Instantly know precision taper roller bearings size range and tolerance.

A precision taper roller bearings is a radial thrust type rolling bearing in which the rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the radial and axial combined loads mainly based on radial load. It is often used in double and reverse installation. 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 is mainly subjected to axial and radial combined loads mainly based on axial loads. Generally, it is not used alone to withstand pure axial loads. When paired configuration (relatively installed at the same name), it can be used to withstand pure radial loads.
