How to protect the bearings in movable caster wheel?
Everyone knows that there is an important part in the movable caster, and the bearing is there. With the bearing, it is called the movable caster, otherwise it will not be much different from the fixed caster. Therefore, the bearing is a very critical step to form a movable caster. A good bearing is a powerful guarantee for improving the flexibility and rotation of the entire caster. So choosing a good bearing is very important.
Bearings are an important part of movable caster wheel. Its main function is to support the rotating body of the caster, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different frictional properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, its radial size, vibration and noise are larger and the price is higher.
When removing the caster bearings for inspection, first use photographic methods to make appearance records. In addition, confirm the amount of lubricant remaining and sample the lubricant before cleaning the caster bearings.
1. The cleaning of caster bearings is divided into coarse washing and fine washing, and a metal grid can be placed on the bottom of the container used.
2. When rough washing, use a brush or the like in the oil to remove grease or adhesions. At this time, if you turn the caster bearing in oil, be careful to damage the rolling surface due to foreign objects.
3. When fine washing, slowly turn the caster bearing in oil, which must be done carefully. The commonly used cleaning agent is neutral non-aqueous diesel or kerosene, and sometimes warm alkaline liquid is used as needed. No matter which cleaning agent is used, it must be filtered and kept clean. Immediately after cleaning, apply anti-rust oil or anti-rust grease to the caster bearings.
The lubrication methods of movable caster bearings are classified into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose a lubrication method suitable for the conditions of use and purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication simplifies the structure around the bearing, and compares the advantages and disadvantages of grease lubrication and oil lubrication. Pay special attention to the amount when lubricating. Whether it is oil lubrication or grease lubrication, too little lubrication will not fully affect the bearing life, too much will produce a large resistance and affect the speed. Therefore, when we add lubricating oil to the universal caster wheel or movable caster wheel, we must pay attention to the dosage, and do not use too much dosage to cause other adverse factors. At the same time, we must pay attention to the wear of the movable caster wheel on the bearings.
