29 sets of bearings (radial bearing) radial runout of assembled bearing outer beat ring outer radial
The outer ring at different angular positions relative to the inner ring, the outer diameter surface and maximum and minimum radial distance between the fixed points of difference. The angle position of the point or in the nearby on both sides of the rolling body shall be with the inner, outer ring raceway of the inner ring rib (or the back taper roller bearing inner surface contact parts), which is in the relative position of the normal bearing.
30 (radial clearance of bearing, No external loading direction, at different angles, a ring relative to the other, moving to the opposite extreme position of the radial distance of the arithmetic mean value from a radial eccentric limit position. This average includes mutual displacement of http://www.tanchin.hk/hk-bearing-5-151.html ring or washer at different angular positions and the rolling body have different angular positions relative to the displacement of ring or washer.
The 31 theory (radial clearance radial contact ball bearing) theoretical radial internal clearance
The outer ring raceway contact diameter minus the inner ring raceway contact diameter minus two times the diameter of the rolling body.
32 axial clearance (bearing, can bear axial load in the two direction non to the tight state) axial internal clearance
No external load, a ring or a washer with respect to another ring or washer is moved toward the axial distance limit position instead of the arithmetic mean from one axial position limit. This average includes mutual displacement of ring or washer at different angular positions and the rolling body in different angular positions relative to the displacement of the ring or washer.
