The parts might have a slight clearance or a slight interference, used for accurate location where a light push is needed. Interference Fit (Press Fit):

Understanding DIN 7161: The Foundation of ISO Limits and Fits

Example Matrix: Hole Class H7 (Values represented in micrometers, µm) ---------------------------------------------------------------------- Above Size (mm) | Up to Size (mm) | Lower (EI) | Upper (ES) ---------------------------------------------------------------------- 1 | 3 | 0 | +10 3 | 6 | 0 | +12 6 | 10 | 0 | +15 10 | 18 | 0 | +18 For a drawing specifying a internal bore: The nominal size falls into the 10 mm to 18 mm range. The lower limit deviation is . The physical minimum hole limit is exactly . The upper limit deviation is . The physical maximum hole limit is exactly . The allowed margin for manufacturing error is exactly Resolving Industrial Nomenclature Overlaps din 7161 pdf

In November 1990, DIN 7161 was officially replaced by . This transition marked a significant upgrade: the new standard incorporated the latest ISO revisions, additional tolerance grades, and clearer definitions.

is a German Institute for Standardization (Deutsches Institut für Normung) standard that defines the ISO deviations for holes (internal measurements) for nominal sizes ranging from The parts might have a slight clearance or

Bearings pressed into housings, gear wheels on shafts. Common ISO designations: H7/p6 or H7/r6. 3. Transition Fits

hole, you would consult the table for the "Over 30 to 50" size range and look for the row corresponding to ' ' and column ' '. The table provides the deviation that, when applied to , gives the allowable minimum and maximum size. Where to Find DIN 7161 PDF Documents The physical minimum hole limit is exactly

is a German standard (Deutsches Institut für Normung) that specifies general tolerances for linear and angular dimensions. It is primarily used in conjunction with DIN 7168 , which deals with the general tolerances for form and position.

(Geometrical product specifications - ISO code system for tolerances on linear sizes) for the current international standard on fits and tolerances. However, DIN 7161 remains a frequent "legacy" reference in older technical drawings and European maintenance manuals. Würth Industry Vietnam Why You Might Still Need the PDF Even though it’s an older standard, the DIN 7161 PDF remains popular for: Maintenance & Repair

“The table presents the technical specifications of ISO-DIN 7160/7161 tolerances... indicating the maximum and minimum allowable values for each group.” Scribd

Look down the left column for the range containing 30mm. You will see a row defined as Over 18 to 30 or Over 30 to 50 . (Note: Per standard rules, 30mm falls into the 18 to 30mm step). Locate the Column: Find the column labeled H7 . Read the Deviations: The table will list two values: Upper limit: +21 Lower limit: 0 Calculate Limits: Maximum allowable hole size: Minimum allowable hole size: Where to Find and Download a DIN 7161 PDF legally
