Types Clearance Fits Transition Fits Interference Fits Preferred Fits Using the Basic Hole System Symbol Description H11/c11 Loose running fit for wide commercial tolerances or allowances on external members. Free running fit not for use where accuracy is essential, but good H9/d9 for large temperature variations, high running speeds, or heavy journal pressures. H8/f7 Close running fit for running on accurate machines and for accurate location at moderate speeds and journal pressures. H7/g6 Sliding fit not intended to run freely, but to move and turn freely and locate accurately. H7/h6 Locational clearance fit provides snug fit for locating stationary parts; but can be freely assembled and disassembled. H7/k6 Locational transition fit for accurate location, a compromise between clearance and interference. H7/n6 Locational transition fit for more accurate location where greater interference is permissible. Locational interference fit for parts requiring rigidity and H7/p6 alignment with prime accuracy of location but without special bore pressure requirements. H7/s6 Medium drive fit for ordinary steel parts or shrink fits on light sections, the tightest fit usable with cast iron. H7/u6 Force fit suitable for parts which can be highly stressed or for shrink fits where the heavy pressing forces required are impractical.
