WebPreferable fits of the shaft-basis system (ISO 286-1:2010) Note: For economic reasons, the first choice for a fit should, whenever possible, be made from the tolerance classes shown with green color. The tables below report the preferable zones of tolerance for standard couplings from the UNI norms. ZONE OF TOLERANCE RECOMMENDED FOR SHAFTS WebRFS: No Clearance, Interference Fit. Figure 3. Part with Regardless of Feature Size Condition: As the location accuracy is of the utmost importance, there is no relationship between the hole size and the position tolerance (Pin tolerance indicates a press fit and no clearance). Design Intent: High and Robust Location Accuracy
