Cylindrical roller bearings are precision bearings, precision sorting roller Post-axis circle ribs guide cage, roller and guide shaft ring, can be separated with another bearing rings are separable bearings. Bearing this installation, disassembly is more convenient, especially when the request, the outer ring and the shaft, the housing is interference with the display of its advantages; generally used only for such bearings with radial load carrying loaded guns, and only within, outside circles are single row bearings with ribs with smaller steady axial load or intermittent axial load; Dimensions tired Order of the compared Such bearings have a high load, the background noise and high speed characteristics, ideal for a variety of precision machinery and mining mill machinery. However, in conjunction with such bearings, shaft, rolling body parts require precision machining.
Needle roller bearings (NK, NKS, RNA49, RNA48, NKL, NKLS, NA49, NA48, RNA69, NA69, RNA49 ... RS, RNA49 .. 2RS, NA49 .. RS, NA49 .. 2RS, RNAO, NAO) structure compact, small radial dimension, the large load capacity to withstand greater radial load. Such bearing structure and size series assembled G2 level needle grouping batches diameter variation within 2um In addition to the full complement needle roller bearings are made of high-cage can be precisely guided needle parallel axes .

        Different structures, different types and different direction of the force to withstand, at different speeds, different load, different materials, different occasions applications etc.
       The fundamental difference: the rolling tapered roller bearings tapered roller; rolling needle bearing needle roller;
The above fundamental difference between the structure of the needle roller bearings tapered roller bearing large, tapered roller can bear axial force, and the needle needle roller bearings can only support radial forces in addition to be able to withstand the radial force;
Tapered roller bearings are single row double row and multi-column were applied to different environments and situations;
Tapered roller bearings relative to the needle bearing speed to high;
Tapered roller bearings are generally chosen quality bearing steel and special steel; the thin needle roller bearings selection of steel plate stamping;
In short, these two types of bearings are not the same type of bearing, there are too many different insisted compared with a little far-fetched
Needle roller bearings are composed of long thin needle roller and cage. Cylindrical roller bearings. Is composed of cylindrical roller. The column needle crude, also known as coarse needle.
