Tapered roller bearings are separable bearings, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in one direction. When the bearing is subjected to radial load, an axial component force will be generated, so when another bearing that can withstand axial force in the opposite direction is required to balance.

Tapered roller bearings are separable bearings, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in one direction. When the bearing is subjected to radial load, an axial component force will be generated, so when another bearing that can withstand axial force in the opposite direction is required to balance. Tapered roller bearings refer to radial thrust rolling bearings whose rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small taper angle mainly bears the combined radial and axial loads mainly based on the radial load, and is often used in double, reversely installed, the inner and outer races can be installed separately, and the radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the combined axial and radial loads mainly based on the axial load. Generally, it is not used to bear the pure axial load alone, but can be used to bear the pure radial load when it is configured in pairs (the ends with the same name are installed opposite to each other). Tapered roller bearings mainly bear the combined radial and axial loads mainly in the radial direction. The bearing capacity depends on the raceway angle of the outer ring, and the larger the angle, the greater the bearing capacity. This type of bearing is a separable bearing, which is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearance of double-row and four-row tapered roller bearings has been given according to the user's requirements when the product leaves the factory, and does not need to be adjusted by the user.

Tapered roller bearings mainly bear the combined radial and axial loads mainly in the radial direction. The bearing capacity depends on the raceway angle of the outer ring, and the larger the angle, the greater the bearing capacity. This type of bearing is a separable bearing, which is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearance of double-row and four-row tapered roller bearings has been given according to the user's requirements when the product leaves the factory, and does not need to be adjusted by the user.

Tapered roller bearings refer to radial thrust rolling bearings whose rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small taper angle mainly bears the combined radial and axial loads mainly based on the radial load, and is often used in double, reversely installed, the inner and outer races can be installed separately, and the radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the combined axial and radial loads mainly based on the axial load. Generally, it is not used to bear the pure axial load alone, but can be used to bear the pure radial load when it is configured in pairs (the ends with the same name are installed opposite to each other).
