TIMKEN bearing if are good of lubrication, and correctly of barrier debris and the moisture, said oil seal should no wear. However, best in open bearing box Shi, check bearing and regularly sexual check oil seal. check near bearing Department oil seal of situation, to ensure they enough to prevent hot liquid or corrosion liquid or gas along axis infiltration bearing, oil seal if has wear should as soon as possible replaced.
High temperature anomalies often indicates that the bearing is. high temperature is also harmful to the lubricant in the bearing. sometimes overheated bearings can be attributed to the TIMKEN bearings lubricant. bearings in more than 125 degree Celsius temperature long-term operation, can reduce the bearing life.
Causes of high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant contains journals, excessive load, TIMKEN bearing damage, inadequate clearance, and oil seal of high temperature friction and so on.
Bearing rolling element and the inner and outer ring raceways are subjected to periodic pulse loads on the surface, resulting in periodic contact stress. When the number of stress cycles after a certain threshold is reached, in the rolling elements or inner and outer ring raceways produces fatigue spalling on the face. If TIMKEN bearing load is too large, will exacerbate this fatigue. In addition, the bearing is not being installed, axis bending, also results in flaking of the Raceway. Bearing Raceway fatigue spalling can reduce the running accuracy of the shaft, body vibration and noise.
TIMKEN bearing raceways, burns on the rolling temper. Burn the cause is lack of lubrication, lubricant quality does not meet the requirements, or degenerate, and bearing Assembly too tight.
TIMKEN bearing raceways and rollers uniform does not appear on the contact surface of the crater, indicate the plastic deformation of bearing. Because of a large static bearing load or shock loading, local stresses exceed the yield limit of material on the surface of the work, which generally occur in low-speed rotation of the bearing.
Cage of metal adhesion due to rolling of the scroll on the body may be stuck in the cage or insufficient lubrication.
Crack of bearing rings may be bearing too tight, bearing foreign or internal ring is loose, inclusive deformation of the bearing, install the bearing surface of poor.
TIMKEN bearing cage fragmentation due to insufficient lubrication of bearings, rolling breaks, the seat tilt.
Washer Raceway serious wear and tear may be a circle out of the hands of foreign objects, insufficient lubricants or lubricant brands do not fit.
