Special types Additional order codes (article number with "-Z") and, if required, plain text - Z 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 withMalways 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 without keyway. An exception to this rule is type BNN of series BIPEX-S to which tolerance H7 with keyway applies. The product code consists of a combination of digits and letters and is divided into three blocks linked by hyphens for better clarity. To order other types with keyway, the letter “-Z” must be appended to the product code. 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 article number are supplemented by information on the bore of the coupling hub parts and information on "Special Types".
