This needle roller bearing carries a separable design with a machined outer ring and a full complement of needle rollers guided by a standard cage. The outside diameter is 53.0 mm, net mass is 0.132 kg, limiting speed reaches 10700 1/min, and the reference speed is rated at 6300 1/min. The standard cage keeps the rollers evenly spaced and reduces friction losses during rotation, which supports running at the rated reference speed without exceeding thermal limits. The compact radial section typical of the NK43/30-XL design allows fitting into tight housing bores where radial space is limited, while the stated limiting speed defines the upper mechanical boundary for shaft rotation under proper lubrication.
