Proper installation and maintenance is an important factor in the longest service life of INA bearings. At the same time, attention must be paid to the cleanliness of the bearings, the correctness of the choice of bearings and the selection of appropriate installation and maintenance tools. In addition, the plain bearings must be protected from contamination and moisture and ensure proper installation and lubrication. Therefore, the design of the bearing arrangement, the condition of the oil seal, the type of lubricant and the lubrication cycle, and even the special maintenance play the same and important role.
4, mixed grease
Never mix incompatible greases. If two incompatible greases are mixed, the consistency will usually be soft. In the end, the sliding bearings may be damaged due to the easy loss of grease. If you don't know which grease is used in the INA bearing, you must completely remove the old grease inside and outside the bearing before adding new grease.
There are usually the following basic requirements for lubricants:
(1) It has sufficient lubricating effect, which can reduce the friction of the bearing and inhibit the harmful wear process in the bearing. The frictional resistance is small and the anti-wear ability is large.
(2) Preventing corrosion of the bearing, which itself does not cause corrosion, deterioration or deformation of components of the sliding bearing (such as copper cages, rubber seals, etc.).
(3) It is possible to maintain the necessary lubricating performance within the range of the upper and lower limits of the specified operating temperature, and the chemical composition is stable and the viscosity does not change much.
(4) A sufficiently thick oil film can be established within the range of the upper and lower limits of the specified working speed; it is clean, free of impurities, and has good defoaming properties.
(5) Physical properties and chemical properties are stable enough during the required working period or during the inventory period, so as not to affect the quality of the use.
(6) Maintenance and maintenance are simple and the attachments are as small as possible.
(7) Under the premise of meeting the above technical requirements, economically strive to save.
