After the realization of mechanization of industrial production, the use of machinery and equipment is more and more extensive, and its types are also more and more. On this basis, bearing products have also been developed to a great extent, and needle roller bearings belong to a more common kind. Although needle roller bearings, like other workpiece, will become dirty for a long time, but the cleaning method is different.

 

 

1. The purpose of cleaning and maintaining needle roller bearings

 

 

 

There are two main aspects, on the one hand, in order to make the needle roller bearing in the ideal running state, prolong its service life; On the other hand, in order to give full play to the performance of needle roller bearings, so that mechanical equipment can operate normally.

 

 

 

2. Rough cleaning of needle roller bearings

 

 

 

Use brushes and other tools to remove grease or adhesions on the surface of needle roller bearings directly, but pay attention not to damage the surface of needle roller bearings.

 

 

 

3, needle roller bearing cleaning method of fine cleaning

 

 

 

When cleaning, it is necessary to prepare neutral non-aqueous diesel or kerosene as cleaning agent, of course, you can also use warm lye according to the need. Then the needle roller bearing is slowly rotated in the oil and carefully cleaned. In addition, after the completion of cleaning, the bearing surface should be coated with anti-rust oil or anti-rust grease, which has a good anti-rust effect.

 

 

 

In a word, the cleaning of needle roller bearings is very particular, and the operation must be carried out in strict accordance with the rules, in order to ensure its performance on the premise of restoring a clean surface.
