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 unidirectional axial loads. When a bearing is subject to radial load, an axial force component will be generated, so when another bearing is needed that can withstand axial force in the opposite direction to balance it, 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 outer ring angle and outer raceway diameter have been standardized to match the external dimensions. No changes are allowed during design and manufacture. To enable universal interchangeability between the outer and inner components of tapered roller bearings worldwide. Tapered roller bearing is mainly used to support combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearings, it has higher load capacity and lower limit speed. Tapered roller bearings can support axial loads in one direction and limit axial displacement of the shaft or housing in one direction. A single-row tapered roller bearing has an outer ring, and its inner ring and a set of tapered rollers are enclosed by a basket-shaped cage to form an inner ring component. The outer ring can be separated from the inner component of the ring. According to ISO standard for the outer dimensions of tapered roller bearings, any standard model of tapered roller bearing outer ring or inner ring component must be able to achieve international interchangeability with the same outer ring model or inner ring component. The outer ring of the same model must comply with ISO492 (GB307) regulations for external dimensions and tolerances, and the cone angle and cone diameter of the inner ring components must also comply with relevant regulations for interchangeability. Typically, the cone angle of the outer raceway of a single-row tapered roller bearing is between 10° and 19°, which can simultaneously withstand the combined action of axial and radial loads. The greater the angle of the cone, the greater the ability to withstand axial loads. The bearing with a large cone angle with the suffix B, has a cone angle between 25° and 29°, and can withstand large axial loads. In addition, the clearance of single row tapered roller bearings can be adjusted during installation.
