Flat housing, in most cases, States: with the appropriate clearance. Depending on the purpose, but also in the General Assembly, bearing, ahead of NSK bearings, internal stress, negative bearing clearance, this method is called using the preload.
(1) in the right direction and decided to shaft in the axial direction of the radial position, inhibiting beating axis.
(2) increasing bearing rigidity. Machine tool spindle bearings, cycling and small agency plane bearing gear differential.
(3) in order to prevent different sound vibrations and resonance in axial direction. Small motor bearing.
(4) inhibition of rolling rotational sliding, sliding and rotating the revolutionary slide. Spin Center of thrust bearing, thrust ball bearing.
(5), ring, keep scrolling in the correct location. Thrust ball bearings, spherical roller thrust bearings, and the horizontal axis.
Plane of the use of oil lubrication bearing after purging the old engine oil, if possible, should be poured into the fresh engine oil and make the machine at low speed spin for a few minutes. Residual oil as much as possible to collect pollutants and diarrhea in addition to these oils. Note: engine oil before use, it is best to filter.
Use grease-lubricated bearings when replacing the grease, used by Joe you should avoid contact with cotton in addition to any part of the NSK bearings. Fiber because these residues may be wedged in between the rolling and cause damage, especially small bearing application should pay attention to this issue.
When checking flat housing, don′t let the bearing is exposed to contaminants or moisture environment. If the work is interrupted, the paper should be plastic or similar material covering machine.
