It defines the permissible deviations (abmaße) from the nominal size, essential for hole-and-shaft systems.

is a historical German technical standard that specifies ISO deviations for internal dimensions (holes) for nominal sizes ranging from 1 mm to 500 mm . Published in August 1965, it defines the fundamental tolerances and limit deviations—such as H7, H8, and G7—required for precision engineering and manufacturing. Understanding "DIN 7161 PDF Extra Quality"

DIN 7161 applies to cylindrical and spherical plain bearings, which are designed to support radial and axial loads. These bearings are used in applications where there is a need for self-aligning, oscillating, or rotating movements. din 7161 pdf extra quality

Part 2: Tables of standard tolerance classes and limit deviations for holes and shafts. Should You Still Use DIN 7161?

Provides a close clearance fit. Used for precision location parts that need to move or rotate smoothly.

You can often find reliable, high-resolution documentation through official technical documentation platforms. 3. Core Components of the DIN 7161 Standard

If you successfully obtain a copy of DIN 7161, a very important question arises:

The standard covers the following bearing types:

"Extra quality" implies the file is unabridged, containing all the fundamental deviation formulas, baseline temperatures ( 20∘C20 raised to the composed with power C ), and usage guidelines.

This comprehensive guide breaks down the core concepts of DIN 7161, explains how to interpret its tolerance tables, and details why high-quality digital documentation is critical for modern manufacturing. What is DIN 7161?

Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Part 1: Basis of tolerances, deviations and fits.

It is essential to note that . For current projects, the global standard is DIN ISO 286-2 , which contains the updated tables for standard tolerance grades and limit deviations for holes and shafts.
