SKF bearing installation after the test process

A, cautious according to different applications and the erection and dismantling of SKF bearing size and type, select the appropriate installation method ( Mechanical or hydraulic) And tools. Here are a few basic principles of SKF bearing installation: 1. Don't impose on rolling element installed power, this could easily lead to the rolling element and contact area of local overload, which can lead to premature failure of SKF bearing. 2. Do not use any hard tool ( For example, a hammer, screwdriver, etc. ) Direct knock on SKF bearing surface, which can lead to SKF bearing ring fracture or fracture. Second, the clean clean of SKF bearing is very important. SKF bearing ring rotation surface and the surface roughness of the rolling element is usually a 1/10 microns, such a smooth surface is sensitive to damage caused by pollutants. Lubrication layer between the rotation surface usually is 0. 2 ~ 1 microns, is greater than the lubricant type size particles of impurities are influenced by the excessive rolling rolling element and local stress in spherical roller bearing steel, eventually lead to permanent material fatigue. In addition to this, the external environment of dust particle size can be up to 10 microns, will also be pair of roller bearing damage. Therefore, clean dust-free environment for storage and installation of SKF bearing is very important. Three, process detection using thermal device can monitoring the working temperature of SKF bearing, and implement e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. With high temperature often said bearing is in abnormal situation. High temperature is also harmful to SKF bearing lubricant. Sometimes SKF bearing overheating can be classified to the bearing lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower SKF bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, the load is too large, cylindrical roller bearing damage, clearance, high friction and oil seal, etc.
