NTN - Large Bearings

Tapered Roller Thrust Bearings: Screw Down Operations
¡ These bearings are designed to be a full complement roller type and have high static rating load for large axial load
applications.
¡ Inner ring surface is spherical (convex or concave) to allow its circle center to meet the tip of the pressing screw.
¡ For hoisting, bearings are designed to have a hole or bushing at the center of the inner ring, and a bushing on the outer ring.
