Bearing fault measures to prevent maintenance and dismantling

Bearing fault measures to prevent maintenance and dismantling method source: bearing | last updated: - 2020 08 - 03 bearing fault measures to prevent the maintenance of 1. Such as hear the noise from the bearing parts, first of all, it is important to find the location of the noise occurs. There are many possible noise of moving parts, may also be some rotating parts and no contact with rotating parts. If confirmed is the noise in the bearing, may have been damaged, need to change. 2. Because before the similar working conditions, leading to the invalid on both sides so even a bad one, also recommends replacement in pairs. 3. Bearing is more sensitive, under any circumstances need to use the right methods and with the right tools. In the process of storage and transportation and installation, bearing components cannot be damaged. Need a larger pressure, so I need a special tool. Be sure to refer to the instruction. 4. When installation should be clean and neat environment, tiny particles into will shorten the service life of bearing. Replace when it is very important to maintain a clean environment. Not allowed to use hammer percussion, careful not to fall to the ground, Or similar misconduct) 。 Before installation should also check the status of the shaft and housing, even minor wear can also lead to cooperate with bad, causing damage. 5. Don't attempt to disassemble the bearing or adjust the sealing ring, otherwise you will make the sealing ring damaged cause or dust into the water. Even a sealing ring and inner ring raceway is damaged. 6. Equipped with ABS ring with a magnetic thrust ring, the thrust ring is not influenced by the collision, impact, or a collision with other magnetic field. Take out from inside the box before installation, make them away from magnetic fields, such as using the motor or electric tools, etc. 7. Many of the bearing is sealed, in the whole life period is not to need to add grease. Other not seal such as double row tapered roller must add grease lubrication during installation. Because inside the cavity size is different, so it is difficult to determine how much oil, if oil too much, when bearing rotation, excess oil will seep. Experience in common: during installation, the amount of grease to account for 50% of the gap. Bearing the dismantling of bearing before installation should be clean. Non-standard bearing installation, auxiliary sell straight uniform pressure into, don't use hammer percussion, specifically prohibit direct bearing on tap. When bearing race with a hole loose, should be to repair or replace the bearing seat holes, do not use on the surface of bearing with pitting or pad barely use copper method. Bearing removal should be used when appropriate to pull pull the bearing, do not use a chisel, hammer percussion bearing, etc.
