HZK spherical roller bearing:
Advantages of bainite quenching:
Improve the dimensional stability of the bearing
Improve the mechanical properties of the bearing (bending strength, impact toughness)
After quenching, the surface of the parts presents compressive stress, thereby improving the service life and reliability of the bearing.
It can be used in railways, rolling mills, mines, coal mining and drilling rigs with harsh working conditions and high impact loads.
Spherical roller bearing with two rows of rollers, mainly to bear radial load, but also can withstand any direction of the axial load.High radial load capacity, especially suitable for heavy load or vibration load, but cannot bear pure axial load.The raceway of the outer ring of this kind of bearing is spherical, so its centering performance is good and it can compensate the coaxiality error
Applications: papermaking machinery, reduction gear, railway vehicle axle, rolling mill gear box bearing, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial reducer, vertical centering bearing with seat| Model Dumber | Internal Diameter(mm) | External Diameter(mm) | Thickness(mm) |
