Description
This needle roller bearing carries a solid outer ring with machined needle rollers guided by a standard cage, running without an inner ring. Outside diameter is 33.0 mm, net mass 0.032 kg, with a limiting speed of 17800 1/min and a reference speed of 10700 1/min, corresponding to the light NK series design. The absence of an inner ring keeps the radial section low while allowing a comparatively high load carrying capacity for the given envelope size, provided the shaft seat is hardened and ground to serve as the raceway. The standard cage guides the needle rollers evenly around the circumference, supporting the stated speed ratings under radial load. No sealing or lubrication feature is specified, so relubrication and contamination protection must be arranged externally at the mounting location.
