30307 Tapered roller bearings

30307 Tapered roller bearing refers to the radial thrust type rolling bearing whose rolling body is a tapered roller. There are small cone angles and large cone angles. The small cone Angle mainly bears the radial and axial combined loads mainly based on radial loads, often used in double, reverse installation, the inner and outer seat rings can be installed respectively, and the radial and axial clearance can be adjusted during installation and use. The large cone Angle mainly bears axial and radial combined loads based on axial loads, and is generally not used to bear pure axial loads alone, but can be used to bear pure radial loads when it is configured (the same name is relatively installed)
