NSK bearing import of 5 kinds of knowledge - bearing lubrication methods

Under the condition of high speed, high temperature, NSK bearings imported grease lubrication has not timely lubrication can be used. Through the circulation of lubricating oil, can take away a lot of calories. Is an important characteristic of lubricating oil viscosity, viscosity directly affect the liquidity of lubricating oil and the size of the friction surface is formed between the oil film thickness, the bearing working temperature of lubricating oil viscosity is usually 12 - 15cst。 Speed the Gao Yingxuan lower viscosity, the more load weight should choose high viscosity. Commonly used lubricating oil has high-speed machine oil, machine oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc. Oil lubrication methods include: 1. Oil drip lubrication oil drip lubrication is suitable for need to ration oil import NSK bearing parts, drip oil every 3 - general A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased. 2 circulating oil lubrication oil pump in the conversion of the filter oil transfer to the bearing parts, NSK import by bearing lubricating oil filter cooling after use. Due to the circulating oil can take a certain quantity of heat, cooling the bearing, therefore method is suitable for high speed bearing parts. 3. Oil bath lubrication oil bath lubrication is the most common method of lubrication, NSK import bearing lubrication is suitable for low and medium speed, bearing part of immersion in the slot, the bearing parts of lubricating oil by rotating, and then flow back to the oil level of oil tank should be slightly lower than the lowest at the center of the roller. 4. Spray lubrication with oil pump to pass through the nozzle in high pressure oil bearing, NSK bearing import into the bearing at the other end into the oil in the tank. When bearing at high speed, rolling element and cage with high rotate speed makes the surrounding air, the air in general it is difficult to be sent to the bearing lubricating oil lubrication method, then must use the method of high-pressure jet spray the lubricating oil to the bearings, the position of the nozzle should be placed between inner ring and retainer center. 5. Spray lubrication with dry compressed air after the sprayer and lubricating oil mixed form oil mist, spray bearing, can effectively make the bearing cooling airflow and can prevent the intrusion. This method is suitable for high speed NSK import bearing, high temperature parts lubrication.
