When disassembling the double row spherical roller bearing for inspection, first record the appearance using photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearings.

a. The cleaning of double row spherical roller bearings is divided into rough cleaning and fine cleaning, and a metal grid can be placed at the bottom of the container used.

b. During rough cleaning, use a brush in oil to remove grease or sticky matter. At this time, if the bearing is rotated in oil, be aware that the rolling surface may be damaged by foreign matter, etc.

c. When fine cleaning, slowly rotate the double-row spherical roller bearing in the oil and do it carefully. The commonly used cleaning agents are neutral non-aqueous diesel or kerosene, and warm alkali solution is sometimes used as needed. No matter which cleaning agent you use, filter it frequently to keep it clean. After cleaning, immediately apply anti-rust oil or anti-rust grease to the double-row spherical roller bearing.
