This needle roller bearing carries radial load through a single row of needle rollers guided by a standard cage, with an outside diameter of 120.0 mm and a net mass of 485.5 g. It belongs to the light series, giving a compact cross-section for its diameter class. Limiting speed is rated at 4600.0 1/min, with a reference speed of 3150.0 1/min. The standard cage guides and evenly spaces the needle rollers, keeping friction low and supporting stable running at the rated speeds. As a NK-type bearing, it uses a separate inner ring or a hardened shaft as the inner running surface, which keeps radial section height low for a given load capacity. The light series construction makes it suited to applications where radial space is limited but the full needle complement of a heavier series is not required.
