What is the purpose of the taper roller auto bearing?

Taper roller auto bearing is a centripetal thrust structure, which can bear both axial and radial forces. Among them, the single row can only bear the axial force in one direction, and some types can bear the opposite axial force at the same time.

Why should taper roller auto bearings be installed in pairs?

Single-row taper roller auto bearings are generally installed in pairs, and can be installed back-to-back (DB) with the large end faces of the two outer rings facing each other, face-to-face with the small end faces of the two outer rings (DF), or a small outer ring. Tandem installation (DT) where the end face is connected to the large end face of the other outer ring. During the back-to-back installation of the bearing, the inner components on the outer side have to go through the process of installation, disassembly and re-installation. The matching between the inner diameter of the bearing and the shaft should be properly selected, and correct and reasonable tools should be used to facilitate installation and disassembly to ensure that the shaft, inner Rings, rollers and cages are not damaged.

Install the outer ring of the taper roller auto bearing into the bearing seat hole as shown in the figure below. Generally, there is a gap between the outer diameter of the bearing and the bearing seat hole, which can easily push the outer ring into the inner hole of the bearing.

What is the purpose of the taper roller auto bearing?

taper roller auto bearings: can bear radial and axial loads at the same time, double row taper roller auto bearings can bear bidirectional axial loads. Due to the sliding friction between the big end of the tapered roller and the inner ring rib, its limit speed is often lower than that of a cylindrical roller bearing of the same size. Hollow taper roller auto bearings can use oil to cool the rollers, so that the temperature rise is reduced, thereby increasing the allowable speed. However, the manufacturing process of this kind of bearing is complex, and the requirements for the lubrication system of the machine tool are also high. Generally, it is only used on the horizontal spindle with special requirements.

Where is the taper roller auto bearing used in the machine?

Tapered roller ball bearings can withstand large unidirectional axial loads, and the axial load capacity increases with the increase of the contact angle. The displacement and the limit speed are medium. When the radial and axial loads are relatively large, if the speed is not high, it can be selected. Such as the spindle of a lathe, the spindle of a milling machine, etc.

To meet these growing demands, Shandong Xuanye Precision Machinery Co., Ltd. has various taper roller auto bearings that can provide the increasing of products, and make them more effective, reliable, and consistent.
