The smooth effect of SKF bearings can be briefly stated as follows:
a. An oil film is formed between the two rolling surfaces or the sliding surface touched by each other to separate the two surfaces; the collision and wear of the touch surface are reduced.
b. When the oil is smooth, especially when the circulating oil is smooth, the oil mist is smooth and the fuel injection is smooth; the smooth oil can take away most of the conflict heat inside the bearing; it has a useful heat dissipation effect.
c. When the grease is smooth, it can avoid foreign matter such as dust from entering the bearing;
d. Smoothing agents have the effect of avoiding metal corrosion.
e. The fatigue life of the extended bearing.
As we all know, the surface of the work will always have the minute gauge on the SKF bearing end face or the appropriate part of the shaft; even if the SKF bearing parts are processed with the highest production skill of the world, investigate the way the reading changes with the preload load. The pre-tightening method has its suffocating aspects; for example, the conflicting torque of SKF imported bearings is increased, the temperature rise is improved, the life is shortened, etc.; therefore, all must be considered; the level is small and the errors are small; the roller SKF bearing and the measuring clearance The shaft or SKF bearing housing needs to be rotated in different directions for several weeks; to ensure that the SKF bearing at the end of the ball is properly touched with the leading edge on the inner ring.
Continued wear and tear will lead to gradual damage to SKF bearing parts. Cooperative voids increase and work surface tracing changes; and end leads to SKF bearing dimensional accuracy loss and other associated problems. Wear can affect shape changes. Can affect smoothing or contaminate Reaching a certain level and forming a smooth function is completely lost; thus making it even impossible to work properly.
