Single row tapered roller bearing top
When machining the outer circumference of a long pipe fitting, if the inner hole is large, the ordinary tip cannot be used. The method of inserting a plug can be used to process a single-piece pipe. If the single-row tapered roller bearing tip is used, the above problems can be solved. The following are introduced: (1) The choice of bearing first measures the inner diameter of the pipe, and then selects the single-row tapered roller bearing according to the inner diameter of the pipe, preferably the inner diameter of the pipe. Less than the median diameter of the inner ring of the bearing, and smaller than the inner ring of the bearing
