Usually, through the working temperature the bearing fault recognition thick, rolling machine use four row circular cone roller bearings, stands of use double row cylindrical roller bearing, the level QianChui rolling mills and rolling mill use the same type of bearing.

No matter the four row circular cone roller bearings, cylindrical roller bearings or double column, the basic structure of the traditional and the rolling mill bearing similar, bearing appear the following, speak the weaknesses of do not continue to use but the design of the various parts of the full consideration of the lubrication and cooling problems, namely, and outer circle, every circle (to four row circular cone roller bearings speaking), maintains , roller (to double row cylindrical roller bearing speaking) open many trough, hole, etc. So, chamfer, hole formation of lubrication, cooling channels and housing, Japan bearings enterprise production pattern and maintain quality brand roll on the channel is formed a reliable lubrication and cooling system, plus good sealing device, the bearing can be in a state of high speed high pressure stable operation.
Although the manufacturer provide the contour of the rolling mill bearing design style is different, but all have one thing in common, extension running bearings temperature on the high side that the main reason of the circle of inner wall thickness of the same specification relative to the ordinary bearing a bit thicker, outer ring is relatively thinner.
