The radial internal clearance of the spherical plain bearing is the value before the outer ring is split. Refer to Table 4, Table 5 and Table 6. The radial internal clearance of the inch series is shown in the dimension table. Our company also sells joint bearings other than the above clearance, please consult Qingdao Ruijing Electromechanical Equipment Co., Ltd. Radial internal clearance of oil-filled spherical plain bearings SB, SBA Radial internal clearance of oil-filled spherical plain bearings GE Radial internal clearance of non-oil-filled spherical plain bearings GEEC. The recommended fits for joint bearings are shown in Table 7 and Table 8. ■Bearing selection table 7 　Recommended matching conditions for oil-filled spherical plain bearings. Normal working conditions include h6, j6, m6, n6, H7, J7, M7, and N7 tolerance zone class shaft bearing housing when non-directional load is applied. Remarks when the bearing housing is light alloy Recommend N7. Table 8 'Remarks on the tolerance range of the recommended mating shaft of the non-oil-filled joint bearing: h6, j6, H7, J7, K7 tolerance range of the bearing seat' K7 is recommended when the bearing seat is a light alloy.
