Examples of agricultural machinery bearing

1. The agricultural  bearing  inner diameter of 9 mm below use the right end of the first digit  actual size. For example, bearing No. 18, its inner diameter 8 mm.
2. The bearing inner diameter of 10 - 17 mm  represented by fixed number. For example, bearing No. 100, 201, 302, 403 respectively, the inner diameter of the right end of the code of two digits is 00, 01, 02, 03, 10, 12 respectively for the inner diameter, 17 mm, 15 fixed digital representation.
3. The rotary bearing inner diameter of 20 - 480 mm (22, 28, 32, except) to diameter size in addition to 5 the number of representation.
4. The crossed roller bearings inner diameter over 500 mm (22, 28, 32) is expressed as a fraction, the denominator said diameter, molecular said bearing size series, type and structure form. For example, 30031/560 bearing, the inner diameter of 560 mm,and so on.
