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
The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers.
Enhanced operational reliability
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.
Improved sealing performance with less leakage and less frictional heat
Equal load carrying capacity for sealed and open bearings
The optimized and compact seal design enables identical internal design.
Total bearing interchangeability
