In a humid environment for a long time, the slewing bearing is prone to rust, which will reduce the mechanical efficiency. This article comprehensively introduces how to prevent rust on slewing bearings.

In order to ensure the high quality of the slewing bearing, this article will introduce how to rust-proof the slewing bearing for customers and friends.

As a kind of bearing field, slewing bearing is called "the joint of the machine", and it is mainly used in construction machinery, construction machinery, lifting and handling equipment, manufacturing industry, ship port, power generation equipment and so on.

Anti-rust method of non-installed slewing bearing

1. When the slewing bearing leaves the factory, the raceway has been filled with grease, and the surface has been coated with anti-rust oil or spray paint. The packaging of the slewing bearing can be packaged in a single package or in a full turn package according to customer needs.

2. If it is not installed and used, oiling and maintenance of the non-painted surface should be carried out once every 6 months to prevent rust. In the southern region, oiling and maintenance of the non-painted surface should be carried out once every 3 months. The slewing bearing raceway should be guaranteed to be lubricated and maintained once a year to replace the grease.

During maintenance, rotate the slewing bearing to check whether the operation is flexible. After all maintenance, the original state of the slewing bearing should be restored and packaged with film.

3. The slewing bearing should be stored in a non-corrosive medium, dry and flat room, and should not be soaked or drenched in water.

4. Place the slewing bearing in a stable place, avoid vertical or oblique placement. When laying flat (except for full-turn packaging), at least 3-5 spacers should be evenly distributed in the circumferential direction between each slewing bearing, and the positions of the upper and lower blocks should be the same on the circumference.

The slewing bearing that has been idle for many years (especially where there is a lot of rain) should be checked when it is put into use. Please contact the Niulix sales representative for the inspection items.

Anti-rust method of installed slewing bearing

1. Try to keep away from the corrosion of corrosive substances on the product;

2. Regularly inspect the surface of the product. If you find that the paint surface or zinc surface that cannot be handled by yourself is damaged, you should contact the manufacturer for assistance in time;

3. Keep the storage environment dry;

4. Try not to touch it with your hands when not in use to avoid corrosion to the support.
