FAG bearing fault handling method

Each type of FAG bearing envisions a common eradication process. Regarding the smaller bearings, there is a driver who can assist in bearing removal. If the operation is not done, it can protect the bearing, shaft or shell, and requires expensive training. As a result, heavy-duty light industrial bearings have been earmarked for a small amount of profit. When absorbed into a new or reformed bearing, it is not packed from the package until the preparation device is in use. This is especially the case in light industry use, often the task environment is inferior, heavy loads, dirt and purification are rare areas.

Heat lamps or other heating facilities can be used. Even the hands or large batches of chemical gloves that are wet or uncovered can cause the engraving to be in a small sea area, which can cause bearing fatigue. Regarding the installation with tight cooperation, or pressing, or has been locked in the center of the first axis, there is no machine to remove the bearing puller, the inner ring of the bearing can be heated to increase the relocation. If it was once a torch, it would change the function of the bearing steel and the bearing must be discarded.

The service life of any FAG bearing is at a large level originating from the protection and maintenance of its absorption. FAG bearings are stocked with special anti-erosion coatings, but most of the bearings are not built with anti-corrosion materials. Bearing performance can lead to noble downtime, facility protection and problems. This includes bearing storage, cleaning, cleaning, testing and installation. The idea of ​​using anti-collision bearings for everything.

Bearings are not subject to high humidity or sudden and violent measurements, which can lead to condensation. Without the type of bearing, the bearing must be removed especially inadvertently. There is no indirect storage on the lime floor, where it is able to condense water collection and bearings.

In order to operate reliably and with minimal protection profits, accurate solutions must be followed. Bearings being solved and stored must be inadvertently ensured that they do not rust or erode.

The FAG bearing was built and reformed with cover insulation. It is generally covering the cover paper or the rest of the package and is being transported in a suitcase or wooden case. We push bamboo paper or Xu, if not, we are racing plastic sheet of roller and tapered roller bearing cup. The tea tray or bearing FAG bearing on the store shelves is a major component of the once-minor light industrial facility.

Several techniques for identifying FAG bearing quality and bearing maintenance

1. Is the outer packaging clear: Under normal circumstances, the factory brand has its own presupposed presupposition for the external packaging, and the factory that has passed the production conditions is manufactured and manufactured, because the packaging is from the line to the line. The color blocks are very clear and unambiguous. Whether the steel printing is clear: brand letters, labels, etc. will be printed on the FAG bearing body. The font is very small, but most of the products produced by the factory use the stamping technology, and the typeface is applied before the heat treatment, because the font is small, but the depth is very clear. The imitation of the fonts of the fake products is not only vague, because the printing technology is not delicate, the fonts float on the outside, and can be wiped off by hand even a little.

2. Is there any noise: hold the FAG bearing inner sleeve in the left hand, and turn the outer right to make it rotate to hear if there is any noise. Because most of the counterfeit products are lagging behind, the absolute hand-operated operation is difficult to avoid impurities such as sand in the production process, which is hidden in the bearing body, so the noise will be emitted at the moment of rotation. This is the biggest difference between a factory brand that strictly enforces production standards and operates with machines.

Whether there is turbid oil on the outside: this should be appreciated when purchasing FAG bearings. Because the anti-rust technology in China until now is not especially home, it is easy to leave a thick oil trace when applying anti-rust treatment to the bearing body. It is sticky and thick in the grip, and the bearing on the overseas original is almost I can't see the remnants of anti-rust oil, but it is especially meticulous to say that the FAG bearing smells like a smell, it must be under the anti-rust oil, just can't see it. Whether the chamfer is average: the chamfer of the bearing, that is, the seam of the horizontal and vertical faces, the imitation of the impersonated bearing is unsatisfactory in the corners of these corners due to the limitation of production technology.

In order to maintain the original performance of the FAG bearing in a good condition for as long as possible, it is necessary to maintain, repair, and prevent accidents, ensure the reliability of operation, and improve productivity and economy. Maintenance is best carried out on a regular basis in accordance with the operating standards for the mechanical operating conditions. The content includes monitoring of operating conditions, replenishment or replacement of lubricants, and periodic disassembly inspections. As a maintenance item during operation, there are bearing rotation sound, vibration, temperature, lubricant state, and the like.

FAG bearing cleaning: When disassembling the FAG bearing for inspection, first record the appearance of the bearing, confirm the residual amount of lubricant, and after sampling the lubricant for inspection, wash the bearing. As a cleaning agent, gasoline and kerosene are commonly used. The FAG bearings removed are cleaned and cleaned separately. They are placed in the container and placed on the bottom of the metal mesh so that the FAG bearings do not directly touch the dirt of the container. In rough cleaning, if the bearing is rotated with dirt, it will damage the rolling surface of the bearing and should be noted. In the rough cleaning oil, use a brush to remove the grease and the adhesive. After it is almost clean, it is transferred to the fine wash. Fine washing is to carefully clean the bearing while rotating it in the cleaning oil. In addition, the cleaning oil should always be kept clean.

Inspection and judgment of FAG bearings: In order to judge whether the removed bearings can be used, the bearings should be cleaned and inspected. Check the raceway surface, the rolling surface, the state of the mating surface, the wear of the cage, the increase in the FAG bearing clearance, and the damage and abnormality that are irrelevant in dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring horizontally and rotate the outer ring to check if it is smooth. Separate bearings such as tapered roller bearings can be inspected separately for the rolling surfaces of the rolling elements and the outer ring. Large bearings cannot be rotated by hand. Pay attention to the appearance of rolling elements, raceways, cages, and ribs. The higher the importance of bearings, the more careful inspection is required.
