Features of Single row tapered roller bearings NTN 329X-320X-302-322-303-303D-313X-323 series (contains model 32311U)

Tapered roller bearings are designed so the tapered vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the centerline of the bearing.
The tapered rollers are guided by the compound force of the inner and outer raceway surfaces which keep the rollers pressed up against the large rib on the inner ring.
A large variety of these bearings, including single, double, and four row arrangements, are available in both metric and inch series.
Application: Pumps/ air compressors/ industrial rolling machines/ precision machining machines
