Cleanliness is important for heating of high temperature bearings

In the popular position, high-temperature bearing grease filling, always goes beyond the practice of intervening directly in the lubrication of the demand, and INA bearing cover on the full cavity and on the edge of rolling elements constitute a profile. In the process, because of excess grease resistance, INA bearing temperature rise quickly. Although most of the excess grease in the early running was out, and squeezing roller attachment for grease may still be migrated between roll shift rolling into the road.
These early stages in INA bearings run, most of the grease quickly (in less than a minute) crowding the Raceway, and accumulate in the grease in the bearing migration into reincarnation, being little is excreted. High temperature bearings temperature continues to rise until the excess grease is discharged so far, can be called a grease collection phase, according to INA bearing grease quality, quantity and other elements of the structure, this period of time may last a dozen minutes, and even a few hours.
A, on the life of high temperature bearing:
High temperature bearings by cleaning effect on bearing life considerably, bearing special tests have been performed by the company for this purpose, with the result that their differences for a few times and even dozens of times to more than double. Bearing cleaning more, longer life and other people's experiments show that different cleanliness of the lubricant to the ball bearing life considerably. Therefore, improve the cleanliness of the lubricant can extend the life of INA bearing, in addition, lubricant with dirt particles control 10um, bearing life into several times growth.
B, vibration and noise impacts:
Vibration effects: high-temperature bearing test results show that cleanliness seriously affect INA bearing vibration levels, especially high-frequency vibrations more visible. Clean bearing vibration velocity values for high low, especially in the high frequency band.
C, the effect on the lubricating properties of:
High temperature bearings drop in cleanliness, affect not only the lubricant film formation, also cause spoilage and accelerate their ageing of grease, thus affecting the grease lubrication performance.
