In addition to the excellent quality, self-aligning ball bearings are also very precise parts. If they are not used properly during use, they will not only fail to achieve the expected performance results, but also easily damage the FAG bearings. Everyone must have paid attention to lubrication.
In addition to lubrication, there are other aspects that need to be paid attention to during the use of self-aligning ball bearings. Eric Bearing Limited will discuss with you.
Matters needing attention in the use of self-aligning ball bearings
1. When using and installing, you must be careful not to allow strong punching, and the motor bearing has bad phenomena.
2. Use appropriate and accurate installation tools. Try to use special tools as much as possible, and try to avoid using things like cloth and short fibers.
3. Try to keep the self-aligning ball bearing and its surrounding environment clean. FAG bearings generally use sodium-based grease. Even if the smiling dust that is invisible to the naked eye enters the self-aligning ball bearing, it will increase the self-aligning ball bearing wear, vibration and noise.
4. To prevent the corrosion of FAG bearings, when taking the self-aligning ball bearings directly by hand, the sweat on the hands should be fully washed away, and then coated with high-quality mineral oil before the operation, especially in the rainy season and summer, pay special attention to anti-rust.
Under certain special operating conditions, self-aligning ball bearings can achieve a longer life than traditional calculations, especially under light loads. The mechanism and influencing factors of self-aligning ball bearing box labyrinth seal analysis. These special operating conditions are that when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricating oil film and limit the surface damage that may be caused by contaminants.

Several methods of FAG cylindrical roller bearing failure treatment
According to the formation mechanism of the FAG bearing working surface grinding metamorphic layer, the main factors affecting the grinding metamorphic layer are the role of grinding heat and grinding force. Let's analyze the reasons for the failure of cylindrical roller bearings.
The main purpose of preload: The main purpose of preload and representative examples can give some examples to prove and understand:
(1) While correctly determining the positions of the radial direction and the axial direction of the shaft, the shaft runout is suppressed.
(2) Improve the rigidity of FAG bearings. Bearings for the main shaft of the machine tool and bearings for the pinion gears of the differential mechanism for cycling.
(3) Prevent axial vibration and abnormal noise caused by resonance. Bearings for small motors.
For cylindrical roller bearings that are subjected to combined loads, due to the increase in the number of load-bearing rolling elements, the friction resistance increases, the amount of fever increases, the lubrication and cooling conditions become worse, and the force acting on the cage also increases, so , Must be adjusted according to the FAG bearing type and the size of the load angle, the bearing's limit speed multiplied by a reduction .
If the selected limit speed of the cylindrical roller bearing cannot meet the application requirements, some improvement techniques can be adopted to make progress to reach a more satisfactory request. Such as increasing the tolerance of bearing tolerance; properly increasing the clearance; using special materials and improving the structure of the stick frame; changing the lubrication method, such as adopting oil and gas, oil mist and jet lubrication; improving the cooling conditions.
Treatment steps when the temperature of cylindrical roller bearings rises
In the process of using FAG bearings, the phenomenon of temperature rise is easy to occur. When the temperature of the cylindrical roller bearing rises, first determine whether it has been misused. If it does rise, it should be treated as follows:
1. Check the cooling water pressure, water flow and piping system are normal. If the water pressure is low, it may be that the filter is clogged. If it cannot be processed in time, it can be stopped for processing. When it is confirmed that it can work, it can be put into use again.
2. The oil pressure of the governor should be checked. If the oil pressure is low, the cooling water hydraulic valve may be closed.
3. Check whether the FAG bearing has abnormal sound, and detect whether the swing of the cylindrical roller bearing is abnormal.
4. Take an oil sample and observe whether the oil color has changed, and conduct a test to see if it has deteriorated. If deterioration is confirmed, it should be stopped and replaced with new oil.
5. Check whether the oil level of the oil standard is normal, if it is abnormal, check whether the oil drain valve of the oil tank is tightly closed. If it is tightly closed, oil should be refilled. If the sealant is oily, it should be shut down for treatment.
