SKF bearing sales: the long ball bearing rust is there any danger

Shows that there is a tight one, early locomotive vehicle axle box device adopts the sliding bearing, the early years of the nineteenth century began to try rolling bearing axle box device, has been gradually replaced by sliding bearing axle box device. After we for bearing the corresponding protective measures, can obviously feel bearing wear greatly reduced, of course, we must not only pay attention to the protection timber mill bearing part, the inside of the lumber mill other vulnerable parts also need to pay attention to regular maintenance. Also need to pay attention to the special situation, some bearing fault only on tire idling is to listen to not to come out of, the car must be landed on the ground, let the bearing under pressure, can make accurate judgment. Type for the separable bearings, inner ring and outer ring can be installed separately, thus simplify the installation process, especially when the inside and outside the circle must be especially interference fit. Dyed point distribution, demanding ° - in the center of the bearing - every square centimeter in ° Angle Points so far, shoulds not be too little or too much; Otherwise, need crapping, after shaving with a white cloth dipped in alcohol clean tile face and neck, repeat the above research method, make the bearing shell dyed point scraping the thinner, the more more more, until it meets the requirements. Cylindrical roller bearings and needle roller bearings are as follows: the difference between a cylindrical roller bearing is tapered roller roller; Needle roller bearing is needle roller roller; Cylindrical roller bearing structure is relatively larger needle bearing; Cylindrical roller besides can bear radial force also can withstand the axial force, and needle roller bearings can bear radial force; Single row cylindrical roller bearing points more than double row and column, applied to different environments and situations; Cylindrical roller bearing relative to the needle roller bearing working speed is higher; Cylindrical roller bearing, is all with high quality of bearing steel and special steel; And thin needle roller bearing is chosen steel plate stamping. Choose whether or not is still bearing failure analysis must be considered appropriate, & amp; emsp; & emsp; Spherical roller bearings, outer ring has Shared the spherical raceway, there are two inner ring raceway. Note the number method/steps: axis of a dusty, circulating oil lubrication oil pump in the conversion of the filter oil transfer to the bearing parts, through the bearing lubricating oil filter cooling after use. Bearing outer ring brush tuomoji sauvy SD release agent; , reinstall and after trial, ship again put into operation, after no abnormal situation. Seal eccentric ( Touching the adjacent components and friction) ； , bearing hole diameter is too large, the actual match is too loose, Bearing temperature is too high - Outer ring skid) ； 。 Rolling bearings: single-row radial ball bearing ( Radial bearing, deep groove ball bearing) Features: mainly bear radial load, large shaft rigidity requirements applicable places: on the gearbox and the spindle type said: type double row centripetal ball bearings ( Self-aligning ball bearing) Features: mainly bear radial load, double row ball, outer ring raceway is spherical shape, with automatic self-aligning properties, can automatically compensate coaxiality error due to flexure and shell deformation applicable occasions: bearing seat holes can't keep strict alignment of parts. Example: K, I personally think in terms of brush street, bigger and more soft soft son is more important, but good bearing can actually keep your speed to be more durable.
