The slewing bearing sometimes encounters rust during the use of the slewing bearing. The rusted slewing bearing will seriously affect the normal use of the equipment, and even cause damage to the equipment. So what is the reason for this situation, and what measures should we take to prevent it? Let me analyze it for you below.

The reason for the rust of the slewing bearing.

1. The quality is not up to standard

In the production process of slewing bearings, in order to obtain greater profits, some manufacturers use impure materials for production, which cannot meet the needs of the use of slewing bearings, so that the quality of the bearings is not up to standard, and the slewing bearings are accelerated to rust. The use of the slewing bearing itself is in a bad environment, which can easily lead to danger.

2. Use but not maintain

Slewing bearings are often used on large rotating machines. Due to the harsh environment of use, the slewing bearings cannot be cleaned in time during use and cannot be properly maintained, resulting in corrosion.

The slewing bearing is made of carbon structural steel, which will rust over time, which will affect the normal operation of the equipment and even cause some damage to the equipment. It is very important to prevent the slewing bearing from rusting

2. Preventive measures for rusting of slewing bearing

1. Immersion method

For some small bearings, it can be soaked in anti-rust grease, which can make the surface adhere to the upper layer of anti-rust grease, thereby reducing the chance of rusting.

2, brushing method

For some larger slewing bearings, the immersion method cannot be used, and it can be brushed. When brushing, pay attention to evenly smear on the surface of the slewing bearing, so as not to accumulate, and of course, be careful not to miss the coating, so as to prevent rust evenly.

3. Spray method

When the slewing bearing is used in some large rust-proof objects, it is not suitable to use the immersion method for oiling, but only spraying. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil. Generally, spraying is carried out in a clean air place with filtered compressed air with a pressure of about 0.7Mpa.

3. Maintenance method of rust of slewing bearing

1. Before using the slewing bearing, sufficient grease should be added to the product to reduce the damage of the rust-proof material on the surface of the slewing bearing due to wear.

2. During use, the sundries on the surface of the slewing bearing should be removed frequently, and the sealing strip of the slewing bearing should be checked for aging, cracking, damage or separation. If any of these situations occur, the sealing strip should be replaced in time to prevent the loss of sundries and grease in the raceway. After the replacement, the corresponding grease should be applied to avoid the rolling elements and the raceway from being caught or corroded.

3. When the slewing bearing is in use, avoid water entering the raceway to cause rust, and it is forbidden to wash it directly with water. During use, it is necessary to strictly prevent hard foreign objects from approaching or entering the meshing area, so as to avoid tooth injury or unnecessary trouble.

In addition to the quality problems, the rust of the slewing bearing is caused by improper use and maintenance to a certain extent. Quality problems can be avoided by choosing a good manufacturer, but the use and maintenance require users to pay more attention in peacetime. Regular maintenance can prolong the service life of the slewing bearing and reduce the risk and cost of use.
