Abstract: A bearing assembly has a bottom base, a lower plate, an upper plate and a top base. At least one first locking device is configured between the lower plate and the bottom base. At least one second locking device is configured between the upper plate and the top base. Accordingly, the bearing assembly can bear a large shear stress by means of the locking devices. Enlarging the diameter of the bolts for attaching the lower plate to the bottom base or for attaching the upper plate to the top plate is not needed. The bearing assembly can bear a larger shear stress with fewer bolts than a conventional bearing assembly. The cost to manufacture the bearing assembly with a high structural strength is reduced.
