Precision bearings installed correctly imported rust method

One of imports properly installed precision bearings 
      Installation of bearing products for imports for one-off installation up and pay attention to something, and if not installed, then the import will not long bearing life. So, we need the import the import bearings installed, you should know to install their own methods of imported bearings, so as to ensure that imported bearing damage during installation. Following me to introduce comprehensive check the accuracy of imports bearing installation method:
   
      1, measuring shaft and bearing bore size of imports, in order to determine with precision bearings imports to meet the requirements are as follows,
    (1) The inner ring and the shaft to fit, shrink range 0 ~ +4 μm (in light load, high-precision time 0);
 
    (2) the outer ring and bearing holes to take the import clearance fit, clearance volume of 0 ~ +6 μm (in the free end of the imported bearings angular contact ball bearings imports, but also increase the gap);

    (3) axis and the seat surface hole roundness error in the 2μm

    (4) nsk bearing the seal ring used in parallel across the 2μm
 
    (5) axis within the shoulder in the face of external face of the beating 2μm
 
    (6) shoulder block imports of bearing hole on the axis of the beating in the 4μm

    (7) spindle axis of the front cover facing the inner end of the beating in the 4μm,

      Second, rust-proof method

      Objects to be rust surface pretreatment methods:

    1) Surface cleaning: cleaning the surface rust should be according to the nature and conditions of the time, select the appropriate method. Commonly used with solvent cleaning, chemical treatment and mechanical cleaning methods clean.
  
    2) Wash the surface dry and dry compressed air drying can be filtered, or with 120 ~ 170 ℃ in the dryer for drying, can also be clean, dry gauze.

    Anti-rust oil coating method

    1) immersion method: some small bearings used in the antirust oil soak in, let adhesion on the surface layer of rust-proof method of oil. Film thickness by controlling the temperature of anti-rust oil or viscosity to achieve.
 
    2) Brush law does not apply for soaking or spraying the outside of construction equipment or special shape products, it is necessary to pay attention when brushing does not produce accumulation, but also pay attention to prevent the leakage of coating.

    3) spraying large rust coating material can not be used immersion oil, usually with about 0.7Mpa pressure compressed air filters clean places spray in the air. Spray application of solvent-dilution type rust preventive oil or thin antirust oil, but must be equipped with fire prevention and labor protection.
