Properly installed precision FAG bearing
For mounting precision FAG bearings products,, the installation should pay attention to some things up, if the words are not installed well, no longer bearing life. So if you want to install a FAG bearings, you should understand the method of mounting bearings, which ensures the FAG bearing damage during the installation process.　Let me introduce the following bearing precision integrated calibration method:
1, measurement of shaft and FAG bearing bore size to determine the fitting accuracy of the bearing to meet requirements are as follows,　
(1) take the inner ring and shaft fits, interference 0~+4 μ m (light, high-precision time-0);
(2) outer ring and the housing bore clearance fit, gap 0~+6 μ m (but the free end of FAG bearings with angular contact ball bearings, can also increase the gap);
(3) in surface of shaft and bore roundness 2 μ m　
(4) ring in the FAG bearings face parallelism 2 μ m　
(5) the shaft-side face of outer face beat in 2 μ m
(6) the FAG bearing block hole of pulsation of the abutments on axis 4 μ m　
(7) the axis of spindle Cap inner end face runout 4 μ m,
Rust prevention methods
Rust-proof methods for surface treatment of:
1) surface cleaning: cleaning must be rust-proof nature and prevailing conditions of surface, select the appropriate method. By common solvent cleaning, chemical cleaning and mechanical cleaning law.
2) surface is dry cleaning available filter clean dry compressed air dryer, or 120~170℃ dryer for drying, can also be used to clean dry gauze.
Coated with antirust oil
1) immersion method: soak some small bearings used in antirust oil, so its surface to attach a layer of anti-rust oil. Oil-film thickness can be controlled through the rust to reach temperature or viscosity of the grease.
2) brush coating method used for soaking or spraying does not apply for outdoor equipment or special shape products for building, accumulation of brush, while being careful to not give rise also to guard against missing coating.
3) spray some large oil-immersion method could not be applied coating of rust, generally use about 0.7Mpa pressure of filtered compressed air in air cleaning spray. Spray application of solvent-diluting antirust oil or a thin layer of rust preventive oil, but you must use a full range of fire prevention and protection measures.
