Tapered roller bearing

Four-row tapered roller bearings 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 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. Improved sealing performance with less leakage and less frictional heat The optimized seal design ensures high protection against external contamination but keeps friction and frictional heat low. This seal design also provides a better retention of lubricant, minimizes environmental impact and reduces maintenance costs.
