Here is a general overview of the tolerances applied by Weerg according to European standards.
The regulation applied by Weerg is 2768-1 fine (f) and medium (m) classes.
This regulation applies to various features, including:
external dimensions
internal dimensions
stair dimensions, diameters, radii, distances, outer radii
chamfer heights for edges.
When using these tolerances, it is necessary to mark the tolerance class after ISO 2768 (e.g. ISO 2768- m for medium class) on or near the nameplate.
Here are the reference tables:

Note that in the event of any discrepancies between the dimension stated in our PDF document and the general tolerance set, the dimension specifically stated in the PDF document will take priority. This ensures that the most precise and detailed measurements in the PDF document are considered binding for our production.
Weerg offers a wide range of tolerances applicable to holes and shafts. Please refer to the dedicated page for more information.
