The outer spherical bearing is actually a variant of the deep groove ball bearing, characterized by its outer diameter surface being spherical, which can be matched into the corresponding concave spherical surface of the bearing seat for centering. When encountering the need to disassemble or install outer spherical bearings, many users do not know how to do so. Below, we will introduce the installation and disassembly methods.

1、 Installation of outer spherical bearings

1. Before installing the bearing on the shaft, the fixing pin of the bearing sleeve must be removed, and the surface of the journal must be polished smooth and clean. Oil should be applied to prevent rust and lubricate the journal (allowing the bearing to rotate slightly on the shaft).

2. Apply lubricating oil to the mating surface between the bearing seat and the bearing, and install the bearing into the bearing seat. Then place the assembled bearing and bearing seat together on the shaft and push them to the desired position for installation. 3. Do not tighten the bolts that fix the bearing seat yet, so that the bearing sleeve can rotate inside the bearing seat. Install the other end bearing and seat on the same shaft, rotate the shaft a few revolutions, and let the bearing itself automatically align. Tighten the bearing seat bolts again.

4. Install eccentric sleeve. First, place the eccentric sleeve on the eccentric step of the bearing inner sleeve and tighten it by hand in the direction of rotation of the shaft. Then, insert or counter the small iron rod into the counterbore on the eccentric sleeve. Use a hammer to strike the small iron rod in the direction of rotation of the shaft to firmly install the eccentric sleeve. Finally, lock the inner hexagon screw on the eccentric sleeve. 2、 Disassembly

1. First, loosen the locking screw on the bearing eccentric sleeve with a Hex key, then insert a small iron bar into the counterbore on the top cover eccentric sleeve, and loosen the eccentric sleeve against the rotation direction of the shaft.

2. Loosen the bolts that secure the bearing seat. Remove the bearing along with the bearing seat from the shaft. Before disassembling the bearing seat at one end of the shaft, loosen the bolts on the bearing seat at the other end of the shaft to avoid damage to the bearings at both ends due to mutual tension.

Before installing or disassembling bearings, it is necessary to master some basic operating knowledge to avoid losses caused by blind operation.
