FLENDER Standard Couplings Coupling Preselection and Options © Siemens AG 2015 Article number key ■ Overview The article number consists of a combination of digits and letters and is divided into three blocks linked by hyphens for better clar- ity. In blocks 1 and 2 the coupling series, the type and the size are encoded. Block 3 contains information applying only to the coupling specified in blocks 1 and 2. The three blocks of the ar- ticle number are supplemented by information on the bore of the coupling hub parts and information on "Special types". "Special types" are linked to the 3rd block of the article number by appending the code "-Z".
Special order requirements are, for example, fine balancing G6.3 or the ATEX design of the cou- pling. With this article number key, the couplings shown in the catalog can be completely specified. No further textual details are re- quired, they should be avoided. Couplings in special variants are specified with the digit 9 in the 4th place in the article number (block 1) and additionally with 00-0AA0 in positions 11 to 16. Series, type and size should, as far as possible, be specified in accordance with the coding for the standard coupling. By ap- pending "-Z Y99", plain text information can be included.
The plain text information can then clearly specify the features of the special coupling. 3 The bore details with the code letter L always refer to the bore diameter D1 of the hub part shown on the left on the dimension drawing. The order code beginning with M always refers to the bore diameter D2 of the hub part shown on the right on the di- mension drawing. 3/8 Siemens MD 10.1 · 2015 Structure of the article number Position 1 2 3 4 5 6 7 - 8 9 10 11 12 - 13 14 15 16 FLENDER Standard Couplings Positions 1 to 3 digit, letter, letter Type 2 L C Position 4 digit Coupling design 0 ...
