Four-row tapered roller bearings can accommodate combined (radial and axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.
Bearing features
Depending on their design, four-row tapered roller bearings provide the following main features and benefits:
Long service life
Enhanced operational reliability
Improved wear resistance
Improved sealing performance with less leakage and less frictional heat
Equal load carrying capacity for sealed and open bearings
Total bearing interchangeability
Separable mounting and simpler inspection
Axial space-saving and cost-effective solution for roll necks
Simple axial location on roll necks
