1. size benchmark requirement
NSK bearings using a comparative measurement measurement of dimensional tolerance, provides comparative size benchmarks for measuring amount of blocks or parts as, which gauge block must comply with the provisions of the standard JB/T1078 of the gauge blocks and standard components must comply with the provisions of the factory authorities.
2. the provisions of the measuring instrument
Used for measuring instrument must be calibrated and commensurate with the measured NSK bearings precision and zoom ratio.
3. measurement provisions of the regional
For NSK bearing inner diameter and outer diameter measurements, domestic provisions leaving rings in the South end for a maximum chamfer coordinates of the area covered by the measure, and abroad provides for twice times before leaving the ends of the rings surface chamfer coordinates of the area covered by the measure.
4. permitted measurement errors
Could, in principle, allow for the measurement error in the tolerance of 10%.
5. the probe RADIUS and measurement of pressure
In order to reduce measurement error, must as far as possible, seeks to reduce the measurement of pressure-measuring force and increase the probe radius of curvature.
When measuring the NSK bearing inner diameter and outer diameter, radius of curvature can be used to measure force and probe reference selection
