NTN bearing when using error detection methods

Rolling bearing is precision components, and its use should be measured accordingly. No matter how high performance bearing use, if use undeserved, high performance will not be expected. When using the NTN bearing must pay attention to the following: 1, keep the bearing and the surrounding clean. Even the eyes can't see the little dust, also can bring bad influence to the NTN bearing. So to keep the surrounding clean the dust from invading bearings. 2, carefully use in use for bearing strong impact, will produce scar and creasing, become the cause of the accident. Severe cases, can crack, fracture, so must pay attention to. 3, use the appropriate tools to avoid operation with existing tools to replace, must use the appropriate tools. 4, to pay attention to the corrosion of the bearing operating NTN bearing, sweat will become the cause of rust. Pay attention to the operation with clean hands, it is better to try to bring gloves. 5. The provisions of the benchmark in the comparative measurement method for measuring bearing size tolerance for, dosage of rules or standard for comparison measuring the size of the benchmark, the gauge block must conform to the standard JB/T1078 'gage block' regulation, standard parts must comply with the provisions of the competent department of factory. 6. The provisions of the measuring instrument used in the measurement instrument must be calibrated, and have adapted to the NTN bearing measurement precision and magnification ratio. 7. The provisions of the measuring area for bearing inner diameter or outer diameter measurement, domestic regulations leave the ring on the southern side of one of the biggest chamfering coordinates within the area of measurement, and foreign many regulations to leave the ring twice in two end chamfering coordinates within the area of measurement. 8. Allow the measurement error in principle error of measurement may be allowed in the tolerance of less than 10%. 9. Probe radius and the pressure of the inventory in order to reduce the measurement error, must be within the scope of the possible, makes every effort to reduce inventory pressure Force is measured and the increase of gauge head radius of curvature. When measuring the inner and outer diameter of the NTN bearing, measurement and head of radius of curvature can be used in reference to choose
