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.
