Tapered roller bearing

Tapered roller bearings refer to radial thrust rolling bearings whose rolling elements are tapered rollers.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. They are often used in pairs and installed in reverse. The inner and outer races can be installed separately. The radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the combined axial and radial loads, which are mainly axial loads. Generally, they are not used to bear pure axial loads alone. When configured in pairs (ends with the same name are installed oppositely), they can be used to bear pure radial loads.

The type code of tapered roller bearings is 30000, and tapered roller bearings are separate bearings.Under normal circumstances, especially within the size range involved in GB/T307.1-94 "Rolling Bearings Radial Bearing Tolerances", the outer ring and inner components of tapered roller bearings are 100% interchangeable.
