Installation And Disassembly Of Pillow Block Bearing And Precautions

Installation steps and precautions for outer spherical surface with seat:

1. Before installing the bearing on the shaft, the fixing pin of the bearing casing must be pulled out first, and at the same time, the surface of the journal is polished smooth and clean, and oiled on the journal to prevent rust and lubricate (allow the bearing to rotate slightly on the shaft).

2. Apply lubricating oil on the mating surface of the bearing seat and the bearing, and install the bearing into the bearing seat. Then put the assembled bearing on the shaft together with the bearing seat. Push it to the desired position for installation.

3. Do not tighten the bolts for fixing the bearing seat first, and make the bearing jacket rotate in the bearing seat. Also install the bearing and seat at the other end of the same shaft, turn the shaft a few times, and let the bearing itself find its position automatically. Then tighten the bearing seat bolts.

4. Install the eccentric sleeve. First put the eccentric sleeve on the eccentric step of the inner sleeve of the bearing, and tighten it by hand along the rotation direction of the shaft. Then insert or withstand the counterbore on the eccentric sleeve with the small iron rod. Hit the small iron rod with a hand hammer in the direction of rotation of the shaft. Make the eccentric sleeve installed firmly, and finally tighten the hexagon socket screws on the eccentric sleeve.

Steps and precautions for disassembling the outer spherical surface with seat:

1. First loosen the locking screw on the eccentric sleeve of the bearing with an inner hexagonal wrench, then insert a small iron rod into 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 with the housing from the shaft. Be careful 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 avoid damage to the bearings at both ends.
