Preferred Fits

Shaft BasisIn the Shaft basis system, the shaft is kept as the constant, and hole upper and lower deviation values determine the type of fit. In the shaft basis system, the upper deviation of the shaft will be Zero.	Hole BasisIn a hole basis system, the hole is kept as the constant, and the shaft upper and lower deviation values determine the type of fit. In a hole basis system, the Lower deviation of the hole will be Zero.	Description/Application
Clearance Fits
C11/h11	H11/c11	Loose Running Fit- Wide commercial tolerances, used where accuracy is not essential
D9/h9	H9/e9	Free Running Fit- High running speeds, large temperature variations, heavy pressures and where accuracy is not essential
F8/h7	H8/f7	Close Running Fit- Accurate location at moderate speeds on accurate machines
G7/h6	H7/g6	Sliding Fit- Accurate location where components are intended to move and turn freely but not run freely
H7/h6	H7/h6	Locational Clearance Fit- Snug fit for locating stationary components which need to be freely assembled and disassembled
Transition Fits
K7/h6	H7/k6	Locational Transition Fit (Tap Fit)- Accurate location where assembly requires gentle persuasion
N7/h6	H7/n6	Locational Transition Fit- More accurate location where assembly permits greater interference
Interference Fits
P7/h6	H7/p6	Locational Interference- Prime accuracy of location where assembly requires alignment and rigidity
S7/h6	H7/s6	Medium Drive Fit (Press Fit)- For assembly of steel parts and shrink fits on light sections
U7/h6	H7/u6	Force Fit (Press Fit)- For assembly of components where high pressures and stresses are permitted
