Typically, the axis is based on two bearings in radial and axial support, at this point, the side is called a fixed-side combination bearings, which bear both radial and axial load, fixed relative axial displacements between shaft and housing. Call free on the other side, only take radial loads, axial can be relatively mobile, as a solution to scale axis due to the temperature change problems and installation of FAG bearings after every error.
For a fixed-side bearing, choose rolling surfaces available to the axis you want to move or to move bearing Assembly part. On the short axis, fixed and free sides had virtually no other cases, using a one-way-only fixed axial movement of the bearing.
1. combined bearings before mounting environment kept clean not beat with metal utensils, with hydraulic or hydraulic means the bearings are installed. After installation, can run to a sound, to judge the FAG bearings are properly installed.
2. combination bearing environmental considerations, there is corrosion-free material, the environment is clean, running equipment vibration, operating hours and other factors should be taken into account.
3. use lubrication maintenance is in place, FAG bearings lubrication is critical importance because lubricants have many effects:
A. grease lubrication, prevents external dust and other foreign matter entering the bearing, played a close role.
B. role of lubricant to prevent corrosion of metals.
C. two roll surfaces in contact with each other or the sliding surfaces form a thin oil film between two surfaces separated by reducing friction and wear of contact surfaces.
D. oil lubrication, especially with circulating oil lubrication, oil mist lubrication and oil lubrication, the lubricant can get bearing most of the internal friction, efficient thermal dissipation role to play.
E. extension of fatigue life of bearings.
4. bearing its own quality factor is critical, when buying make sure you on the rigidity of bearings, speed, precision, clearance, bearing parameters to understand thoroughly and avoid performance cannot be compatible with the conditions of FAG bearings the bearing itself too fast arc damage.
