Basic method for inspection and maintenance of IKO mill bearings

In general, if the IKO bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidents that are prematurely damaged and are not resistant to use. This early damage, as opposed to fatigue life, limits the quality of what is known as a fault or accident. Many of them are caused by inadvertent installation, use, and lubrication, and foreign objects intruding from the outside are insufficiently studied for the thermal effects of the shaft and the outer casing. Regarding the damage state of the rolling mill bearing, for example, the jamming of the ferrule rib of the roller bearing, as a cause, the lubricant is insufficient, unsuitable, the defect of the oil supply structure, the foreign matter intrusion, the bearing installation error, the shaft deflection If the song is too big, there will be coincidences of these reasons.
Therefore, it is difficult to know the true cause of the damage by only investigating the bearing damage of the rolling mill. However, if you know the IKO bearing's use of machinery, the conditions of use, the structure around the bearing, and understand the situation before and after the accident, combined with the damage state of IKO bearings and several reasons, it can prevent similar accidents from happening again.
    The precautions for the use of IKO bearings are as follows:
    Keep rolling mill bearings and their turnaround clean
    Even small dust that is invisible to the eyes can have a bad effect on the rolling mill bearings. Therefore, keep the area clean so that the dust does not intrude into the bearing.
    Use with care
    In the use of the mill bearing strong impact, it will produce scars and indentations, which is the cause of the accident. In severe cases, cracks and breaks occur, so care must be taken.
    Use the right mill operating tools
    Avoid replacing with existing bearing tools and use the right tools. We often emphasize the importance of tools because too many customers use the wrong tools in their installations to cause damage to the rolling mill bearings.
    Pay attention to the corrosion of rolling mill bearings
When operating the rolling mill bearings, the sweat on the hands can cause rust. Be careful to use a clean hand, it is best to wear gloves as much as possible.

FAG universal joint bearing periodic inspection method

    Regular inspections of FAG bearings are important to maintaining the best condition of the universal joint bearings and can also reveal problems. Matters and related knowledge about the use of FAG bearings.
    First of all, we want to emphasize that it is important to keep the FAG bearings lubricated and clean.
Therefore, before we inspect the universal joint bearing, we should clean the surface of the FAG imported bearing and then remove the parts around the bearing. It should be noted that the oil seal is a very fragile part, so extra care should be taken during inspection and disassembly. Do not apply excessive force to avoid damage to the parts. Then carefully check the oil seal of the FAG bearing and its surrounding parts. If it has been shown to be a bad symptom, be sure to replace it. A bad oil seal will cause damage to the bearing, causing the FAG bearing to be abnormal and causing the machine to stop.
    Second, we also check the lubricant of the universal joint bearing.
Lubrication is very important, not only for FAG bearings, but also for all imported bearings. However, please note that it is not advisable to add too much grease to the bearings.
    The inspection method for FAG bearing lubricant is:
    Apply a little bit of lubricant to the two fingers. If there is any contaminant, feel it. Or apply a thin layer of lubricant on the back of the hand and check the seal.
    Then replace the lubricant of the universal joint bearing.
    FAG bearings lubricated with oil should be refilled with fresh oil and allowed to rotate at low speed for a few minutes if the old oil is drained. As much as possible, allow the oil to collect residual contaminants and then vent the oil. Note: It is best to filter the oil before use.
For grease-lubricated FAG bearings, when replacing grease, the cutter used should avoid any part of the FAG bearing with a cotton joint. Since these residual fibers may be wedged between the rolling elements and cause damage, especially the application of small bearings requires attention to this problem.
    Finally, it is important to note that the exposed FAG bearings are covered.
    When inspecting FAG bearings, never expose the bearings to contaminants or moisture. If the work is interrupted, the machine should be covered with a piece of oil-paper plastic or similar material.
    If the unshielded bearing is cleaned without performing disassembly and may be inspected, it should be cleaned with a white spirit with a brush for application, then dried with a lint-free cloth or blown dry with compressed air. (Be careful not to start the universal joint bearing assembly to rotate).
