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".
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.
"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.
