Pebble crushing machine bearing lubricant selection techniques

A rust-resistant for use in bearing grease must have rust, rust inhibitor preferably insoluble in water. Grease should have good adhesion, and can form a film on the steel surface.

2, the mechanical stability of the grease in the mechanical processing will become soft, resulting in leaks. During normal operation, the bearing grease flung bearing. If the mechanical stability of oil is not enough, during operation, make the structure of the soap grease mechanical disintegration, causing oil to be destroyed, and thus loss of lubrication.

3, seal oil seal is required to protect bearings and lubricants from external contamination barrier, bearings during operation, regardless of debris or moisture can not penetrate the bearings, to avoid causing its destruction. Proper installation and maintenance is to play an important factor bearing the longest life. Meanwhile, we must pay attention to the cleanliness of the bearing, bearing selection is correct and choose the appropriate installation and maintenance tools. Further, the bearings must be protected against contamination and moisture contamination and to ensure that there is proper installation and lubrication.

4, mixing oils should never be incompatible greases, if two incompatible greases, usually its consistency becomes soft, it may eventually cause the loss due to bearing grease easily damaged. If you do not know the original use of the bearing grease which one, you must completely remove the old grease bearing inner and outer, before adding new grease.


5, the classification of oils according to the temperature and working conditions distinguished: oils according to their allowable working temperature to the classification, the consistency of grease and lubricating ability is affected by the operating temperature, operating at a temperature of the bearing must be chosen in the same temperatures have the right consistency and good lubrication oil. Fat in a different temperature range manufactured can be broadly classified into low-temperature, medium temperature and high temperature grease used. Meanwhile, there is a class of fats known resistance to crushing or resistance to crushing and adding molybdenum disulfide, at the same time, in which the lubricant with additives to enhance the strength of the film.

6, an important factor in selection grease grease if the wrong choice of bearing all the preventive measures is futile, select a fat, its base oil viscosity at operating temperature to be able to provide adequate lubrication is very important, mainly by the viscosity
