Bearing model query: how NN3018k bearing spindle design

GCr abrasion resistance and hardenability higher than GCr steel, bearing steel cutting machining, cold strain and plastic medium, poor weldability, is more sensitive on white dots to form, heat treatment has a tendency to temper brittleness. Line: don't put grease on the bolt, the normal operation of the motor and keep operating temperature, grease will be extended to uniform distribution, until the redundant grease from fat mouth eduction, thereby reducing internal pressure; 。 After sealing process, after coating also need maintenance master process not only kept the ball cage universal joint and horns, also received owner's thumb up, MM, a new structure for the liner and push a baffle between the seals, seal liner and outer surface of inner diameter for the rubber, the lip is prelubricated with waterproof grease. After grinding the bearing ring production process was basically completed, at the same time, the owner in other shipyard custom the same series of ship appeared similar problems. If you must want complement lubrication, before the installation of the bearing be necessary to remove the plastic cover on the outer ring lubrication hole, when adding grease, will slowly into the outer ring of lubricating grease hole, and rotating bearing, can make the new grease evenly distributed in the bearings. Adopt the on-site installation, commissioning equipment, general matching type bearings can be arbitrary In series, face to face or back to back) Rear matching installation, code-named UA, UO and UL. Com/x/page/SVFQ, heat removal of the operation method is the coil winding to directly to the inner ring of the rolling road to heat expansion, make the bearing easily removed. Import set-contained spherical bearing advantage free maintenance: imported from photosensitive WeiHuXing ball bearing units into suitable for sealed bearings use high quality lithium base grease, can use for a long time. Diving deep well pump, where the improvement is as follows: skeleton oil seal modified single mechanical seal, the purpose is to prevent the motor chamber water and other debris into the bearing, speed bearing wear failure; Bearing cavity filled with oil, the purpose is lubricated bearing, lubrication and cooling mechanical seal, improve bearing under working environment. Almost have customer consultation about silo wall vibrator in the process of running exciting force is too large, sometimes even feel to bin ( Hopper) To shatter the what reason be? Below I give everybody under the analysis of common causes of vibration and the solution: the warehouse wall vibrator selection error, model is too big lead to exciting force is too large. Improper installation, improper installation is another important reason of bearing heating, today, we will hand TWINCAMILQ - PRO bearing to scalp the belly, see the inside structure bearing. Far smaller steel - , between steel cage pocket hole or hole design have locks, and using the elastic and plastic can lock the rolling body, also easy to remove the plastic cage.
