Description

Technical Field

[0002] When knurling the bearing ring, a knurling device is needed to perform knurling on the surface of the bearing ring. The existing knurling device is composed of a knurling roller, a mounting frame and a rotating shaft sleeve. When in use, the knurling roller is pressed on the outer diameter surface of the bearing ring workpiece. By rotating the bearing ring workpiece and allowing the knurling roller to exert a certain pressure on the bearing ring workpiece, the knurling is completed on the bearing ring workpiece.
