Din 7161 Pdf Extra Quality

The shaft is explicitly designed to be larger than the hole. Assembly requires force, thermal expansion (heating the hole), or cryogenic shrinking (cooling the shaft).

To ensure safety and accuracy in engineering, it is recommended to obtain technical standards through official channels. The official publisher for DIN standards.

The lower deviation of the hole is zero. The fit is determined by varying the size of the shaft. din 7161 pdf extra quality

Common Example: (used for precise locating pins where parts must be accurately aligned but still disassembleable). Interference Fits

Allowing for text search and quick navigation through tables. The shaft is explicitly designed to be larger than the hole

When examining a DIN 7161 data sheet, tolerances are expressed using an alphanumeric code (e.g., H7, g6). This code consists of two vital parts:

Scan across the top row to locate the specific tolerance designation required for your design (e.g., g6 for a shaft or F7 for a hole). The official publisher for DIN standards

: It aligns with ISO/R 286-1962 , though it contains specific modifications and additions for general-purpose holes used in German industry.
