YFB produce the following combined radial-thrust bearings inclued:NKIA,NKIB,NX,NKX,NKXR,RAX700,RAXF700,RAX400,RAX500,RAXPZ400,RAXZ500

Needle and ratainer assenbly,needle bearing and drawn cup needle roller bearings are all moving tip bearings.They can be used as positioning bearing with combined with stop thrust rings or under small load at low speed and being fully lubricated.Other positioning bearing always have the problem of much space occupied.

Combined YFB needle bearings are single directional positioning bearings or the positioning bearings with minimum radically sectional height.If the centripetal needle bearings are used with thrust ball bearings or cylindrical roller bearings in combination,the applicable range will be greatly expanded.The combined needle bearings are mainly used in transmission engineering and tooling machines such as the bearing in the main shaft of a drill press,drill sleeve ,positioning central shaft,worm,spanner teeth head and so on and so forth.
