In the hole basis system, the size of the hole is kept constant and shaft sizes are varied to obtain various types of fits. In this system, lower deviation of hole is zero, i.e. the low limit of hole is same as basic size. The high limit of the hole and the two limits of size for the shaft are then varied to give desired type of fit.
Some of the application and some of the selected Preferred Fits for Hole and Shaft Basis system have been given followed by Fits explanations. Free Running; This type of tolerance can be usable where any special requirements …

The othercompression plateshallbe plain rigid bearing block. The bearing faces of both plates shall be preferably larger than the nominal size of the test piece to which the load is applied.
During the rolling process the rollers bow slightly, which results in the sheet metal being thinner on the edges. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the Manufacturer's Standard Gauge, which has no inherent tolerances.

Grain size is denoted by a number indicating the number of meshes per liner inch (25.4 mm) of the screen through which the grains pass when they are graded after crushing. The following list ranging from very coarse to very fine includes all the ordinary grain sizes commonly used in the manufacture of grinding wheels.
