Four row tapered roller bearings

Four row tapered roller bearings can accommodate combined (radial & axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.


  • Long service life - The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers.
  • Enhanced Operational Reliability - Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
  • Improved Wear Resistance - In particular , SKF explorer bearings are made of extremely clean and homogenous steel and undergo a unique heat treatment, which improve the resistance to wear.
