Further, the width of the clamping groove is equal to that of the first bearing retainer ring.

Furthermore, the depth of the limiting groove is equal to one half of the height of the first bearing retainer ring.

Furthermore, the set screw is a socket head cap end set screw.

Furthermore, the set screw is coated with thread glue.

The utility model has the advantages that: the utility model relates to a bearing locking device, with bearing fixed mounting in the pivot, through setting up first bearing retaining ring, bearing pressure cover, second bearing retaining ring, screw holding screw, guarantee position relatively fixed between each part to the realization is to the locking of bearing, and the vibrations of having avoided the lathe during operation lead to the condition not hard up gradually between bearing and the pivot, thereby has effectively reduced equipment trouble or has formed the probability of potential safety hazard, has improved work efficiency.
