The correct installation maintenance is play INA bearing the longest service life of important factor. At the same time, must pay attention to the purity of the bearing, bearing the correctness of the choice and choose the proper installation and maintenance tools. In addition, sliding bearing must protect from pollutants and moisture of the pollution, and to guarantee the right be installed and lubrication. So with the design of the column, bearing the condition, the oil lubricant type and lubrication cycle, and special maintenance are the same and plays an important role.

4, mix oil

Never put can't compatible oil mix, if two incompatible oil mix, usually the consistency will become soft, finally may be due to oil is easy to lose and cause the damage of the sliding bearing. If you don't know the original INA bearing use is which kind of grease, it must first thoroughly clean the inside and outside of the old bearing grease, can add new grease.
Usually there are various of lubricant basic requirements:

(1) have enough of lubrication, which can reduce the friction bearings and control the bearing of the harmful wear process, friction resistance to small, anti-wear ability.

(2) prevent rusting of the bearings, itself is not lead to sliding bearing component parts (such as copper, rubber seal maintains a, etc.) of the corrosion, deterioration or deformation.

(3) can in the provision of working temperature within the scope of the upper and lower specification limits, always keep the necessary lubrication performance, stable chemical composition, viscosity change is not big.

(4) in the provisions of the rotating speed within the range of the upper and lower specification limits, can build up enough thick oil film; Itself clean, do not contain impurities, defoaming is good.

(5) in the requirements of the work within the time limit or inventory period, physical and chemical properties stable enough, does not affect the quality of the use of lower.

(6) maintenance, maintenance to simple, accessory device as little as possible.

(7) in meet the above technical requirements, under the premise of economic tries to save.

2. The additional requirements for lubricant

(1) a good cooling effect.

(2) to the surface of the lubrication have very strong adhesion, leak, drippy or even less likely to jilt; The water of separation.

(3) mixed in with a little impurity (water classification) should not affect its performance.

(4) sealing function, can prevent water or dirt into the bearings.

(5) is not easy to transfer can reduce the noise and vibration.

(6) can carry out concentrated lubrication.

3. The special requirements of lubricant
In the special conditions, and it puts forward the lubricant must be special requirements:

(1) the long life of demand the service life of lubricant especially long.

(2) low friction torque requirements of the requirements of lubricant
frictional resistance is very low.

(3) high temperature resistant demand more than 250 ℃ high temperature of ability.

(4) the requirements of low temperature resistance requirements ability-63 ℃ under low temperature.

(5) the requirements of high vacuum resistance requirements in the high vacuum conditions, non-volatile, is not lost, not bad, especially in weightlessness high vacuum conditions.

(6) harmless sex requirement
Mainly based on the temperature and working conditions distinguish: oil can allow them according to their working temperature to classification, oil and lubrication ability is the consistency is the influence of temperature, at a temperature of sliding bearings have to operate in the same temperature choice has the right consistency and good lubrication effect of grease. Oil is different working temperature range to make, can be roughly divided into with low temperature, temperature and high temperature with the grease of use. At the same time, there is a certain type of fat called resistance to squeeze or resistance to squeeze and add mos2, at the same time, in which add have additives to strengthen the intensity of the oil film.

If the wrong choice, all of the bearing grease prevention measures in vain, choose a grease, its base oil viscosity in the working temperature is can provide enough lubrication effect is very important, the influence of the temperature of mainly affected by the viscosity, it along with increasing temperature and down, when the temperature drop is it rises. Therefore, you must know the working temperature, oil viscosity. Machinery manufacturer usually specified use some kind of oil, but most of the standard applicable range of grease is very wide
