The quality bearing grease selection is directly related to the stable operation of the device, in order to better play the best condition of bearings, the following are several important factors grease selection: mechanical type; bearing types and sizes; operating temperature; workload situation; speed range; work, such as vibration and the spindle is horizontal or vertical; cooling conditions; sealing effect; the external environment.
With the grease in the bearing must be rust, anti-rust agent preferably insoluble in water. Grease should have good adhesion, and can form a film on the steel surface.
Grease in the mechanical processing will become soft, resulting in leaks. Normal operation, the bearing grease flung by aligning ball bearings inside. 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.
Since lubrication of cost and ease of use, 80% of the sliding bearings lubricated bearings of the bearing grease as the "basic elements", and the bearing, bearing and seals are equally important. Rolling developed based on experience through continuous testing and research, the production of high-quality bearing grease to meet the appropriate field applications. Aligning ball bearing grease Engineering Research Center has developed strict standards and test parameters, and has become an internationally recognized benchmark bearing grease.
It is based on the application and lubrication of the bearing's extensive knowledge and experience to provide customers with self-aligning ball bearing lubrication lubrication as the core of a comprehensive service to address long-standing industrial enterprises lubrication problems, such as: improper lubricant selection , mechanical failure caused by insufficient lubrication, lubrication and lubrication cycle to determine the amount, excessive consumption of lubricant, lubrication of the environment pollution and so on. To help enterprises to improve quality and efficiency of the use of lubricant to ensure equipment operation rate and lower costs.
If the wrong choice grease is all preventive measures for self-aligning ball bearings futile, choose a fat, its base oil viscosity at operating temperature to be able to provide adequate lubrication is very important, viscosity mainly affected by temperature, it varies the temperature rise and fall, when the temperature drop is its increased. Therefore, you must know the operating temperature of the base oil viscosity. Machinery manufacturers usually specify the use of certain oils, greases, however most of the standard scope of application is very broad.
