Insufficient grease may change color. in addition, if the temperature is abnormal, the performance of the oil and fat will also change greatly, so that there will be discoloration. if the temperature is high, it will carbonize. the color becomes darker. 3. during the operation of the bearing, impurities are mixed in the grease.
For this reason, hightemperature bearings make a superficial review of common bearing failure modes and mechanisms, in order to play a role of attracting a lot of attention. bearing failure mechanism: contact fatigue failure. contact fatigue failure refers to the failure of the bearing working surface under the effect of alternating stress.

High bearing temperature may also be considered as a contributing factor to fatigue damage. as temperatures increase, the fatigue strength of bearing materials decreases. the lubricating oil must be filtered or replaced. in addition to filtering or replacing the oil, the entire bearing assembly, oil reservoir and piping should be flushed and.
In combination with a grinding mill or the like having a trunnion supported by a stationary bearing structure to define a ''''free bearing'''' which permits axial contraction of the grinding mill during the coolingoff period after mill shutdown, a high pressure lubrication system including a high pressure pump for applying hydrostatic pressure to the ''''free bearing'''' during the mill.
