by 
Strong metallic sound:
1. Abnormal load: select Use Of appropriate assembly clearance and preload
2. Poor assembly: improve the Use Of machining accuracy of the shaft and improve the installation method
3. Insufficient lubricant: Use Of supplement or use appropriate lubricant
Regular tone:
1. Corrosion, indentation and scar of channel caused by foreign Use Of matters: clean relevant parts and use clean grease
2. Channel peeling: fatigue wear, replace IKO bearing
Irregular abnormal sound:
1. Foreign matter intrusion: clean relevant parts and use clean Use Of grease
2. Excessive clearance: pay attention to fit and select Use Of appropriate clearance
3. Steel ball damage: steel ball fatigue peeling or foreign matter Use Of jamming, replace IKO bearing
Abnormal temperature rise:
1. Excessive lubricant: reduce lubricant
2. Insufficient or unsuitable Use Of lubricant: add lubricant or select appropriate lubricant
3. Creep of fitting surface: correction of fitting surface of outer diameter or inner diameter of IKO bearing
4. Residual clearance is too small: it is mainly caused by too much shaft interference or too much negative hole tolerance
5. IKO bearing hole misalignment: misalignment causes early wear and damage of IKO bearing
Large rotary vibration of shaft:
1. Spalling: fatigue spalling, replace IKO bearing
2. Poor assembly: improve the machining accuracy of the shaft and improve the installation method
3. Foreign matter intrusion: clean relevant parts and use clean grease
Large lubricant leakage and discoloration:
1. Excessive lubricant: reduce lubricant
2. Foreign matter intrusion: clean relevant parts
1、 Function of IKO bearing lubricant
A layer of lubricating film capable of bearing is formed on the contact surface
dissipate heat
As an additional seal of IKO bearing, it can resist external solid and liquid pollutants (grease lubrication)
Reduce running noise and rust
2、 IKO bearing lubrication steps and methods
Rolling IKO bearings can be lubricated with grease or oil.
The amount of lubricant and the method of lubrication are determined by the following factors:
Operating conditions
IKO bearing type and size
Surrounding structure
Lubricant supply mode
Lubricants containing additives – ina uses lubricants containing additives, including:
Anti rust and anti aging materials.
Additives can reduce wear if lubrication conditions are poor. A layer of reaction film is formed on the relevant surface to play a protective role. This evil additive composition may not be fully effective in some cases over the entire temperature and load range.
