Because the bearings of the jaw crusher need to adapt to high-speed and high-strength working pressure, regular replacement of the bearings is inevitable, so how to choose the appropriate model for the jaw crusher bearing?
1. For the choice of jaw crusher bearings, it is necessary to meet the requirements of external load, and try to give full play to the load capacity of the bearing itself. Therefore, the bearings must comply with the following requirements: radial load is greater than axial load, fulcrum span is large, shaft deformation is large, etc., and it is best to use self-aligning bearings.
2. In the choice of accuracy, the tolerance of the inner and outer rings of the bearing should not exceed 0.05mm. If the accuracy of the bearing is higher, the ordinary grade bearing can be changed to the C3 grade bearing.
3. The clearance of rolling bearings is pided into radial clearance and axial clearance, which respectively represent the amount of movement of one ring from one limit position to another in the radial and axial directions when one ring is fixed. If you want to increase the service life of the bearing, you can adjust its working clearance value to a negative value slightly smaller than zero.
