Tapered roller bearings
Imported bearings at low prices
Tapered roller bearings can be separated, and the assembly composed of the inner ring and roller cage and the outer ring can be installed separately. Corrected contact lines at the roller and raceway contact reduce stress concentrations. Tapered roller bearings can bear large radial loads and axial loads. Since the tapered roller bearing can only transmit axial load in one direction, in order to transmit the axial load in the opposite direction, another tapered roller bearing installed symmetrically is required
The most commonly used tapered roller bearing is Single row tapered roller bearings. In recent years, small-sized double-row tapered roller bearings have also been used in the front wheel hubs of cars. Four-row tapered roller bearings are used in heavy machines such as large hot and cold rolling mills.
Structural features
The type code of tapered roller bearings is, and tapered roller bearings are separate bearings. In general, especially within the size range mentioned in "Rolling Bearings Radial Bearing Tolerances", the outer ring and inner components of tapered roller bearings are 100% interchangeable.
The angle of the outer ring and the diameter of the outer raceway have been standardized and specified as the same as the overall dimensions. Changes during design and manufacturing are not allowed. As a result, the outer ring and inner components of tapered roller bearings can be interchanged worldwide.
Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearings, they have larger load-carrying capacity and lower limit speed. Tapered roller bearings can withstand axial loads in one direction and can limit axial displacement of the shaft or housing in one direction
