All data given in bold in the chart belowĪre in accordance with ABC agreements. Limits for Shaft and Hole are applied algebraically to the Nominal (basic) size to obtain the limits of the size for the parts. are Shaft and Hole designations used in American-British-Canadian System (ABC). Graphical Representation of ANSI B4.1-1967 Running and Sliding Fits Table Running and Sliding Limits and Fits For Cylindrical Parts Īll limits shown in chart below are in thousandths of an inches. Loose running fits exposed to effects of corrosion, contamination by dust and thermal or mechanical deformations. With this fits, The parts with great clearances with having great tolerances. RC8 and RC9 Loose Running Fits: This kind of fits are intended for use where wide commercial tolerances may be required on the shaft. This fits are suitable to use without any special requirements for precise guiding of shafts. It is suitable for great temperature variations.
