Installation and Removal for Pillow Block Bearings Introduction:

Installation and removal for pillow block bearings has bothered many users.
Pillow block bearing is a kind of bearing with a spherical outer surface of the outer ring, and it has covers on both sides.
The following describes its installation and removal methods:

Installation Method:

① When installing the bearing on the shaft, first of all, you must remove the fixing pin of the bearing jacket. At the same time, polish the journal surface smoothly and cleanly, and apply oil on the journal to avoid rust and lubrication. At this time, we allow the bearing to rotate slightly on the shaft.

② Coat the mating surface of the bearing and the bearing seat with lubricating oil, and then install the bearing into the bearing seat. Then put the assembled bearing on the shaft together with the bearing seat and push to the desired location for installation.

③ In order to let the bearing housing rotate freely in the bearing seat, don’t tighten the bolts which fix the bearing seat.  Similarly, when the other end bearing and bearing seat on the same shaft are installed, the shaft should be rotated a few times first, in order to make the bearing itself self-aligned. Finally, tighten the bearing seat bolts.

Removal Method:

① Loosen the locking screw on the eccentric sleeve of the bearing with an Allen key. 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 which fixing the bearing seat. Remove the bearing together with the bearing housing from the shaft. Note: Before removing the bearing housing at one end of the shaft. The bearing housing bolts on the other end of the shaft should be loosened in order to prevent the bearings at both ends from being energized each other, which will result in damage.
