The best condition in order to better play to bearing, SKF bearing grease choice is good or not directly related to the stable operation of the equipment.
The selection of the bearing grease must consider from the following aspects: 1.
Rust resistance corrosion inhibitor is best can not dissolve in water.
Grease should have good adhesion, use within the bearing grease must have antirust effect.
And a layer of oil film can be formed in the steel surface.
Mechanical stability to leak.
During normal operation, oil will become soft in machining.
Grease can by the bearing to the bearings.
If the mechanical stability of the oil is insufficient, operation process, can make the structure of the soap grease mechanical disruption of oil was damage, and loss of lubrication.
Oil seal SKF bearing operation process, the oil seal is necessary maintenance of bearing and lubricant from outside the barrier of pollution.
Regardless of debris or moisture can penetrate bearings, in case of causing damage to it.
Have a bearing on the correct device goes is the longest service life of the important factors.
At the same time, must pay attention to the purity of the bearing, bearing of correctness and choose the proper installation and maintenance tools.
In addition, the bearings must prevent contamination by pollutants and moisture, and ensure the right device and lubrication.
Therefore, the design of the bearing arrangement, the condition of the oil seal, type of lubricants and lubrication cycle, and special care are the same and important role.
Mixed oil if two incompatible oil mixture, never can't compatible to the oil to mix.
Usually will soften its consistency, might end up bearing damage caused by oil easy to loss.
If you don't know which bearing the original use of grease, is required to completely remove bearing inside and outside of the old oil, can add new grease.
The classification of the grease lubrication grease consistency and ability is operating under a certain temperature under the influence of working temperature of SKF bearing must choose under the same temperature has the correct consistency and good lubrication effect of oils and fats.
Oil is made of different working temperature range can be roughly divided into low, medium temperature and high temperature with grease.
At the same time, mainly according to the temperature and the working conditions to distinguish: oil can be classified according to its allowable working temperature.
There is a certain type of oils and fats known as resistance to squeeze or extrusion and add molybdenum disulfide, at the same time, among them with additives to enhance the strength of the lubricating oil film.
Choose grease the important factor in choosing a grease, if the wrong choice grease all measures to prevent bearing is useless.
Base oil viscosity in the working temperature is it is important to be able to provide adequate lubrication effect of viscosity is mainly affected by temperature, the temperature rise and fall, when the temperature drop is increased.
Therefore, it is necessary to know the working temperature of base oil viscosity.
Machinery manufacturers are usually specified use some grease, however most of the standard grease applicable range is very wide.
Need before checking surface cleaning machine, and then remove the SKF bearing the perimeter of the parts.
Oil seal is very fragile parts, the need to carefully remove, not excessive force, and then carefully check oil seal and its surrounding parts, if the present adverse symptoms, be sure to replace the bad oil seal will cause the damage of the bearing and severe equipment downtime.
Check the lubricant, with little lubricant in friction between two fingers, and if the presence of pollutants, can feel that, or in the back with a thin layer of lubricant, then seal of inspection.
Replacement of lubricants, oil lubricated bearings after xie used engine oil, oil impregnated with fresh and let the machine in low speed rotation for a few minutes.
As far as possible make the oil collecting residual pollutants, then spilled oil in addition to these, the oil before use it's best to filter it.
Grease lubrication bearing in replacing grease used by Joe in addition to the editor should avoid to any part of the bearing with a cotton by Angle, because these residues fiber may wedged in between the scroll and damage, especially the application of small bearings need more attention.
Covering exposed bearings, check the SKF bearing, don't let the bearing exposure to pollutants or moisture environment.
If the job is interrupted, should with oil film, paper or similar material by machine.
If don't have to remove and may perform inspection of cleaning without masking of bearing, to clean with brush with petroleum solvent coating, then dry with a lint-free cloth or with compressed air to blow dry,
Be careful not to let the bearing component starting rotation)
Do not clean the encrypted block or dust bearing;
You just wipe the outer surface.
If the bearing is need to replace damaged situation.
In regular maintenance downtime period than the array bearing replacement SKF bearing damage selected into a sudden shutdown loss much more economical.
