4 Requirements for the selection of bearing seats
JB/T 2563--91
4.1 The bearing is allowed to bear a small axial load through the shoulder. When the shoulder diameter is not less than the outer diameter of the bearing shoulder, the axial load allowed is not more than 30% of the maximum radial load. 4.2 The load direction of the bearing seat should be within 35° to the left and right of the bearing centerline perpendicular to the separation surface, as shown in Figure 2. The shaded part in the figure is the range of radial load allowed. Figure 2
4.3 The surface of the journal that matches the bearing seat should be hardened. 4.4 The size of the journal fillet should be selected according to GB6403.4. 5 Technical conditions
The technical conditions of the split four-stud oblique sliding bearing seat should comply with the provisions of JB/T2564. 395
