FAG QJ226N2 bearing

Content Applicable Bearing Type

Fixed-end bearing: used to locate and fix the bearing axially. Select bearings that can bear radial and axial loads at the same time. In order to withstand the bidirectional axial load, it is necessary to consider the corresponding strength according to the size of the axial load during installation. Deep groove ball bearing combined angular contact ball bearing, double row angular contact ball bearing, self-aligning ball bearing, cylindrical with rib, roller bearing (NUP type, NH type), double row roller

Spherical roller bearings

Free end bearing: used to avoid the expansion and contraction of the shaft caused by temperature changes during operation, and to adjust the axial position of the bearing. It is advisable to choose a bearing that only bears radial load and the inner ring and outer ring can be separated. When using non-separable bearings, a clearance fit is generally adopted between the outer ring and the housing, so that the shaft can be extended and retracted together with the bearing for axial avoidance. Used to avoid the temperature during operation.

The expansion and contraction of the shaft caused by the change and the adjustment of the axial position of the bearing. It is advisable to select a bearing that only bears radial load and the inner ring and outer ring can be separated. When using non-separable bearings, a clearance fit is generally adopted between the outer ring and the housing, so that the shaft can be extended and retracted together with the bearing for axial avoidance. When the fixed end and the free end are not distinguished, when the bearing spacing is small and the influence of shaft expansion and contraction is not large, it will be able to two angular contact ball bearings or tapered roller bearings that can bear axial load are configured on the front or back.
