Combined bearing is a bearing while the bearing structure of the two above combination of rolling bearings, combined bearings are radial section height smallest positioning or unidirectional locating bearing, its use in transmission engineering and machine tools such as: drill spindle centering axis, drill sets, worm, CNC machine, die head spindle bearings and similar applications. If NKXR / ZARN needle roller and cylindrical roller thrust bearings, NKX / NX needle and thrust ball bearings, NKIA / NKIB needle roller and angular contact ball bearings.
Combined needle roller bearing is a bearing while the bearing structure of the two above combination bearings, combined needle roller bearing is a radial section height of the smallest one-way positioning or locating bearing, its use in transmission engineering and machine tools such as: drill spindle centering axis, drill sets, worm, CNC machine, die head spindle bearings and similar applications. If NKXR / ZARN needle roller and cylindrical roller thrust bearings, NKX / NX needle and thrust ball bearings, NKIA / NKIB needle roller and angular contact ball bearings. Gear reducer bearings are widely used in heavy equipment manufacturing gear is widely used transmission and speed control device, in modern scientific research, defense, transportation, metallurgy, chemical industry and other economic infrastructure is widely used in many fields. Reducer bearings generally use tapered bearings and deep groove ball bearings.Stud type track rollersRoller bearing
Curve roller bearings (aka Bolt roller bearings) KR series, KRV series, NUKR series bolt type roller bearing is G20CrMo bolt shaft through HVI ≥ 664, effective hardened layer 1.3mm refined, and then by the group as a roller roll Road bolt and a thick-walled outer ring combinations. A shoulder bolt shaft and the pressure in the screw ring formed on the end face of the outer two lateral direction along the guide surface. When the curve at the level of the roller or the roller moving on the cam disc, due to the elastic deformation of the outer ring, the roller to increase the internal stress. Therefore, this work applies to the case of the rated load curve wheel column, select
