How to maintain the bearings of the crusher?

The bearings of the crusher are key parts that support the operation of the rotor. In the hammer crusher, the main shaft bearing uses a cylindrical roller rolling bearing, which is a mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction.

The method of maintaining the bearings of the crusher is as follows:

Keep the bearings and their surroundings clean to prevent contaminants and dust from entering the bearings and avoiding corrosion and damage.

During operation, you need to be careful to avoid strong impacts on the bearings and prevent problems such as scratches, indentations, and fractures on the bearings.

Use appropriate tools for operation to avoid damage to the bearings caused by incorrect operations.

Pay attention to the anti-rust of the bearings and avoid using the bearings in humid places to prevent rust. At the same time, in order to prevent sweat from staining the bearings and causing damage, gloves should be worn during operation.

Choose and use the correct type of grease, such as No. 3 lithium-based grease (composed of lithium soap and lubricating oil, without ingredients harmful to the human body). The filling amount of grease is generally 1/2-2/ of the bearing cavity space. 3. When the grease becomes dirty, dry or aged, it should be replaced in time. Under normal circumstances, bearings need to be re-greased after 3,000 hours of use.

During maintenance, the bearings should be carefully inspected, such as cleaning, lubricating, and checking their coordination. Those that do not meet the requirements should be replaced in time.

In short, maintaining the bearings of the crusher is an important measure to ensure its normal operation. It needs to be kept clean, used and maintained rationally to extend the service life of the crusher.
