ISO Bore Tolerance Chart. For bore tolerance system, Nominal sizes from 1 - mm DIN (). Nominal dimension. Tolerance Zones over to U7 S7 R7 . The hole basis fits have four preferred hole tolerances (H11, H9, H8, and H7); the shaft The above shaft tolerances are now covered in the new ANSI B B. Preferred Tolerances in Metric. C. ISO Tolerances (External Measurements) . . ISO , ANSI B, BS and AS are preferred tolerance.

Note: In each column, the upper figure is the upper dimensional tolerance, and the lower figure is the lower dimensional tolera nce. Hole tolerance range class.

✓When the tolerance allowed is sufficiently greater than the process variation, no difficulty arises. ✓The difference between the upper and lower limits is termed. Therefore design acceptable tolerances must be determine which indicate how much tolerances are used on the functional features of the part to specify the. Variations on dimensions without tolerance values are according to "DIN ISO GENERAL TOLERANCES FOR LINEAR AND ANGULAR DIMENSIONS (DIN. ISO Tolerances for Holes (ISO ). Nominal hole sizes (mm). over. 3. 6. 18 . inc.

Steps involved in the Evaluation of Limits of Tolerances. Selection of an Appropriate FIT based on functional requirement. Selection of Type of Shaft and Hole. 4. Outline. • Basic Definitions. • ISO system for Tolerance Specification. • Tolerance Design for assembly- Fits. • Design of Limit Gages. • Taylor's Principle.
