Why Bearings Need Lubrication?

Release time: 2016-05-10

Theoretically, a well-oiled, in an ideal working conditions, bearing life should be to never, of course, is simply not possible, but if correctly lubricated bearings, the bearings will reach the longest working life. Rolling bearing lubrication to reduce internal friction and wear, to prevent the burning stick, and its lubricating effect as follows:

1, to reduce friction and wear. Constitute the bearing rings, rolling contact with each other and the retainer part of the formation of a layer of film, even in the case of heavy load, but also to prevent the metal contact, reducing friction, wear and tear.

2, extending fatigue life. Fatigue life of rolling bearings, rolling contact surfaces in the rotation good lubrication, the extension; the other hand, the end of the oil viscosity lubricant film thickness is not good, is shortened.

3, the discharge of frictional heat, cool. Cycle oil to the oil law to discharge the heat generated by friction or heat coming from the external cooling. Prevent bearing overheating and prevent its aging oil.

4, other. Inside the bearing to prevent foreign invasion, or to prevent rust, corrosion effects.
