IKO thrust cylindrical roller bearing which should be paid attention to when using

1, selection of shaft and the bearing chamber tolerance and control after IKO bearing pressure into the bearing should be flexible rotation without blocking. If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade. Such as thrust cylindrical roller bearing pressure into the shaft by hand after the rotation has obvious 'sasha vujacic' feeling, may be the shaft or shaft roundness tolerance is too big. When control the shaft and the bearing chamber tolerance so also want to control the roundness, at present many domestic manufacturers to control the tolerance, not to control the roundness. 2, bearing assembly way for IKO bearing is high precision products, such as improper assembly is easy to cause damage to bearing channel, result in bearing damage. Thrust cylindrical roller bearing in the assembly shall have a dedicated mold, not casually, only small circle of stress when pressure into the shaft, pressure can force the circle circle. Require the use of pneumatic or hydraulic assembly, lower die when being connected to outside the level state, if there are any tilt can lead to bearing channel due to mechanical damage, and make the bearing guide ring. 3, foreign material to prevent bearing assembly when loaded on the rotor to do dynamic balance will be generated when the dynamic balance of iron into easily IKO bearing inside, so it is best to install bearing before do dynamic balance. There are some manufacturers in order to convenient assembly, assembly in bearing indoor coated with some oil or grease lubrication effect, but usually operators good amount of it is hard to control, if oil or grease in the bearing interior storing up more, the thrust cylindrical roller bearing rotates along axis to the bearing inside easily. Bearing chamber it is best not to apply oil or grease, if must apply to control shall not be storing up in bearing interior. 4, paint, rust preventive rust paint is characterized by multiple in sealing type motor, the motor sound is very good, when it is assembled but put some time in the warehouse, the motor sound has become very big, remove the IKO bearings have serious rust phenomenon. Before a lot of manufacturers will think is a problem of cylindrical roller thrust bearing, through our continuous publicity, motor factory now have realized mainly is a question of insulating varnish. Acid varnish comes out of the problem is mainly due to the formation of corrosive substances under certain temperature and humidity, the bearing channel after corrosion result in bearing damage. The problem now is only to choose good insulating paint, after drying and ventilation assembly after a period of time.
