Check is required prior to clean the surface of the machine, and then remove the bearing surrounding parts. The seal is very fragile parts, need to be careful disassembly, do not use excessive force, and then carefully check the oil seal and the surrounding parts replaced, be sure to have shown adverse symptoms, poor seal will lead to bearing damage and serious equipment downtime.bearing factory in china
Check the lubricant, the stained little bit of lubricant in the friction between two fingers, if the contaminant, feel it, or coated with a thin layer of lubricant on the back of your hand, then seal-ray examination.
Replace the lubricant, oil-lubricated bearings in addition to the old oil spilled, and then poured into the fresh oil and let the machine a few minutes at low speed rotation. As much as possible so that the oil collected the remnant contaminants, then spilled oil, oil is best to use filtered.
(1) The provisions of the measuring instrument
Used when the measuring instrument must be calibrated, and having to adapt the precision of the measured bearing and enlargement ratio.
(2) allow the measurement error
C an, in principle, allow the measurement error in the tolerance of 10% or less.
(3) the probe radius and the pressure of the measurement table
In order to reduce the measurement error must be within a possible range, strive to reduce the pressure of the measurement table, - the measuring force and increase the radius of curvature of the measuring head.
In the measurement of the inner and outer diameters of the bearing, the measuring force and the radius of curvature of the probe can be used with reference to the selection.
(4) measuring the temperature conditionsminiature bearing
Measuring the ambient temperature requirement is 20 ℃, including bearings, gauge blocks, standard parts, and the temperature of the measuring instruments must be the same as above them on the same piece of metal plate can be the fastest way to achieve the necessary temperature balance, otherwise take severa l hours or even days to achieve this balance.
In order to get the correct measurement results, foreign manpower measurement mechanization to avoid contact with these objects or oven mitts to operate.
