Bearing Tread back interference measurement methods are pressure lead method and measurement. First, the pressure lead method In the tile back and bearing surface were placed on the surface of the diameter of about 0.10 ~ 0.20mm lead wire measurement, the difference between the average thickness of the two lead wire pressure, that is, back tile with the gap or interference. Tile back of the lead wire thickness is less than the bonding surface of the lead wire thickness, is the amount of interference. In general, the interference of plain bearings is 0.01 ~ 0.05mm, for rolling bearings, the interference is -0.01 ~ 0.01mm. Second, the measurement method Measured with a micrometer outer diameter of the shell and the bearing bore, the former minus the latter, the difference between the two diameters is the amount of interference.
