Teach you how to choose the NSK bearing lubrication way - bearing knowledge

Select the NSK bearing lubrication in one of two ways: oil lubrication and grease lubrication. Each have advantages and disadvantages of the mode of the two kinds of lubrication. Grease lubrication general scroll NSK bearings with grease lubrication. Its advantage mainly include: design is very simple grease sealing function can be a lot of low maintenance cost, long service life under normal working and environmental conditions, oil 'lifetime lubrication' can be realized. If under the condition of high load ( Speed, temperature and load) , it is necessary to replace the grease on a regular basis. In order to replace the grease, we must set up supply and exclude the pipeline of the grease and collecting used grease collector. For the occasion of the grease to be replaced short cycle, necessary to inject grease pump and valve should be set up. NSK bearing lubrication when near the mechanical parts have been used for oil lubrication or need to rely on lubricating oil cooling, NSK bearing lubrication should be adopted. In the NSK bearings under heavy load or high speed, or with external heat incoming, there may be cooling requirements. Trace the lubrication method is used, such as oil drip lubrication, oil mist lubrication oil and lubrication, NSK bearings ensures stirring oil loss and friction are small. When using do air carrier, could directly and make the air helps to seal oil. NSK bearing high rotational speed and need good cooling jiao fruit, a large number of lubricating oil can be directly spray to all of the contact surface. 1. NSK import bearing lubrication and keeping clean is very important when we inspection on imported bearings before, should first clean the surface of NSK bearings, NSK bearings and careful check of the oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace the bad oil seal will cause damage, NSK bearings make cloud caused by abnormal equipment downtime. 2. We also check import NSK bearing lubricant lubrication is very important, not only for NSK bearings, also for all the import bearings. Note, however, Japan NSK bearings shoulds not be too much grease. And then replace the NSK bearing lubricant. NSK bearings used engine oil lubrication after xie used engine oil, if possible, shall be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. NSK bearings with grease lubrication in replacing grease, Joe used in addition to the device should be avoided with cotton material come into contact with any part of the NSK bearings. Because these residues fiber may wedged in between the scroll and damage, especially the application of small bearing more need to pay attention to this problem. 3. It is important to note covering exposed NSK NSK bearings imported bearing inspection, don't let bearing exposure to pollutants or moisture environment. If the job is interrupted, should with oil film, paper or similar material by machine. If don't have to remove and may perform inspection of cleaning without masking of bearing, to coating with brush with petroleum solvent ( ) Cleaning and dry with a lint-free cloth or with compressed air to blow dry, Be careful not to let the bearing component starting rotation) 。 With a little mirror, and the probe used in the similar to the dentist to check the bearing of the orbit plane, retainer and beads. Do not clean the encrypted block or dust bearing; You just wipe the outer surface. If the bearing is need to replace damaged situation. During regular maintenance downtime time replacement bearings than the array bearing damage of selected into a sudden stop loss is much more economical.
