Q: What is the current version of DIN 7161? A: The current version of DIN 7161 is DIN 7161-12/2019.
: It covers workpieces with a nominal size of up to 500 mm . [1]
The standard defines four tolerance classes: din 7161 pdf
The shaft is always smaller than the hole, ensuring free movement or rotation. Rotating shafts, hinges, sliding components. H7/g6 or H8/f7

The shaft is always larger than the hole, requiring force, heat, or cold contraction to assemble. Gears on shafts, bushings, permanent assemblies. H7/p6 or H7/s6 The Transition: DIN 7161 vs. ISO 286 [1] The standard defines four tolerance classes: The
The minimum allowable limit from nominal. Fundamental Deviation: The limit closest to the zero line. How to Find a Legitimate DIN 7161 PDF
In an interference fit, the shaft is intentionally larger than the hole. Joining the parts requires significant force, thermal expansion/contraction, or a hydraulic press. Once assembled, the friction locks the parts together.
Even though DIN 7161 was superseded by DIN ISO 286-2 in 1990, it remains highly relevant for:
It is much easier and cheaper to manufacture a variety of precise shaft diameters using turning or grinding than it is to buy or create custom reamers and drills for non-standard holes. The Shaft-Basis System (Standard Shaft)
