What are the main parts of the cone roller bearings?
Whether the four row tapered roller bearings or cylindrical roller bearings, the basic structure and the traditional rolling mill bearing similar bearing following talks about the defects cannot continue to use but the design parts of the full consideration of the lubrication and cooling problems, namely in the inner ring and the outer ring, a spacer ring (for the four column tapered roller bearings are concerned), cage, roller (of double row cylindrical roller bearings for) there are many open grooves and holes etc..
So, groove, hole forming lubrication, cooling channel and the bearing seat and Japan bearing enterprise production pattern and maintain high-quality brand on the roll channel is composed of a reliable lubrication and cooling system, coupled with good sealing device, local operation makes the bearings can be stabilized in high speed and high pressure in the state.Although the design style of high speed wire rolling mill bearing manufacturers offer different, but have one thing in common, the main reason is the high temperature extension operation of the bearing inner ring wall thickness is equivalent to the ordinary bearing thickness, the outer ring is relatively thin.
Rolling mill imported bearings has four columns of the tapered roller bearings and double row cylindrical roller bearing two under normal circumstances, the fault identification of bearing by the working temperature of the roughing and intermediate mill using four row tapered roller bearing, rolling mill with double row cylindrical roller bearings, bearing level and plumb mill mill of the same type.
