- Simplifies the installation as Less Parts .
- To improve the roller load distribution , To reduce wear and prolong service life .
- Due to reduced the Width Tolerance of Inner Ring, Simplifies the rolling roller neck axial positioning ;
- The size is same as the traditional four row Tapered roller with the circle in the middle .
Four-row tapered roller bearings(called rolling mill bearings ) provide maximum capacity in minimum space combining the inherent high-load radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings. Their main application is on the roll necks of rolling mill equipment. All four-row tapered roller bearings are supplied as pre-set matched assemblies with all components identified to ensure correct installation sequence.
Application : Used in steel rolling speed is low to medium speed of rolling mill.
Can appear in addition to bear radial load bearing in the applications of axial load
Four-row bearings provide maximum capacity in minimum space, combining the inherent high-load, radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings.
