Adjusting and Measurement of Miniature bearing---TIC BEARINGS

During operation, the bearing requires correct relubrication to perfect its performance. Miniature bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, we must choose a lubrication method suitable for the use conditions and purpose. If only lubrication is considered, the lubricity of oil lubrication is dominant. But grease lubrication has the advantage of simplifying the structure around the bearing.

The accuracy level of the bearing is gradually increased from 0 level, which is sufficient for general purpose 0 level, but when used in the conditions or occasions shown in Table 1, accuracy level 5 or higher is required.

Dimensional accuracy (items related to shaft and housing installation)

1. Allowable deviation of inner diameter, outer diameter, width and assembly width

2. The allowable deviation of the inner and outer round diameters of the roller group

3. Allowable limit value of chamfer size

4. Allowable variation of width

Rotation accuracy (items related to the beating of rotating body)

1. Allowable radial runout and axial runout of inner ring and outer ring

2. Allowable lateral runout of the inner ring

3. Allowable variation of the inclination of the outer diameter surface

4. Allowable variation of the thickness of the thrust bearing raceway
