Considerable power can be transmitted by junction power of fit.

Small power can be transmitted by junction power of fit.

Transmission of power cannot be done by only junction power of fit.

Hard to disassemble without damaging componets.

Capable of assembling and disassembling without damaging components.

without any slack.The part requires precision movement

Disassembling is often done. Ordinary fit parts.

The required condition that is good for lubrication. The general parts rotating or travelling.

Safety cost Production costWhen reducing costs.

Length of fit is long.Expansion occurs. Positioning error is large. Functionally, the part requires large clearance space.

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.

Shrinkage fit, cooling fit and strong press fit for large dimension components.Same as the above for assembling and disassembling.

Standard press fitting fix between iron and iron or between bronze and copper.

Fit that requires considerable power for assembling and disassembling.The key is required for large torque transmission.However, when non-ferrous components are fitted together, press fit power will be activated.

High-precision fixed mounting.The key is required for large torque transmission.Fit that requires considerable power for assembling and disassembling.

High-precision positioning that does not tolerate any clearance space.

Same as the above for assembling and disassembling.

High precision positioning.

Fit that can be assembled and disassembled by an ironhammer or handpress.The key or such items are required to prevent other components from rotating.

Fitting that allows assemble and disassemble using a wood or lead hammer.High-precision positioning where both are unmobile.Mounting parts that allow slight interference.

Stationary part that is not of great importance. Special precision travelling part.Fit that can be moved manually with using a lubricatorHigh grade positioning.

Precision travelling part.Fit that can be mobile in spite of small clearance spaceSpigot and positioning.The continuous rotary part of light load precision machine.

The general cold bearing part of grease or oil lubrication.

Fit that can be mobile due to proper clearance space.The general cold bearing part of grease or oil lubrication.

The bearing part that is working under the condition of high temperature, high speed and high load.High grade pressure feed lubrication The bearing part that has slight clearance space and good lubrication.It is fine even if there is a slight clearance space or the part requires clearance space.

It is fine even if there is a large clearance space or the part requiresclearance space.

The part requires proper clearance space in the high temperature. The part that can be enlarged to make clearance space to make assembly easier.It is fine even if there is a large clearance space or the part requires clearance space.
