Technical points and precautions for outer spherical bearings:

disassembly

1. Use a Hex key to loosen the locking screw on the bearing eccentric sleeve, then use a small iron bar to insert 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.

install

Before installing the bearing on the shaft, the fixing pin of the bearing sleeve must be removed first, 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 the 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, and 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.
