How to protect the activity of castor bearing

Activity is known to all casters there is an important parts of bearing, a caster wheel bearing it is called 'activities, otherwise it will with fixed castor don't have much difference; So bearing is composed of caster is very crucial step, a good bearing is to improve the whole castor, rotational flexibility. So choose a good bearing is very important. Bearing is a kind of important activities castor components. Its main function is to support the castor, reduce the coefficient of friction in the process of movement, and guarantee its rotation accuracy. By the frictional properties of motion elements, bearing can be divided into two categories, the rolling bearing and sliding bearing. The rolling bearing is standardization, seriation, but compared with sliding bearing radial size of it, the vibration and noise is bigger, the price is higher also. Caster wheel bearings will be removed when checking, with photography method such as first and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then wash the caster wheel bearing. 1, the trundle bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. 2, coarse, washing oil using a brush to remove grease or adhesive. If at this time in oil rotating caster wheel bearings, pay attention to the rolling surface due to foreign bodies such as damage. 3, fine cleaning, slowly rotating caster wheel bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. After cleaning, immediately on the caster wheel bearing coating anticorrosive oil or antirust grease. Activity of caster wheel bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. To pay special attention to the dosage, lubricating oil or grease lubrication, too little quantity insufficient lubrication, affecting the service life of bearing too much will produce large amount of resistance, impact speed. So when we add lubricating oil to universal castor castor or activities must pay attention to the usage, please do not use too much the amount of lead to other adverse factors. Castor also must pay attention to activity when used in bearing wear and tear.
