To basis without the use of the same and the bearing measured and type, the choice of the way of a suitable means (machine or hydraulic) and the machine. The smooth periodic originated in the operating environment, the similarity metric, speed, condition. Review and protection of the frequency of secondary originated in the operating environment of the general use of major and various facilities. The accurate destruction, deliberate device and assembly, remaining smooth and re-smooth, accurate form of monitoring, timely protection, initially perfect training progress thrust angular contact ball bearings use of life expectancy and facilities functions are extremely main .
Axial angular contact ball bearings are generally the main components in the pump and other facilities, class quality bearings extremely solid, but to ensure they have the use of the longest life expectancy, and still have to pay more attention. The Department has a law review will be early detection of latent are the achievements and prevention of the emergence of tools expected to stop the scene, the consumer program to be completed, progress workshop spending power and frequency. Thus, the increase in vibration and conflict can be greatly increased power-consuming, and the risk of premature entry into force.
Grease should never be incompatible mix, mix two incompatible grease, usually its consistency will become soft and may eventually cause damage to the bearing grease is easy to lose. If you do not know what kind of thrust angular contact ball bearings originally used grease, you must completely remove the bearings inside and outside the old grease before adding new grease.
Distinction based on the temperature and the working conditions: the grease can be classified according to their allowable working temperature grease consistency and lubrication is affected by the working temperature, operated at a temperature of thrust angular contact ball bearings must be selected at the same temperature under the correct consistency and good grease lubricating effect. Grease manufactured by a different working temperature range, can be broadly divided into a low temperature, the temperature used and the high-temperature grease.
Meanwhile, there is a class of fats known as extrusion resistance or resistance to extrusion and added molybdenum disulfide, with additives, in which in order to enhance the strength of the lubricating oil film.
If the wrong choice grease all bearings prevention measures futile select a grease, the base oil viscosity in the working temperature is able to provide adequate lubrication effect is very important, the viscosity is affected by temperature, it is as the temperature increased and decreased, it is increased when the temperature drop is. Therefore, it is necessary to know the base oil viscosity at operating temperature.
Machinery manufacturers usually specify the use of a fat, however, most standard grease for a very wide range of
The following is a selection grease several important factors: mechanical types; thrust angular contact ball bearing type and size; Operating Temperature; workload situation; speed range; work situation, such as vibration and spindle direction is horizontal or vertical; cooling situation; sealing effect; external environment
