Article number code
■
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. The coupling series, the type and the size are encoded in
blocks 1 and 2. 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
dimension drawing.
The order code without the letter “-Z” refers to tolerance H7 with-
out keyway. An exception to this rule is type BNN of series
BIPEX-S to which tolerance H7 with keyway applies.
To order other types with keyway, the letter “-Z” must be
appended to the article number.
L40 / M40 = Keyway according to DIN 6885, keyway width JS9
L41 / M41 = Keyway according to DIN 6885, keyway width P9
