1.Cylindrical roller bearings
Rolling element is a cylindrical roller bearing to the heart
Cylindrical roller and raceway contact bearings. Load capacity, mainly bear radial load. Rolling ring wall with small friction, suitable for high-speed rotation. According to ring without ribs can be divided into NU, NJ, NUP, N, NF, etc. Single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is the inner, outer separable structure.

2.Inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as a free-end bearings. In the inner and outer side of a double wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, or copper alloy machined solid cage. But there is a polyamide forming cage.

2.Cylindrical roller bearings Features
1 roller and raceway contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load. 
2 small friction coefficient, suitable for high speed, speed close to deep groove ball bearings.
3. N type and NU type can move axially, to accommodate misalignment due to thermal expansion or of the shaft and the housing due to changes in relative position, can be used for supporting the free end.
4 pairs of shaft or housing bore machining higher, bearing outer ring axis relative deflection after installation should be strictly controlled to avoid contact stress concentration.
5 inner or outer ring detachable, easy installation and removal.

3.Characteristic

1.High radial load capacity,is suitable for heavy load and impact load.

2.Small friction, suitable for high speed,the limiting Speed is close to Deep Groove Ball Bearings

3.N,NU series can adapt to high temperature and allow error during installation.

4.inner ring and outer ring are separable,easy to install and take down

4.Mainly use

Large and medium-sized motor, locomotives, spindle, internal combustion engine, generator, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc.
