Clean the surface of the machine before inspection, and then remove the parts around the Cuscinetto INA. The oil seal is a very fragile part, so it needs to be disassembled carefully.
Do not apply excessive force, and then carefully check the oil seal and its surrounding parts. If there are Ina Self-Aligning Ball Bearings bad symptoms, be sure to replace it. The bad oil seal will cause damage to the self-aligning ball bearing and strict equipment shutdown.
Rub a little lubricant between your fingers. If there are pollutants, you can feel it, or apply a layer of lubricant on the back of your hand, and then seal it for light inspection.
After draining the old oil, if possible, refill fresh oil into the oil lubricated INA Bearing and let the machine rotate at low speed for a few Ina Self-Aligning Ball Bearings minutes. Make the engine oil collect residual pollutants as much as possible, and then drain the engine oil. The engine oil is filtered before use.
For grease lubricated bearings, the arbor used when replacing grease should avoid connecting the angle of cotton to any part of the bearing, because these residual fibers may wedge between the rolling parts and cause damage, especially for the application of small self-aligning ball bearings.
Under some special service Ina Self-Aligning Ball Bearings conditions, adding a small amount of solid lubricant to the grease, such as adding 3 ~ 5% bisolfuro di molibdeno 1, can reduce wear and improve compression and heat resistance.
Viscosity is an important Ina Self-Aligning Ball Bearings characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of oil film formed between friction surfaces.
The viscosity of lubricating oil at working temperature is generally 12-15cst. The higher the speed, the lower the viscosity should be selected, and the heavier the load, the higher the viscosity should be selected.
Oil lubrication methods include:
un. Oil bath lubrication
Oil bath lubrication is a common lubrication method, which is suitable for low and medium speed lubrication.
Part of the self-aligning ball bearing is immersed in the groove, and the Ina Self-Aligning Ball Bearings lubricating oil is brought up by the rotating parts and then flows back to the oil groove. The oil surface should be slightly lower than the center of the low rolling element.
Oil dripping lubrication is suitable for INA Bearing parts requiring quantitative supply of lubricating oil. The amount of oil dripping is Ina Self-Aligning Ball Bearings generally one drop every 3-8 seconds. Excessive amount of oil will increase the bearing temperature.
c. Circulating oil lubrication
The filtered oil is delivered to the components by the oil pump, and the filtered lubricating oil is used after being filtered and cooled. Since the circulating oil can take away a certain amount of heat and reduce the temperature, this Ina Self-Aligning Ball Bearings method is suitable for bearing parts with high speed.
D. spray lubrication
The dry compressed air is mixed with the lubricating oil through the sprayer to form an oil mist. In the jet, the airflow can effectively cool down and prevent impurities from invading. This method is suitable for the lubrication of high-speed and high-temperature parts.
e. Jet lubrication
Use the oil pump to inject the high-pressure oil through the nozzle, and the injected oil flows into the oil Ina Self-Aligning Ball Bearings groove through the other end. When the bearing rotates at a high speed, the rolling element and cage also form an air flow around at a fairly high rotation speed.
When checking the self-aligning ball bearing, never expose the bearing to pollutants or moisture. If the work is interrupted, the machine shall be Ina Self-Aligning Ball Bearings covered with oil paper, plastic sheet or similar materials.
If the INA Bearing without cover can be cleaned without disassembly and inspection, it shall be cleaned with a brush coated with white spirit, and then wiped dry with a piece of lint free cloth or blown dry with compressed air (be careful not to start the rotation of the bearing assembly).
Do not clean the sealed cover or dust-proof bearing; Just wipe the outer surface. If ina bearing is damaged, replace it immediately. During the regular shutdown and maintenance period, the loss of sudden shutdown caused by replacing the damage of self-aligning ball bearing is much more economical.
