NJ304 Bearing 20x52x15mm

1.NJ304 cylindrical roller bearings

2.size:20*52*15mm

3.material:GCr15

4.cage :steel  cage

5.type:NU,N,NJ,NUP series

6.precision class:P0,P6,P5,P4,P2

7.features

1. The rollers and raceway for the line contact or offline access, radial load capacity is large, suitable for under heavy load and shock load.
2. The friction coefficient is small, suitable for high speed, the limit speed close to the deep groove ball bearings.
3. N and NU type axial movement, can adapt shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing.
4. On the shaft or hole processing the demand is higher, bearing outer axis relative deflection after installation to kept under strict control, so as not to cause contact stress concentration.
5. Inner ring or outer ring separable, easy to install and disassemble.

8.application:Large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc
