Precision INA bearing installed correctly rust method

A, correct installation precision of INA bearings for installation precision INA bearing products, to install a should pay attention to some things, if we get good is not installed, can make the bearing life is not long. So if you want to install good INA bearings, then you should understand the installation method of bearing, so as to ensure the INA bearing damage during the installation process. I'd like to introduce the following bearing installation precision calibration method: 1, the measurement axis and INA bearing the size of the hole, to determine with precision of the bearing, cooperate with the requirements as follows, ( 1) Inner ring and the shaft to interference fit, interference was 0 ~ + 4 microns ( At light load, high precision of 0) ; ( 2) Outer ring and bearing hole clearance fit, the interval 0 ~ + 6 microns ( But on the free end using angular contact ball bearing, INA bearing can also increase the clearance) ; ( 3) Shaft and hole surface roundness error in 2 microns ( 4) INA bearings used in space ring end face parallelism in 2 microns ( 5) Shaft shoulder end foreign face beat in 2 microns ( 6) INA bearing axis hole block shoulder to beat in the 4 microns ( 7) Spindle axis inside the front cover end face beat in 4 microns, the second, rust prevention methods are rust the surface pretreatment methods of content: 1) Surface cleaning: cleaning must be rust in accordance with the nature of the surface and the conditions, select the appropriate method. There are usually used solvent cleaning, chemical cleaning and mechanical cleaning. 2) Surface available filter after dry clean dry compressed air blow dry, or in 120 ~ 170 ℃ dryer for drying, also can use clean cloth to wipe dry. Coating anticorrosive oil method 1) Soak method: small bearing by soaking in antirust oil, make its surface adhesion on a layer of anti-rust oil. The temperature of the oil film thickness can be controlled by anti-rust oil or viscosity to achieve. 2) Brush method used for soaking or spraying outdoor construction equipment or not apply special shaped products, brush should not only pay attention to not build up, also should pay attention to prevent leakage. 3) Spray a few large rust cannot be oiled by soaking method, generally about 0. 7 mpa pressure filtering compressed air spraying where clean air. Spray method used solvent XiShiXing rust-proof oil or thin layer of anti-rust oil, but must use perfect fire protection and labor protection measures.
