This needle roller cage assembly guides a single row of needle rollers within a 14 mm bore, 18 mm outside diameter, and 15.0 mm width envelope, with a net mass of 5.0 g. The TV cage design retains the rollers and controls their spacing, allowing the assembly to run at a limiting speed of 25000 1/min and a reference speed of 17400 1/min. The compact cross-section keeps radial space to a minimum while the cage-guided rollers provide low friction rolling contact against a hardened shaft and housing bore that must supply the running surfaces. As a bearing-and-shaft type arrangement without integral rings, it depends on correctly dimensioned mating surfaces and lubrication supplied by the surrounding assembly to reach the stated speed values.
