## What is h7 g6?

Close running fit for running on accurate machines and for accurate location at moderate speeds and journal pressures. H7/g6. G7/h6. Sliding fit not intended to run freely, but to move and turn freely and locate accurately.

## How do you calculate tolerance?

Tolerance Calculation Formulasc = a – b. Upper limit dimension of the closing element:c max = a max – b min Lower limit dimension of the closing element:c min = a min – b max Tolerance of the closing element (subtracting equation 3 from equation 2)c max – c min = a max – a min – (b min – b max ) Such as.T c = T a + T b
