  Tapered Roller Bearings

30304 J2/QTapered roller bearings mainly bear the combined radial and axial loads mainly in the radial direction. The bearing capacity depends on the raceway angle of the outer ring, and the larger the angle, the greater the bearing capacity. Widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
