This needle roller cage assembly carries a single row of needle rollers guided by a JN cage, with a width of 17.0 mm and a net mass of 8.42 g. The design allows a limiting speed of 25000 1/min and a reference speed of 17300 1/min, giving it a defined rotational capacity within these mechanical limits. The needle roller cage assembly K14X18X17-A/0-7 requires a hardened and ground shaft and housing bore to serve as running surfaces, since it consists only of the rolling elements and cage without integrated rings. This construction results in a low radial section height and reduced mass, which supports operation at the stated speed values while keeping the assembly compact within its 17.0 mm width.
