IKOBearing running inspection and troubleshooting
In the popular situationNSKFilling amount of imported bearing grease，The practical requirements for direct involvement in lubrication are always exceeded，In the cavity of the filling frame and the rolling mill bearing cover，And form an outline around the rolling body。In the process，Because of the resistance of excess grease，The bearing temperature rises quickly
High temperature bearing is an important moving part of automobile。High temperature bearings are responsible for reducing the friction resistance of the chassis during operation，The heavy duty of keeping the car running properly。If the high temperature bearing fails，It may cause noise、IKOBearing heating phenomenon，Especially the front wheels，It can easily lead to dangerous phenomena such as loss of direction
whenskfWhen the bearing temperature rises，First determine whether it is a mistake，If the temperature of the fully loaded cylindrical roller bearing does rise，The following should be done： (1).Check cooling water pressure，Water flow and piping system is normal。If the water is low, the filter may be blocked，Can not be dealt with in time，Stopable processing，When its confirmed to work，Put back into service。
The removal of imported bearings should be carried out as carefully as the installation。Be careful not to damage the bearing and parts，Especially the removal of interference fit bearings，Difficult to operate。
The planar thrust bearing is mainly subjected to axial load in the assembly，Its wide application。Although thrustSKFBearing installation operation is relatively simple，However, there are still many errors in actual maintenance，namelySKFThe tight and loose rings of the bearing are installed incorrectly，Result inSKFBearing failure，The journal wears out quickly。
The separation bearing of the clutch of internal combustion forklift works frequently，The damage times account for a large proportion of forklift truck failures，If the driver did it right，Timely maintenance，This bearing can be used3About a month，But it has to be replaced in the middle repair
Transverse grinding during grinding，When the table longitudinal stroke ends，Grinding wheel spindle or table for a transverse feed，At this time, the thickness of the metal layer ground by the grinding wheel is the actual amount of back cutting，After the first layer of metal on the workpiece is worn off，The grinding wheel is re-applied to vertical feed，The grinding head is reversed to continue the transverse feed，Grind off the second layer metal allowance of the workpiece，So many reciprocating grinding，Until the entire margin is removed。
The lubricating oil turns dark black after deterioration、There is a lot of foam and emulsification，Finger grind，No stickiness，Astringent or smelly，Drops appear dark brown on white test paper，No yellow infiltrating area or many black spots。If not replaced in time, it will accelerate the wear of parts，Affect service life，There may even be security incidents，therefore，It is especially important to check the lubricating oil frequently for deterioration and replace it in time
High speed precision angular contact ball bearings，It is mainly used for high-speed rotating occasions with light load，High bearing accuracy required、High speed of revolution、Low temperature rise low vibration and certain service life。
