How to protect the bearings in the moving caster?


Everybody knows that there is an important part in the foot wheel which is the bearing, which is called the moving caster, or it is not so different from the fixed casters; Therefore, the bearing is a very important step in making the casters. A good bearing is a strong guarantee for improving the flexibility and rotation of the whole caster. So it's very important to choose good bearings.

The bearing is an important part in the moving caster. Its main function is to support the caster rotation body, reduce the friction coefficient in its motion process, and guarantee its turning accuracy. The bearing can be divided into two categories: rolling bearing and sliding bearing according to the frictional quality of moving components. The rolling bearing has been standardized and serialized, but its radial dimension, vibration and noise are larger than that of sliding bearing, and the price is higher.

When the foot wheel bearings are removed for inspection, the appearance record should be done by photography and other methods. In addition, confirm the amount of residual lubricants and sample the lubricant, then clean the caster bearings.

1.The foot wheel bearings are cleaned and cleaned thoroughly, and can be placed on the bottom of the container.

2.Use a brush in oil to remove grease or adhesives during rough washing. If you rotate the casters in the oil, notice that the surface will be damaged by the foreign body.

3.In fine wash, slowly rotate the caster bearings in the oil and must be carried out carefully. The commonly used cleaning agent is neutral and non-aqueous diesel or kerosene, and it is sometimes used with warm lye when needed. No matter which cleaning agent is used, keep it clean. After cleaning, immediately coated with anti-rust oil or anti-rust grease on the caster bearings.

The lubrication method of movable caster bearings is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first, choose the lubrication method suitable for use condition and purpose. If only lubrication is considered, lubricate lubrication is advantageous. However, lipid lubrication has the advantages of simplifying the structure around the bearing and comparing the advantages and disadvantages of grease lubrication and oil lubrication. Special attention should be paid to the amount of lubrication, whether it is oil lubrication or grease lubrication, too little lubrication will not affect the bearing life, too much will cause great resistance and affect the speed. Therefore, when we add lubricating oil to the wheel or moving caster, we must pay attention to the amount of oil. Do not use too much quantity to cause other adverse factors. Also pay attention to the wear of the bearing when the moving caster is used.
