Cylindrical roller bearing type is much and different

As we all know cylindrical roller bearing type is much and different,this is some detail of cylindrical roller bearing type for your reference:
Cylindrical roller bearing can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings according to whether the ring has a flange or not.  The bearing is a detachable structure with inner ring and outer ring.  
The rolling body is the centripetal rolling bearing of cylindrical roller bearing type.  The inner structure of cylindrical roller bearing type adopts rollers to be arranged in parallel, and there is a spacer or isolation block between rollers, which can prevent the tilt of rollers or friction between rollers, and effectively prevent the increase of rotating torque.  

Characteristic for cylindrical roller bearing type:
1.Roller and raceway are in line contact or downline contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.  
2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.  
3. N type and NU type can be moved in axial direction, can adapt to the change of the relative position between the shaft and the shell caused by thermal expansion or installation error, can be used as free end support.  

4. The processing requirements for shafts or seat holes are high. After bearing installation, the relative deviation of the outer ring axis should be strictly controlled to avoid contact stress concentration.  
5. The inner ring or outer ring can be separated, easy to install and disassemble.
