Closed bearing: The seal or dust cover code in the code can be omitted; for example, "-2Z" and "-2RS" can be simply "-Z" and "-RS".
The symbol on the bearing; usually should be marked on the non-reference end face of the ferrule; but it can also be required according to the product pattern; marked on the ferrule reference end face, the outer ring outer cylindrical appearance, the shroud, the cage, the retaining ring, the sealing ring or the anti-proof Dust cover.

1 inner ring is not; outer ring is not; sealing ring or dust cover bearing code and manufacturer code (or trademark),
2 inner ring is not; outer ring bearing code and manufacturer code (or trademark); seal ring or dust cover scale series code, inner diameter code, seal ring or dust cover code,
3 inner ring bearing code and manufacturer code (or trademark); outer ring; seal ring or dust cover dust cover scale series code, inner diameter code, seal ring or dust cover code,
4 inner ring is not; outer ring bearing code and manufacturer code (or trademark); seal or dust cover is not,
5 inner ring bearing code and manufacturer code (or trademark); outer ring is not; seal or dust cover is not,

The bearing symbol can be mechanical, electro-erosive, laser, etc.; in special cases; chemical method can also be used. This chemical method is only suitable for small quantities of prototypes; or used to make up the bearing clearance group code and Pair and multi-bearing bearing related post code and symbol.
The bearing symbol should be complete and intact, the handwriting rules and clarity; the line thickness is uniform, the font standard and common, the word height of the symbol can be selected according to the following height (mm): 0. 5, 0. 7, 1. 2, 1. 5, 2, 2. 5, 3, 4, 5.
