How To Install A Pillow Block Bearing

Installation of outer spherical bearing:

1. Before installing the bearing on the shaft, you must first unplug the fixing pin of the bearing jacket, and at the same time polish the surface of the journal smoothly, and apply oil to 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 bearing, and install the bearing into the bearing seat. Then put the assembled bearing on the shaft together with the bearing seat. Push to the desired location for installation.

3. Do not tighten the bolts that secure the bearing seat, and allow the bearing housing to rotate in the bearing seat. Also install the bearing and seat on the other end of the same shaft, rotate the shaft a few times, and let the bearing itself automatically find its position. Then tighten the bearing seat bolts.

4. Install eccentric sleeve. Put the eccentric sleeve on the eccentric step of the bearing inner sleeve first, and tighten it by hand in the direction of rotation of the shaft. Then insert the small iron rod into or against the counterbore on the eccentric sleeve. Hit the small iron rod with a hammer along the axis of rotation. Install the eccentric sleeve firmly, and finally tighten the hexagon socket screws on the eccentric sleeve.
