two rows of symmetrically arranged spherical rollers, the outer ring has two raceways,Form an angle with the vertical axis of the bearing.
The rolling elements are radial rolling bearings with cylindrical rollers. Cylindrical Roller Bearings，The internal structure adopts rollers arranged in parallell
Tapered roller bearings are separable bearings, and both the inner and outer rings of the bearing have tapered raceways.
Thrust roller bearings are used to bear the combined axial and radial loads mainly under axial load, but the radial load shall not exceed 55% of the axial load.
Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time.
Spherical bearing with seat is a kind of bearing unit that combines rolling bearing and bearing seat
