NTN Tapered roller bearing

NTN tapered roller bearing refers to radial thrust rolling bearing with tapered roller as rolling element. There are small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial load dominated by radial load. It is often used in double and installed in reverse. The inner and outer seat rings 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 load dominated by axial load. Generally, it is not used alone to bear the pure axial load. It can be used to bear the pure radial load when it is used as a pair configuration (opposite installation at the same end)

definition
the ability of single row tapered roller bearings to bear axial load depends on the contact angle, that is, the outer race raceway angle. The greater the angle, the greater the axial load capacity. Single row tapered roller bearings are the most widely used tapered roller bearings. A small size double row tapered roller bearing is used in the front wheel hub of a car. Four row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills

structural features
the type code of tapered roller bearing is 30000, and the tapered roller bearing is a separate bearing. In general, especially in GB / T307 The outer ring and inner assembly of tapered roller bearing within the size range involved in 1-94 tolerances for radial bearings of rolling bearings can be used interchangeably
the angle of the outer ring and the diameter dimension of the outer raceway are the same as the overall dimension and are standardized. It is not allowed to change during design and manufacturing. So that the outer ring and inner components of tapered roller bearing can be interchanged all over the world
tapered roller bearings are mainly used to bear combined radial and axial loads dominated by radial loads. Compared with angular contact ball bearing, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or shell in one direction
