Cylindrical roller bearing belong to precision bearings, precision separation of the roller mail axis of the circle raised edge guide, by maintains a, roller and guide the shaft circles, and another bearing collar separation, belongs to the separable bearing. These bearings installation, remove more convenient, especially when asked to inner and outer shell with shaft, is made more when the advantages with shows; Only commonly used for such bearing with radial load were armed, only the inner and outer with the bearings are raised edge with the smaller constant axial load or larger intermittent axial load; The same size and shape of the other tired than bearing, these bearings with high load, the noise and the characteristics of the high speed, very applicable and all kinds of precision machinery and mining mill machinery. But with this kind of the shaft of the bearing fits, roller and related parts need to be precision processing and into.bearing factory
Needle bearing (NK, NKS, RNA49, RNA48, NKL, NKLS, NA49, NA48, RNA69, NA69, RNA49... RS, RNA49.. 2 RS, NA49.. RS, NA49.. 2 RS, RNAO, NAO) compact structure, radial of small size, and the load capacity, withstand the big radial direction load. Such bea ring a variety of structure and size series, are assembled G2 level needle, group batch of diameter changes in the amount within 2 um, except full pack needle bearing outside, all adopt high sexual maintains a, able to correctly guide needle parallel axis.
Different structure, different types, different direction of holding capacity, different speed, load is different, the material is different, the application in different occasions, and so on
Fundamental difference between: circular cone roller bearings rolling body is tapered roller; Needle bearings rolling body is the needle roller;china bearing supplier
Above fundamental decide the difference between the structure of the tapered roller bearing relative needle bearing, tapered roller in addition to bear radial force outside can handle axial force, and needle needle bearing can only bear radial force;
Tapered roller bearing points more than double row and single column, were applied to different environment and occasions;
Tapered roller bearings relative to needle bearing work to high speed;
Tapered roller bearings are generally choose high quality bearing steel and special steel; And the thin needle bearing is to choose stamping steel and become;
All in all, these two kinds of bearings is not the same type of bearing, there are too many different, don t want to compare s really far-fetched
Needle bearing is long thin needle and maintains a composition. Cylindrical roller bearing. Is composed of cylinder and roller. Column than needle thick, also call the thick needle.bearing factory in china
