All limits shown in chart below are in thousandths of an inches. Symbols H8,e7, etc. are Shaft and Hole designations used in American-British-Canadian System (ABC). Limits for Shaft and Hole are applied algebraically to the Nominal (basic) size to obtain the limits of the size for the parts. All data given in bold in the chart below are in accordance with ABC agreements. The values given under the "Clearance Limits Column" represent min and max amounts of clearance resulting from application of standard tolerance limits.

RC7; Free Running Fits: This kind of fits are intended to use where accuracy is not essential. It is suitable for great temperature variations. This fits are suitable to use without any special requirements for precise guiding of shafts.
