NSK work rolling of tapered roller bearing load

NSK bearing fatigue peeling occurs if, after running for a long time, should be regarded as natural damage, if you use medium or tapered roller bearings occur early, shall be considered as non-natural peeling, then, should identify the causes of peeling.
Major causes of non-natural peeling as a result of NSK bearing types caused by improper or due to improper installation.
(1) due to improper type selection of tapered roller bearing large axial loads are causing spalling in case selection of bearings, peeling may occur early. Spalling occurs mainly in the Raceway, which makes rolling the scroll ball direction of trajectory to move, even roller ball, and finally enable Raceway severe spalling damage occurred. Measures to prevent such damage is according to the working conditions of reasonable selection of bearings NSK bearings.
Vibration injury can be said to be quite sensitive to NSK, indentation, rust, cracks, spalling, are reflected in the measurement of vibration, such as wear. Therefore, through the use of special NSK bearing vibration Measurer (frequency Analyzer, etc) can measure the size of the vibration, through frequency cannot be inferred from specific situations of exception. Measured value due to conditions of use of tapered roller bearings or sensor installation locations vary, therefore require prior to analysis and comparison of measurement values of each machine are determined benchmarks.
Thus continuity is necessary to monitor the temperature, whether measured itself or other important parts. If operating conditions do not change case, any temperature changes may have occurred at fault.
Frequently expressed NSK bearings in high temperature anomalies. High temperatures may also be harmful to the bearing lubricant. Sometimes tapered roller bearing overheating could be attributed to lubricant. If more than 125 ℃ temperature long-term continuous transfers to reduce life expectancy. Cause of the high temperature including: lubrication is insufficient or excessive lubrication, lubricant. Contains impurities, excessive load, NSK bearings damaged rings, insufficient clearances, and oil have high friction and so on.
