Sb 202 bearing is actually a variant of the deep groove ball bearing

The sb 202 bearing is actually a variant of the deep groove ball bearing, which is characterized by that the outer diameter surface of its outer ring is spherical, and it can be fitted into the corresponding concave sphere of the bearing seat to play the role of aligning.
The installation of sb 202 bearing:
1. Before installing the sb 202 bearing on the shaft, it is necessary to remove the fixing pin of the bearing jacket, at the same time, polish the surface of the journal and grease the journal for rust prevention and lubrication (allowing the bearing to rotate slightly on the shaft).

2. Apply lubricating oil to the matching surface of the bearing seat and the bearing, and load the sb 202 bearing into the bearing seat.Then the assembled bearing is sheathed on the shaft together with the bearing seat.Push to the desired location for installation.
3. Do not tighten the bolts that fix the bearing seat, and let the sb 202 bearing jacket rotate in the bearing seat.The other end of the sb 202 bearing and seat on the same shaft are also installed. Rotate the shaft for several turns and let the bearing itself automatically find the right position.

4. Install eccentric sleeves.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 the small iron bar is inserted or pressed against the countersunk hole on the eccentric sleeve.Hit the small iron bar with the hand hammer in the direction of rotation of the shaft.Make the eccentric sleeve firmly installed, and finally lock the inner hexagon screw on the eccentric sleeve.
