Tapered roller bearing

NTN tapered roller bearing refers to a radial thrust rolling bearing with tapered rollers as the rolling element. There are two types: small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial loads, which are mainly radial loads. It is often used in pairs and installed in reverse. The inner and outer race rings can be installed separately, and the radial and axial clearances can be adjusted during installation and use; The large cone angle mainly bears axial and radial combined loads, mainly axial loads. It is generally not used alone to bear pure axial loads, but can be used to bear pure radial loads when configured as a pair (with the same end installed relative to each other).
definition
The ability of a single row tapered roller bearing to withstand axial loads depends on the contact angle, which is the angle of the outer raceway. The larger the angle, the greater the axial load capacity. The most commonly used type of tapered roller bearing is the single row tapered roller bearing. In the front wheel hub of the sedan, small-sized double row tapered roller bearings are used. Four row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.
Structural characteristics
The type code for tapered roller bearings is 30000, and tapered roller bearings are separable bearings. In general, especially within the size range mentioned in GB/T307.1-94 "Tolerances for Radial Bearings in Rolling Bearings", the outer ring and inner components of tapered roller bearings can be 100% interchangeable for universal use.
The angle of the outer ring and the diameter of the outer raceway have been standardized to match the external dimensions. No changes are allowed during design and manufacturing. To enable universal interchangeability between the outer and inner components of tapered roller bearings worldwide.
Conical roller bearings are mainly used to withstand combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearings, it has a higher load-bearing capacity and lower limit speed. Conical roller bearings can withstand axial loads in one direction and limit axial displacement of the shaft or housing in one direction.
