Cylindrical Roller Bearings double row, with cage

• Available in avrious designs
• High to very high load ratings
• Available with cylindrical or tapered bore

 

     The friction between the rolling element and the ring flange is small, and it rotates quickly. According to whether the ferrule has ribs, it can be divided into NU and NJ. , NUP, N, NF and other single row rolling roller bearings, and NNU, NN and other double row rolling roller bearings. The bearing has a separable structure with inner ring and outer ring.     
     Double row cylindrical roller bearings with cage can absorb very high radial forces due to the linear contact between rolling element and bearing ring. They are classified into two general designs which differ in flange position on the inner or outer ring. Double row cylindrical roller bearings can be disassembled and are easily installed or uninstalled. They are suitable for medium to high speeds, but they are rigid and cannot compensate angular misalignments.

Features
1. The roller and the raceway are in line contact or repaired offline contact, with large radial bearing capacity, suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.
3. The N type and NU type can move axially, can adapt to the change of the relative position of the shaft and the housing caused by thermal expansion or installation error, and can be used as a free end support.
4. The processing requirements for the shaft or the seat hole are relatively high, and the relative deflection of the outer ring axis after the bearing is installed must be strictly controlled to avoid contact stress concentration.
5. The inner ring or outer ring can be separated for easy installation and disassembly.
