K series radial needle roller and cage assemblies
radial needle roller and cage assemblies
Needle roller and cage assemblies (needle roller bearing) is independent of the rolling element, its two cage guide surface spacing is broad, can not only accurately guided needle, and can keep the correct position of the needle. This kind of bearing is suitable for the shaft and hole can be used as a race, only the shaft and bearing seat hole groove processing to the specified size accuracy and geometric accuracy, can ensure minimum space high rotation accuracy.
As for Model K, K...D radial needle and retainer assembly, this kind of bearing only has a group of radial needle and retainer assembly. With small outside diameter size, it is suitable for the parts, where the radial sizes are specially limited, used for bearing the radial load. Model K...ZW, K...ZWD radial needle and retainer assembly is the double row radial needle and retainer assemblies.
Part of our K series catalogue :
(1-1) K single-row radial needle roller and cage assembly
(1-2) K...ZW double-row radial needle roller and cage assembly
(1-3) K... D partial single-row radial needle roller and cage assembly
(1-4) K...ZWD double-row radial needle roller and cage
