Structure
YF-ST high quality carbon steel as the base, through the rational design of oil, coated with grease during assembly makes it a long time at work when needed enough storage oil and can be evenly distributed in the surface of the bearing and shaft on, so as to achieve a long life the purpose of reducing the frequency of refueling; the same time because of the special oil system can work intrusion into the dust and other foreign matter bearing, thus reducing the maximum use of the bearing during the impact. YF-ST Another particularity is the bearing surface of the work handled through a special process, so that the surface covered by a layer of special solid lubricant, this layer of a special lubricant in the initial action quickly shifted to grinding the surface of the shaft, thereby rapidly reducing the coefficient of starting friction, improve wear resistance of the bearing.
