Bearing features of four row tapered roller bearing 331907

Long service life: 331907 bearings provides optimal load distribution over all four rows of rollers
Enhanced opertional reliability:Optimized surface finish on the contact surfaces of the rollers and raceways of 331907 supports the formation of a hydrodynamic lubricant film.
Improved wear resistance: 331907 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 of bearings 331907ensures 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.
Axial space-saving and cost-effective solution for roll necks: the roll necks can be relatively short, no separate axial bearings are required and identically designed chocks can be used on both sides of the roll.
Simple axial location on roll necks:tighter inner ring width tolerances of bearings 331907 facilitate the tolerancing and dimensioning of surrounding components.
