Used in the INA Bearings grease with rust, rust inhibitor is preferably insoluble in water. Grease should have good adhesion, and a layer of film can be formed in the steel surface, grease become soft machining, resulting in leakage. Normal operation, the grease from the Bearings flung Bearings. If the mechanical stability of the grease is not enough, the operation of the process, makes the structure of the grease of the soap cause mechanical disintegration, caused by grease is destroyed, loss of lubrication, if the wrong choice grease all Bearings prevention measures are futile, select a kinds of oils, base oil viscosity at operating temperature is able to provide adequate lubrication is very important, the viscosity affected by temperature, it decreases as the temperature rises, it rose when the temperature dropped. Therefore, we must know the base oil viscosity at operating temperature. Machinery manufacturers usually specify the use of certain oils and fats, however, most of the standard grease for a very wide range.
In the process of INA Bearings, the grease is critical. If deterioration of grease, not only to achieve its proper role away will damage the Bearings.
① oil flow observation
Take two measuring cups, one of Sheng to be checked lubricants, and other empty on the table will be filled with lubricating oil measuring cup held high to leave the desktop 30-40 cm and tilt, so that the lubricating oil to slowly flow to the empty cup observe the flow, the quality of a good lube oil flow should be slender, uniform, continuous, if there is oil flow unsteadiness, sometimes with large shed, said lubricating oil has gone.
② hand twist
Twist the lubricant between the thumb and index finger repeatedly grinding, better lubricants hand felt lubrication, less wear debris and friction-free, if they feel the sense of a larger friction of the sand and the like between the fingers, indicates that the lubricant within the impurities can not be reused, should be replaced with new lubricants.
③ illumination method
On a clear day with a screwdriver lubricant pulled up a 45 degree angle with the horizontal plane. Control sunlight, observed droplets circumstances, in light, you can clearly see the lubricant wear debris as well, can continue to effect if too much debris, replace grease.
(4) droplets traces of France
Take a clean white filter paper, drip a few drops on filter paper, until the lubricant leakage, if the surface has a black powder, touch resistance astringent, then the lubricant inside the impurity has a lot of good oil powder, hand feels dry and smooth, and yellow traces.
   Regular Bearings temperature measurement by means of a thermometer, such as digital thermometers, can be accurately measured INA Bearings temperature according to the given unit of ℃ or Fahrenheit. The importance of Bearings, which means that when it is damaged, can cause equipment downtime, so these Bearings should preferably be the installation of temperature probes. Under normal circumstances, INA Bearings in just lubrication or re-lubrication after there will be a natural rise in temperature and lasts one to two days.
    Typically, the Bearings operating temperature above 150 ° is called high-temperature Bearings, Bearings steel using the temperature exceeds 150 °, and its hardness will be a sharp decline in the size of unstable, so that the Bearings does not work properly. INA Bearings operating temperature at 150 ° to 350 ° conditions, if the rings and rolling bodies still use ordinary carbon chromium Bearings steel, the Bearings parts special tempering process, the general should be higher than tempering temperature of 50 °. Bearings steel tempered in accordance with the above requirements, the normal operating temperature. However, tempering the hardness decreased, decreased Bearings life.
