(1)   False axis
A. false axis diameter and the actual work of the bearing journal is a difference of less than0.05mm, the centerline of the false axis and the work horizontal vertical error of less than0.02mm.
B. bearing assembly in the false axis, twist tight carve bolts, gap 0.02mm feeler carved face.
C. frame dial gauge and lift up and down along the vertical direction in the work radial bearings, the dial indicator reading is assumed to be S (mm), consider the tendency of the tile around the effect, the practical bearing clearance C (mm), the structure of the five-watt: C = 0.894S
In addition, the need to included in the false axis and the difference of the actual journal.
(2) lift Wafa
Lift watts measured by the gap method of calculation and measurement methods and false axis’s the same, but should be hanging out of the rotor, supported on bracket elevation move  bearing can.
(3) of lead wire method
A. wire diameter should be 30-50% larger than the measured gap.
B. 0.02mm feeler gauge to check the bearing shell carved face and bearing carved face, carved face should be no gap and good mouth.
C. Measuring two Wawa block on the middle at the wire thickness S, the actual bearing clearance C is: C = 1.1S
