Analysis of the specifications of the ball bearing, properties and classification

Analysis of the specifications of the ball bearing, properties, and classification of bearing damage is the main reason of roller bearing ring guard card injuries, lack of lubricant, not suitable for, for the defect of oil discharge structure, foreign invasion, bearing installation error, the deflection of the shaft is too big, therefore, entrance bearing damage, near use premise, bearing, mechanical structure is the most or a combination of bearing damage status and other reasons, can prevent the similar accident happen again. Micro and small ball bearing tiny ball bearing is composed of outer ring, inner ring, rolling, rolling retainer, seal ( Dust cover) And spring coil of machining parts. Less than 30 mm outside diameter is called the micro and small ball bearing, is to ensure that the shaft of the rotating equipment with high precision requirements stable operation of the bearing parts and assembly in precision parts. Large and medium-sized ball bearing ( The plane related parts) Applied in aviation supplies of ball bearing, relative to the average small ball bearings, ball bearings and the material is different, the number of pay more attention to the durability on the structure. The performance of the bearing: 1) Low noise; 2) High speed; 3) High precision; 4) Long life. Ball bearing specifications
