Omission bearing basic code

  Earlier we said "bearing basic code", under normal circumstances bearing basic code is 5, which is a bearing type generations

No. (from left one), two dimension series code (second from left, three), two inner code (the last two).

However, some special cases, it will omit the code below to follow robin slowly learn it :)

Possible to use language to explain some chaos, I was sorting tables, will be made for everyone to download in PDF format, the first to leave a link here

Let me double row angular contact ball bearings, type code is "0", generally omitted, the basic code into four, and there are "3200" and

"3300," two series. The type code "3" at the backing bearings of the tapered roller bearing can not be omitted code, so the tapered roller shaft

By Order of the basic code is five, with such ease of double row angular contact ball bearing zones separated.
