This needle roller cage assembly guides a single row of needle rollers within a JN-type cage, offering a width of 13.0 mm and a net mass of 6.2 g. It supports a limiting speed of 22900 1/min and a reference speed of 14100 1/min, making it suitable for compact radial arrangements where the shaft or housing surface serves as the running track. Being a cage-guided needle roller set rather than a complete bearing, it requires a hardened and ground shaft and housing bore to form the full bearing arrangement. The design keeps radial section low while maintaining rolling element guidance, and it depends on adequate lubrication supplied externally, since no integrated sealing or grease reservoir is part of this component.
