Bearing's general agent: bearing show you uncover the secret of the sealing material source: bearing | last updated: - 2020 06 - 27 bearing website general agent: bearing show you uncover the secret of the sealing material deep groove ball bearings used in sealing material of basic requirements: 1. Deep groove ball bearing is wear-resisting, not metal corrosion; 2. Good oxygen resistance and aging resistance, durable; 3. Bearing resistance to high temperature and low temperature. It won't synthesis and softening under high temperature, not hardening in low temperature; 4. Deep groove ball bearing and working medium compatibility, no swelling, synthesis, the phenomenon such as hardening. 5. Flexible and appropriate hardness, less compaction permanent deformation; Deep groove ball bearing materials of metallurgical quality were the main factors influencing the 6209 premature failure of the bearing. With the progress of metallurgical technology ( For example, the bearing steel vacuum degassing, etc. ) , to improve the quality of raw materials. The proportion of raw materials quality factors in the bearing failure analysis has significantly decreased, but is still one of the main factors influencing the bearing failure. The correct selection of materials is still bearing failure analysis of factors must be considered. Bearing is a common type of rolling bearing. By the basic bearing outer ring, inner ring, a set of steel ball and a set of cage. Bearing has two types: single and double column. Deep groove ball structure is divided into two kinds: seal and open. Open means no bearing seal structure. Seal. Dustproof cover gasket material composed of steel plate stamping, is only used to prevent dust from entering the bearing raceway simply. Oil type is contact oil seal, can effectively prevent the bearing of the oil spill. Single bearing code is 6, double row bearing code is 4. Its structure is simple and easy to use, is the most commonly used and applied most widely bearing. Bearing is mainly used to bear radial load, but also is often used to carry the combination of radial and axial load. Especially when the speed of the machinery and equipment are high, not suitable for the use of thrust bearing. Can be used to carry two-way pure axial load, no maintenance during the work.
