The type and structure of high-speed wire rod mill bearings
High-speed wire rod mill bearings, four-row tapered roller bearings and double row cylindrical roller bearings two son. In general, coarse, medium mill using four-row tapered roller bearings, finishing mill double row cylindrical roller bearings, horizontal mill and hammer mill using the same type of lead bearing.
Whether four-row tapered roller bearings or double row cylindrical roller bearings, the basic structure is similar to the conventional rolling bearing, but various parts of the design fully consider the lubrication and cooling issues, namely the inner and outer rings, spacers (on four tapered roller bearings concerned), cage, rollers (for double row cylindrical roller bearings concerned) has opened a lot of slots, holes and so on. Thus, slots, holes are formed lubrication, cooling channels and bearing, roll on the channel to form a reliable lubrication and cooling systems, coupled with a good seal, so that the bearing can be stabilized at high pressure state to run.
Although various vendors provide high-speed wire rod mill bearing design style is different, but all have one thing in common, that is, the wall thickness of the inner ring relative to the same specifications of the ordinary bearing little thick, the outer ring is relatively thinner.
