Tapered roller bearings can be separated, and the assembly composed of the inner ring and the roller and cage together and the outer ring can be installed separately.
The modified contact line at the roller and raceway contact can reduce stress concentration, and tapered roller bearings can withstand large radial and axial loads.
Because tapered roller bearings can only transfer unidirectional axial load, it is necessary to transfer the axial load in the opposite direction and another tapered roller bearing mounted symmetrically.
Hot rolling and expanding technology for large bearing forgings with outer diameter below 6500mm, with chemical heat treatment impermeability technology, bearing isothermal salt bath martensite, bainite quenching technology.
It has advanced CNC production connection for car, mill and superfine, and advanced technology such as compound grinding and double raceway grinding. The product precision can reach P5 level or above.
Master the physical vapor deposition coating technology of high-end bearings, surface nitriding treatment, vacuum vulcanization treatment and other surface modification technologies. The application of this technology solves the early fatigue problems such as rolling surface wear and burn caused by the absence of instantaneous oil film under instantaneous high-speed and large load conditions.
With three coordinates, profilometer, roundness meter and other testing equipment, the measurement accuracy can reach 2 microns.
Bearing type test with maximum outer diameter of 3.3 meters can be carried out.
