ISO Tolerances

Our app is a fit calculator that is addressed to students, employees, and apprentices (trainees) in all technical sectors. It calculates all information about a fit by entering a basic size in a matter of seconds in accordance with DIN EN ISO 286 norm.

We designed this app to help you calculate tolerances of inner and outer features of journal bearings, linear bearings, thrust bearings, bushings, ball bearings, roller bearings, housings, cylinder bores, drilled holes, linear and precision shafts, pistons, etc.

Included tools:

- Shaft tolerance calculator: Outputs the upper and lower limit as well as the tolerance field of the shaft.

- Hole tolerance calculator: Outputs the upper and lower limit as well as the tolerance field of the hole.

- Linear tolerances charts;

- Tolerance charts for angles;

- Chamfer tolerances;

No responsibility is taken for the completeness and correctness of displayed data.
