Improper installation may result in injury of FAG bearings. If running under high speed conditions and higher temperatures, should pay special attention to co-operation of rotating rings must not be too loose, to prevent the emergence of the eccentric vibration, as well as fixed rings combined with no gaps, in order to prevent fires ring deformation under load and vibration.
Rotating ring of burning of interference where possible should be made smaller. As long as the practical working temperature of thermal expansion affect, as well as the maximum speed under the influence of centrifugal force, does not cause tight fit only creeping or sliding on the surface. Fixed rings depending on work load size and FAG bearing size, select minimal clearance fit or an interference fit, too loose or too tight is not conducive to precise shapes. Accurate calculation of the interference of rotating rings tie, also to precise calculation of the fixed amount of suitable tie rings. Shaft and hole of vertical degree of roundness and abutments to be in accordance with the FAG bearings the corresponding precision requirements. Cage assembly accuracy depends on a dedicated Assembly positioner guarantees, fully guaranteed FAG bearings assembled accuracy requirements.
For heavy loads, should normally be in collaboration with the light and normal loads tight. Heavy the load, which tie in with the greater the interference should be. Using pairs of FAG bearings spindle, mostly lighter load, combined with excessive interference, then its internal axial preload can be significantly larger, resulting in adverse effects ...
FAG bearings were salvaged in order to determine whether to reuse, to check its size, rotate, precision-oriented, internal clearance as well as the mating surfaces, Raceway, cage and seal ring.
