needle roller and cage assemblies ntn needle roller and cage assemblies this needle roller and cage assembly is one of the basic components for the needle roller bearing of a construction wherein the needle rollers are fitted with a cage so as not to separate from each other the use of this roller and cage assembly enables to design a compact and lightweight construction by utilizing a shaft type of needle roller and cage assembly cage type applied shaft diameter mm or a housing as the direct raceway surface without using inner ring and outer ring the needle rollers are guided by the cage more precisely than the full complement roller type hence enabling high speed running of bearing in addition its rigidity and load capacity are high for the specific space composition of nominal bearing number nominal bearing number code items and respective dimensions kkskt2 machined ring type polyamide resin type k 20 3 285 24 10 s tail code width inscribed circle diameter 20 24 k20 24 10s roller s
