1. Three kinds of self-aligning roller bearings are suitable for working under heavy load or vibration load, but they can not bear pure axial load. The outer raceway of this kind of bearing is spherical, so its alignment performance is good and it can compensate coaxiality error.

　　

　　2. In the new design of main engine for three kinds of self-aligning roller bearings, symmetrical self-aligning roller bearings are seldom used. After comprehensive improvement of internal structure and parameter optimization, compared with the self-aligning roller bearings manufactured in the early stage, they can withstand more axial loads. The operating temperature of the bearings is lower, so they can meet the requirements of higher rotational speed.

　　

　　3. Three types of self-aligning roller bearings can also provide self-aligning roller bearings with taper bores for customers to load and unload and replace bearings. They are widely used in metallurgy, petroleum, papermaking, cement and other industries.

　　

　　This is the end of the introduction of the three types of bearings, hoping to bring you some help.
