The part which can be enlarged to make clearance space to make assembly easier. The part which requires proper clearance space in the high temperature. The part which allows a large clearance space or the part requires clearance space. The bearing part which is working under the condition of high temperature, high speed and high load (high grade pressure feed lubrication) . The bearing part which has slight clearance space and good lubrication. The part which allows a slight clearance space or the part requires clearance space (high grade fit) . The general cold bearing part of grease or oil lubrication. Fit which can be mobile due to proper clearance space (high grade fit) . The continuous rotary part of light load precision machine. Fit which can be mobile in spite of small clearance space (spigot and positioning) . Precision traveling part. Stationary part which is not of great importance. Special precision traveling part. Fit which can be moved manually with using a lubricator (high grade positioning) . Fit which can be assembled and disassembled by wood or lead hammer. High-precision positioning where both are unmobile. Mounting part which is given a little leeway. High-precision positioning. Fit which can be assembled and disassembled by an iron hammer or hand press . (Key or such items are required to prevent other components from rotating) . Fit which requires considerable power for assembling and disassembling. High-precision positioning which does not tolerate any clearance space. Same as the above for assembling and disassembling High-precision fixed mounting. (Key or such items are required for large torque transmission.) Fit which requires much power for assembling and disassembling. (Key or such items are required for large torque transmission.) However, when non-ferrous components are fitted together, press fit power will be activated.Standard press fit fixing between iron and iron or between bronze and copper. Same as the above for assembling and disassembling Shrinkage fit, cooling fit and strong press fit for large dimension compo-nents. Fixed firmly together, so that permanent assembling can be sought with shrinkage fit, cooling fit and strong press fit for assembling. Press fit for light alloy. Functional classification Functionally, the part which requires large clearance space Production cost For reducing Length of fit is long. Expanse. Positioning error is large. Safety cost The part which requires precision movement without any slack. Ordinary fit parts. The general rotating or traveling part. (Disassembling is often done.) (The condition of good lubrication is required.) Transmission of power cannot be done by only junction power of fit. Capable of assembling and disas-sembling without damaging components. Hard to disassemble without damaging components. Small power can be transmitted by junction power of fit. Considerable power can be transmitted by junction power of fit. Application example Fit of loosening safety pin Piston ring and piston ring groove Piston ring and piston ring groove Exhaust valve cage and traveling part of spring sheet Crank web and pin bearing ( Side surface) Flexible plate coupling and gear ( active side) Fixation of gear and shaft ( small torque)Stopper Pins STPN(p6) Insertion of valve guide for inlet valve Dowel Pins MST(p6) Printed in red are listed with applicable examples of mold parts.
