Description

The 385/383A NTN is a single-row tapered roller bearing featuring conical raceways and tapered rollers, designed for combined high radial and axial loads in one direction. It consists of a cup (outer ring) and cone (inner ring, cage, and roller set), making it easy to assemble or disassemble. These open-design bearings are typically mounted in pairs for optimal performance and can be arranged in X, O, or tandem configurations.
