Additional order codes for bore specifications
(without “-Z” specification)

Order codes have been specified for the bore specifications.
Finished bores can be ordered by specifying code digit 9 in the 11th and/or 12th position of the product code and additionally the supplementary order code for ∅ D1 and/or ∅ D2 from the following table.

H7 is selected for all coupling series where no bore tolerance is specified.

Bore diameters deviating from the table values must be ordered by stating the code number 9 in the 11th and/or 12th position of the product code, adding “-Z” to the product code and the order code L9Y with plain text for the left-hand hub and order code M9Y with plain text for the right-hand hub.
