What are the precautions for disassembly and installation of spherical bearings with seats?

Summary:

Disassembly steps and precautions:
1. Use an Allen wrench to loosen the locking screw on the bearing eccentric sleeve, and then use a small iron rod to insert the counterbore on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the rotation direction of the shaft.
2. Loosen the bolts fixing the bearing seat. Remove the bearing together with the bearing seat from the shaft. Note before removing the bearing housing at one end of the shaft. The bearing seat bolts at the other end of the shaft should be loosened to prevent the bearings at both ends from being stiff and damaged.
Installation steps and precautions:
1. Before installing the bearing on the shaft, you must first remove the fixing pin of the bearing jacket, at the same time polish the surface of the journal to be smooth and clean, and apply oil to the journal to prevent rust and lubrication (allowing the bearing to rotate slightly on the shaft).
2. Apply lubricating oil to the mating surfaces of the bearing housing and bearing, and install the bearing into the bearing housing. Then put the assembled bearing on the shaft together with the bearing seat. Push to the desired location to install.
3. Don't tighten the bolts to fix the bearing housing first, let the bearing jacket rotate in the bearing housing. Also install the other end bearing and seat on the same shaft, turn the shaft a few times, and let the bearing itself find the correct position automatically. Then tighten the bearing seat bolts.
4. Install eccentric sleeve. First put the eccentric sleeve on the eccentric step of the bearing inner sleeve, and tighten it by hand along the rotation direction of the shaft. Then insert or hold the small iron rod into the countersink hole. Use a hammer to strike the iron rod in the direction of rotation of the shaft. Install the eccentric sleeve firmly, and finally tighten the hexagon socket screws on the eccentric sleeve.
