NSK tapered roller bearing grease in the use of maintenance - bearing the importance of knowledge

Removed in order to distinguish the NSK tapered roller bearing can be able to use, check in the bearing after washing clean. Check the raceway surface, rolling surface, cooperate with the state, adhere to the wear condition, the increase of the bearing clearance and has nothing to do with dimension precision landing damage, abnormal. Non separation small ball bearing, the extent of support to inner ring with one hand, rotate the outer ring can confirm fluently. Bearing maintenance: bearing cleaning: removing NSK tapered roller bearing under repair, the appearance of the first recorded bearing, confirm the residual stock of smooth agent, sampling inspection with the smooth agent, after washing bearing. Common use gasoline, kerosene as a cleaning agent. Is bearing industry, usage of that type of grease maximum bearing in high speed wire-rod mill, accounts for about 70% points with the amount of fat. Because that kind of grease used fiber soft, white light to filter of lithium do thickener, use of mineral oil for essential oil, very light is difficult to know the foot outside the low-grade bearings reduce the requirement of vibration value. Another benefit is no bad good pumping, whether mechanical fatliquoring, is still the manual besmear butter, tough is concise. And, the lower the price of the grease, NSK tapered roller bearing can greatly reduce the cost. However, due to the use of the mineral oil, make the type of grease is rust and antirust function on the outside of some physical and chemical target to play close button. Such as bearing life can reach 200 hours, linear guide to common problems. Starting and running torque is - 20 ℃ test when there is no problem. The use of grease temperature is commonly - 20 ~ 120 ℃, when was above 150 ℃ high temperature use, will bring about the ultimate oil evaporation too fast, abort the phenomenon such as severe, greatly shorten the bearing using life. 1. Bearing oil bath smooth oil bath is bearing in the ordinary way of smooth smooth, suitable for low and medium speed bearing is smooth. NSK tapered roller bearing will be partial immersion in the slot, smooth and bring up the oil by the rotation of the bearing parts, then flow back to the oil level of oil tank should be slightly lower than the lowest in the middle of the roller. 2. Bearing drip drip smooth smooth suitable for the need to ration the smooth NSK tapered roller bearing parts, oil drop of oil every 3 - individually A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased. 3. Bearing the circulating oil slick with oil pump will be filtered oil walks to the bearing parts, NSK tapered roller bearing by smooth oil filter cooling after use. Because circulating oil can take away heat, must make bearing cooling, therefore method suitable for high speed bearing parts. 4. Bearing spray smooth with dry shrinkage by air sprayer and smooth oil mixed oil mist, radial bearings, can effectively make the bearing cooling airflow and can avoid intrusion. This method is suitable for high speed and low temperature bearing parts is smooth. 5. Radiation smooth and low pressure in the oil pump oil bearing NSK tapered roller bearings, the nozzle into into the bearing of the bearing at the other end into the oil in the tank. When bearing at high speed, rolling body and maintain frame to match the rotation of the high speed air cause air flow around, it is hard to smooth the oil to the bearings in individual smooth way, then must smooth oil spray with low radiation to bearing, the status of the nozzle should be placed in the middle of the inner ring and maintain frame between.
