle, namely outer raceway Angle, Angle is bigger, axial load capacity is bigger .
Taper roller bearing is the largest amount of single row circular cone roller bearings. In the car wheel hub, in recent years is also played by the small size of the double row circular cone roller bearings. Four row circular cone roller bearings used in large cold, hot rolling mill and other heavy machine.
