After the mechanization of industrial production, the use of machinery and equipment is more and more extensive, and its types are more and more. On this basis, bearing products have also been greatly developed, needle roller bearings are a more common type. Although needle roller bearings, like other workpieces, will become dirty over time, but the cleaning methods are different.

There are two main aspects. On the one hand, it is to make needle roller bearings in an ideal state of operation and prolong their service life; on the other hand, it is to give full play to the performance of needle roller bearings, so that mechanical equipment can operate normally.

Use brushes and other tools directly to remove grease or adhesives on the surface of needle roller bearings, but care should be taken not to damage the surface of needle roller bearings.

When cleaning, it is necessary to prepare neutral and non-aqueous diesel oil or kerosene as cleaning agent, of course, it can also use warm alkali liquor as required. Needle roller bearings are then slowly rotated in oil and carefully cleaned. In addition, after cleaning, the bearing surface should be coated with anti-rust oil or anti-rust grease, which has good anti-rust effect.

In a word, the cleaning of needle roller bearings is very exquisite. When operating, the needle roller bearings must be carried out strictly in accordance with the rules, in order to restore the clean surface on the premise of guaranteeing their performance.
