The outer spherical bearing fixes the inner ring of the bearing with the shaft through an eccentric sleeve, and the hexagon socket screw on the eccentric sleeve acts as a fastening.

1)Disassembly

a)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 direction of rotation of the shaft.

b)Loosen the bolts that secure the bearing seat. Remove the bearing together with the bearing seat from the shaft. Note that before removing the bearing seat at one end of the shaft. The bearing seat bolt at the other end of the shaft should be loosened to avoid damage to the bearings at both ends.

 

2) installation

a)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).

b)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 to the desired location for installation.

c)Do not tighten the bolts that fix the bearing seat, but 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.

d)Install eccentric sleeve. Put the eccentric sleeve on the eccentric step of the FAG 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. Knock the small iron rod along the axis of rotation with a hand hammer. Install the eccentric sleeve firmly, and finally tighten the hexagon socket screw on the eccentric sleeve.
