Usually, the shaft is supported in the radial and axial taking two bearing, the SKF bearing side are called fixed end bearing, it can bear radial and axial load from two, relative axial displacement between the fixed shaft and bearing box function. The other side is called the free end, only bear radial load, axial movable relative to.
1, bearing selection phase, need to consider many factors (for example: load, hardness, operation environment ), tapered roller bearing design will first make SKF bearing reaches its maximum life values.
2, the correct storage, SKF bearings should be best kept in their original packaging before installation. Need to stay in a clean, free of moisture, relatively constant temperature environment. Tapered roller bearings should be kept away from water and dust, corrosive chemicals. Mechanical properties of shaking and vibration will always be possible damage to the bearing, it should avoid the vibration in the processing and storage process.
General bearing should be the level of preservation, SKF bearing long time vertical some heavier after placement, and deformation due to its own weight!
Also, coated with grease ( or seal ) bearings need to be especially careful, because the grease after the density change after long time storage. When the SKF bearing is used for the first time, there will be a certain degree of rotation noise. So, this kind of tapered roller bearings use time should be to control the FIFO principle!
3, clean, it is very important for rolling bearing. Plane of rotation SKF bearing ring is very smooth, very sensitive to pollutants caused damage. Particulate impurities will be excessive rolling rolling element and partial pressure in the tapered roller bearings, will eventually lead to fatigue of permanent materials.
4, fully installed equipment, SKF bearings appropriate tools should be used cautiously installation and disassembly ( can be disassembled series video reference bearing ). Should select the right tools! Industry experts estimate, premature failure of tapered roller bearings, 16% were caused by incorrect installation. General installation, the general would take appropriate bearing mounting device.
