1 . ) Cylindrical roller bearings is generally only used to bear radial load, compared with the same size deep groove ball bearings, have bigger radial load capacity, limit rotational speed is close to deep groove ball bearings, but with this type of bearing shaft, shell hole processing the demand is higher, allow the axis of the inner ring and outer ring axis inclination is small (2 ° - 4 °), two axis tilted as beyond the limit, The contact between the roller and the ring raceway will deteriorate, seriously affecting the load capacity of the bearing and reducing the service life of the bearing. Therefore, if such bearings need to be installed in the main engine parts under axial load, they can only be used if other types of bearings are used to bear axial load at the same time.

Techinical Specification Roller bearing NJ307 :

ASSOCIATED PRODUCTS: Angle ring HJ 307 EC

2 . ) Cylindrical roller bearings have below types:

N type:
The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.

3 . ) Application:

Large motors, Machine tool spindles, Engine front and rear support shafts, Train and bus box shaft support, Diesel engine crankshaft, Automobile and tractor gearbox, Internal combustion engine, Generator, Gas turbine, Reducer, Rolling mill, Vibrating screen and lifting and transportation machinery
