Taper roller bearing refers to radial thrust type rolling bearing whose rolling body is a taper roller. There are two types of small and large cone angles. Small cone Angle mainly bear radial direction load primarily radial and axial loads, often used in pairs, reverse installation, inner and outer race can be installed separately, in installation using radial and axial clearance can be adjusted; Big cone Angle mainly bear axial load primarily of axial and radial load, is generally not used to bear alone the pure axial load, as to the configuration (end with the same relative installation) can be used to carry pure radial load.
Tapered roller bearing is a kind of separated bearing with tapered raceway on the inner and outer ring of the bearing. This kind of bearing can be divided into single row, double row and four row cone roller bearing according to the number of loaded roller. Single row taper roller bearings can withstand radial load and single directional axial load. When the bearing is subjected to radial load, an axial component is generated, so when another bearing is required to withstand the axial force in the opposite direction to balance.
The conical roller bearing mainly bears the combined radial and axial loads. Bearing capacity depends on the raceway Angle of the outer ring. This kind of bearing is a separate type bearing, which can be divided into single row, double row and four row taper roller bearing according to the number of rolling bodies in the bearing. The clearance of single row taper roller bearing needs to be adjusted during installation. The clearance of double row and four row taper roller bearings has been given according to the requirements of the user when the products are produced, no user adjustment is required.
Taper roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
