YDTech® manufacturer of NAV4006,RNAV4009,RNAV4017, NAV4860 full complement needle bearings! supplier of RNAV4904,NAV4928,RNAV4848,NAV4838,RNAV4013, NAV400,RNAV4005 rolling bearings.

NAV (full complement needle roller bearings): NAV bearings are full complement needle roller bearings without an inner ring. "NAV" stands for "N" (needle roller bearing), "A" (full complement of rollers), and "V" (with inner ring). these bearings have a complete set of needle rollers without a cage, allowing for maximum load-carrying capacity within a given space.

RNAV (full complement needle roller bearings): RNAV bearings are similar to NAV bearings but have an outer ring with a lubrication groove and holes. The prefix "RNAV" stands for "R" ( without inner rings or without outer rings.) only suitable for NA type needle roller bearings.

"N" (needle roller), "A" (full complement), and "V" (with an outer ring lubrication groove and holes). the addition of lubrication features on the outer ring enhances the bearings' ability to distribute lubricant and reduce friction.

full complement needle roller bearings are used in applications where high radial load-carrying capacity and compact design are essential. They are commonly found in heavy machinery, automotive transmissions, construction equipment, and various industrial applications. These bearings are particularly suitable for applications with limited space or where shaft misalignment may occur.

HK...RS HK...2RS BK...RS Series needle roller bearings The sealed drawn cup needle roller bearing is mounted with sealing lip. In general, the sealing lip can protect bearing from penetration of impurities and leakage of lubricating grease.

F FH MF MFH FY MFY series needle roller bearings, this kind bearing consists of full of needles extending to outer raceway, thus bearing high load. It is applied to the situation where the devices mounted with needle roller bearings run in swinging.
