The correct use of FAG bearings

  • FAG bearing dismantling should use the appropriate puller to pull out the assembly hole in the bearing housing, in the case of size, shape, precision is not appropriate, the bearing will be affected by it.
  • For example, if the commonly used parts bearing seat size accuracy and shape accuracy is not good will affect the bearing outer ring deformation, resulting in bearing bore roundness deterioration; if the shoulder accuracy is not good, it will occur bearing outer ring sleeve, roller column tilt, intensify the concentration of load, so that its life decreases, more serious will cause attachment frame fracture, sintering.

Refined selection of FAG bearings

  • If the FAG bearings inner ring spindle gear precision is not good, such as size, roundness, cylindricity, ripple degree, roughness, position degree and other aspects of accuracy, also will obviously incur the whole set of spindle vibration value increased. FAG Bearings in the assembly before the severe fine matching, so the user in the use of the former, loose bearing parts without new measurement matching, is not able to exchange the use.
  • Concerning the cleaning of spinning spindle Set of FAG bearings and spindle feet.Because of the compact structure of the spindle foot, spindle foot cavity has many other parts.
  • Therefore, the assembly before the use of spindle foot parts pre-cleaning, assembly assembly in the future, and then the assembly spindle foot including bearings for fine cleaning process is more reasonable process approach.


The bearing in the assembly should not be bump and impact, bump and impact easily formed between the collision of bearing parts, resulting in bearing failure. Bearing seat roll edge to pay attention to control the edge of the angle, strength and other factors, to prevent the edge of the unreasonable formation of bearing parts of the deformation of the effectiveness. On has exceeded the anti-rust period or storage time longer bearing, rolling bearing commission life have considerable potential to develop rust or due to anti-rust oil dry and roller sticky dead condition.
