Selection method and precautions for agricultural machinery bearings: When selecting bearings, refer to the inner diameter of the bearing. The inner diameter of the bearing is represented by the first and second digits on the right end in the basic code. The inner diameter of bearings is divided into standard and non-standard inner diameters, and the difference is that non-standard inner diameters are not integers or multiples of 5. For the convenience of manual selection, the car bearing model query software Bearing World provides an example: for bearings with an inner diameter of less than 9mm, the actual size is represented by the advanced digit on the right end. For example, bearing number 18 has an inner diameter of 8 millimeters. Car bearing model query software The world of bearings will gradually become more fulfilling, and life will no longer be empty. Later on, face it, and next year it will bloom. ② The inner diameter of the bearing is expressed as a fixed number of 1017 millimeters. For example, bearing numbers 100, 201, 302, and 403 have inner diameter codes of 00, 01, 02, and 03 with two digits at the right end, and their inner diameters are represented by fixed numbers of 10, 12, 15, and 17 millimeters, respectively. Car bearing model query software Bearing World ③ The inner diameter of the bearing is 20480 millimeters (excluding 22, 28, and 32), represented by dividing the inner diameter size by 5. Car bearing model query software Bearing World ④ Bearings with an inner diameter of over 500 millimeters (22, 28, 32) are represented by fractions, denominators represent the inner diameter, and numerators represent the size of the bearings. Gradually, life will be very fulfilling, and there will be no more emptiness. Later, facing the future, the series, types, and structural forms will bloom next year. For example, bearing number 30031/560 has an inner diameter of 560 millimeters, and so on. Car bearing model query software Bearing World Bearing is a support component for various rotating shafts or movable parts of machinery, widely used in agricultural machinery such as agricultural vehicles, tractors, diesel engines, electric motors, threshers, etc.
