Matched tapered roller bearings are generally used to bear higher radial loads and bidirectional axial loads, or the shaft system needs to be axially positioned in two directions and needs to achieve a given preload or clearance. General, there are three matching configurations: face-to-face, back-to-back, and tandem. After matched bearings, the original axial clearance of the bearing has been fixed, and the user can directly install and use without adjusting the spacer, thus simplifying the installation procedure and avoiding installation errors, so it is widely used in various types of rolling mills, petroleum machinery, and medium and large transmissions.
 
Tapered roller bearings are mainly used to bear combined radial and axial loads based on radial loads. Generally, it is not suitable to bear axial loads alone. This type of bearing is designed so that the vertices of each conical surface of the inner ring raceway surface, the outer ring raceway surface, and the roller rolling surface intersect at a point on the centerline of the bearing. In addition to the metric series products, there are also a variety of imperial series products. Suitable for bearing heavy load and shock load. In addition to single-row bearings, tapered roller bearings include double row bearings, matched double bearings, and four-row bearings. The tapered roller bearing cage generally uses a stamped cage.
