Fitting calculator

The KRW fitting calculator is based on the ISO tolerance system of DIN EN ISO 286 (2019) and covers a nominal dimension / diameter range from 30 mm to 2,500 mm. The result shows the maximum and minimum clearance / interference as well as the type of fit.

Tapered roller bearings are not considered.

KRW takes no responsibility for the correctness of the results.
