Bearing grease selected direct relationship with the stable operation of the device, in order to better play the best condition of the bearing, the experts suggest that we have chosen bearing grease must b e considered from the following aspects:

1, anti-rust properties

The use of the grease in the bearing must have a rust-proof effect, a rust inhibitor is preferably water-insoluble. The grease should have good adhesion, and can form a layer of film on the steel surface.

2, the mechanical stability

Grease in the mechanical processing will become soft, resulting in leakage. In normal operation, grease the bearing housing flung. If the mechanical stability of the grease is insufficient, the operation of the process, make grease soap structure to produce mechanical disintegration, cause the grease to be destroyed, and thus loss of lubrication.thin section bearing

3, seal

Oil seal from external contamination barrier is necessary for the protection of bearings and lubricants, bearings during operation, regardless of the debris or moisture can not penetra te the bearings, to avoid causing its destruction.

Proper installation and maintenance is to play an important factor in the longest bearing life. Meanwhile, we must pay attention to the cleanliness of the bearing, bearing the correctness of the choice and selection of proper installation and maintenance tools. Further, the bearings must be protected against contaminants and moisture contamination and to ensure correct installation and lubrication. Therefore, the bearing design with the column, the condition of the oil seal, lubricant type and lubrication cycle, and even specialized care and plays the same important role.

4, mixed oils and fats

Should never be incompatible greases, if two incompatible greases, usually its consistency becomes soft, easy to drain grease may cause damage to the bearing. If you do not know what kind of grease the bearings of the original use, you must completely remove the old grease of the bearing inner and oute r, in order to add new grease.

5, grease classification

Distinction according to the temperature and working conditions: the grease can be classified according to their allowable working temperature, the consistency of the grease and lubricating ability is influenced by the working temperature, the bearings must be operated at a temperature To select the correct consistency at the same temperature and good lubricating effect of the grease. Grease is manufactured for different operating temperature range, can be broadly divided into low temperature, the temperature used and high-temperature grease. The same time, there is a class of fats known as the crush resistance or resistance to crushing and adding molybdenum disulfide, at the same time, in add additives to enhance the strength of the lubricant film.slewing bearing

6 to select the grease important factor

If the wrong ch oice grease all bearings prevention measures futile select a grease base oil viscosity at the operating temperature is able to provide sufficient lubrication effect is very important, the viscosity is mainly influenced by the temperature, as the temperature rise and fall, when the temperature drops is increased. Therefore, you must know the base oil viscosity at operating temperature. Machinery manufacturers usually specify the use of some kind of fat, however, most of the standard grease for a very wide range.
