 SKF bearing tightness test pressure is great, especially for non-rod chamber pressure test, in the absence of tooling to withstand rodless chamber test pressure by the piston effect in a lot of pressure in the piston rod, if only by the fuel tank mouth connection to bear is definitely not. Therefore, it is usually this type of pressure test after the tank is carefully assembled, before entering the assembly machine commissioning phase. 

 When the fuel tank of the machine of the rack to withstand the enormous pressure, if the fuel tank assembly of good can be. The fuel tank pressure test in the assembly was very easy to not only save a separate trial after the pressure in the fuel tank assembly tooling, but also save the hours will shorten the production cycle, the production effect is very useful. If the operator is not careful inspection and careful work, then there will be the results worth the wait. 

 Therefore, before the assembly of SKF bearings should carefully verify the dimensional accuracy of the relevant parts of the sealing parts of the seal groove of the dimensional accuracy of ultra-poor or seal the surface roughness does not meet the requirements leaving the seal failure. Particular the inspection of the sealing lip, not defective seals put into the product. In addition, SKF bearings, seal material, hardness, and other indicators to check control and product certification and storehouse. 
 If the sample Cheng darker colors or thickens, it may be that the oil has begun to carbonation, the old grease should be completely replaced. If possible, use fresh oil on the oil flushing. Replacement of oil, should ensure that the new replacement oil, the same old models and added to meet the requirements of the oil level.

 Oil-bath lubrication system, if the oil temperature below 60 ° C (140 ° F), and the lubricating oil is not contaminated and replaced once a year lubricants can. If the oil temperature in the 60-100 ℃ (140-210 ° F), year to replace the four lubricants. If the oil temperature in the 100-120 ° C (210-250 ° F) per month need to replace a lubricant. If the temperature is above 120 ° C (250 ° F), the weekly needs to be replaced once a lubricant. 
 Proper installation and maintenance of the FAG Spherical roller bearings the normal operation of important factors, we must pay attention to maintain cleanliness of the bearing. Bearing the need to prevent pollution by contaminants and moisture, must have the correct installation and lubrication. In addition, the bearing with the column design, and oil seal, the lubricant in the form of maintenance and replacement cycle and expertise also play an important role, must be concerned. 
 Analysis of cause anomalies in the lubricating oil is good or bad FAG Bearings 
 FAG bearing grease rheology: 
 When the grease is not external force like a solid to maintain a certain shape, that is not automatically lost when at rest.

 By high shear stress (shear speed a lot), the grease flows like a Newtonian fluid, the viscosity can maintain a constant, rather than change with the change of the shear rate. 
 (3) when subject to weak external force, resulting in elastic deformation; removal of external forces, but also restored to its original position and shape, showing a solid elastic properties. 
 When the applied forces are large enough, grease the deformation and flow, and thus no longer able to automatically return to its original position and shape, the starting torque of grease on the mechanical moving parts than liquid lubricants.
