HZV 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.
1.Description of spherical roller bearing:
1)Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings have cylindrical or tapered bores.The symmetrical barrel rollers orient themselves freely on the concave outer ring raceway.
2)This type bearings are self-aligning and consequnently insensitive to misalignmient of the shaft relative to the housing and to shaft deflection or bending.
3) The bearings are leading in design with many series such as 213..-, 222,
230, 239, 240, , 241,223, , 231, 232, 233, 241
4)The differences of the bearings include the arrangement of the floating guide ring and the design of the inner ring and/or cages.
