Needle roller and cage assembly
Apart from full complement needle roller sets, the needle roller and cage assembly is the simplest design of needle roller bearing. Needle roller and cage assemblies are of single or double row design and comprise a cage and needle rollers. Since their radial section height corresponds directly to the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements with the very smallest radial design envelope. If the raceways are produced to high geometrical accuracy, high radial run-out accuracy can be achieved.
