This needle roller cage assembly carries a single row of needle rollers positioned in a JN cage, with an axial width of 10.0 mm and a net mass of 4.69 g. It is rated for a limiting speed of 23600 1/min and a reference speed of 15200 1/min, giving it a compact radial section suited to applications with restricted installation space. Being a cage assembly rather than a complete bearing, it requires a hardened and ground shaft and housing bore to form the running surfaces, with the cage guiding and spacing the needle rollers to reduce friction and maintain even load distribution around the circumference. The design allows for direct mounting against adjacent shaft and housing raceways, keeping radial dimensions minimal while supporting the stated speed ratings.
