Product code key

The product code consists of a combination of digits and letters and is divided into three blocks linked by hyphens for better clarity. 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 product code are supplemented by information on the bore of the coupling hub parts and information on “Special types”.

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 dimension drawing.

“Special types” are linked to the 3rd block of the product code by appending the code “-Z”. Special order requirements are, for example, fine balancing G6.3 or the ATEX design of the coupling.

With this product code key, the couplings shown in the catalog can be completely specified. No further textual details are required, they should be avoided. Couplings in special variants are specified with the digit 9 in the 4th place in the product code (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 appending “-Z Y99”, plain text information can be included. The plain text information can then clearly specify the features of the special coupling.
