What are the functions of forklift needle roller bearings and what are the installation precautions?

Forklift needle roller bearings are a very important hardware component used on forklifts. They consist of four parts: outer ring, inner ring, rolling element and cage. They are mainly installed outside the king pin of the rear axle of the forklift. Its main functions are as follows:

1. Enables the forklift to flexibly rotate the rear tires at any time. By reducing the friction between the needle bearing and the steering kingpin, the rear axle of the forklift is less likely to wear.

2. Needle roller bearings are important accessories for the rear axle steering system of forklifts. Their presence plays an irreplaceable role in the normal operation and performance of forklifts.

When installing forklift needle roller bearings, you need to follow the following precautions:

1. Keep the forklift bearings and their surrounding environment clean, because even tiny dust invisible to the naked eye entering the forklift bearings may increase wear or cause vibration and noise.

2. During installation, no strong stamping is allowed, nor is it allowed to directly hit the forklift bearings with a hammer, nor is pressure transmitted through rolling elements.

3. Use appropriate and accurate installation tools and try to avoid using items such as cloth and short fibers.

4. Before installation, the bearings and bearing-related parts need to be cleaned, and the size and finishing of the related parts must be checked.

5. After installation is completed, an appropriate amount of lubricant (such as butter) should be supplied. The purpose of lubrication is to reduce internal friction and wear of the bearing, prevent burning and extend its service life. However, excessive lubricant will produce large resistance and affect the rotation speed, so special attention needs to be paid to the amount.

In addition, when handling forklift bearings directly by hand, you should fully wash off the sweat on your hands and apply high-quality mineral oil before operating. Especially in the rainy season and summer, you should pay more attention to rust prevention.

The installation and use of forklift needle roller bearings need to follow certain standards and precautions to ensure the normal operation and performance of the forklift. If you encounter problems during installation or use, it is recommended to seek help from professional technicians.
