Coal Mill Vertical Shaft Bearing Tolerances

Bearing tolerances Standard values The tolerances for the dimensions and running accuracy of bearings are set out in ISO 492/199/582. This largely corresponds to DIN 620. Accuracy of rolling bearings › Tolerances for bore and outside diameters, ring and bearing width › Tolerances for inscribed and circumscribed circle diameters of rollers
