We all know that self-aligning ball bearings must have sufficient lubrication in order to ensure the effective and reliable operation of the bearing. After lubrication, the use effect of the bearing will be improved, and it is also conducive to maintenance and performance. But there are still many people who don’t know what are the benefits of lubrication for the use of self-aligning ball bearings? After summarizing, it is known that self-aligning ball bearings will have many benefits after being lubricated. It seems that lubrication is of great help to the use of bearings.

Benefits of self-aligning ball bearing lubrication:

1. Prevent or reduce the direct metal contact between the rolling elements, raceways and cages in the bearing to reduce friction and wear;

2. An oil film is formed on the friction surface. When the pressure oil film is formed, the contact bearing area of the parts can be increased, so it can reduce the contact stress and prolong the fatigue life of rolling contact;

3. Lubricant has anti-rust and anti-corrosion effects

4. Oil lubrication also has the effect of dissipating heat and taking away the wear particles or intrusive pollutants generated during the operation of the bearing;

5. Grease lubrication can increase the sealing performance and prevent the intrusion of external pollutants;

6. It has a certain effect of reducing vibration and noise.

Don’t think that lubrication will bring benefits to the self-aligning ball, not necessarily. In many cases, there are some invalid lubrication for self-aligning ball bearings not only does not help, but will bring some disadvantages. Therefore, when we lubricate the self-aligning ball bearing, we must deal with it according to the corresponding actual situation, and it can only operate normally after confirmation.
