The structural features of sleeve components


According to the structural features,the sleeve precision components can divide into:bearing sleeve with supporting revolved body,shaft sleeve,jig bush and guide sleeve on the clamp.cylinder liner on the internal combustion engine,hydraulic cylinder for the hydraulic systems,valve bush for electro-hydraulic servo valve,cooling jacket for the motorized spindle,etc.


The structure and dimensions of sleeve components are different for different use.But the structures of sleeve components all have the same features as below:

1.       The outside diameter d is always smaller than the length L,generally,the L/d<5.

2.       The difference between the outside diameter and inside diameter is always small.

3.       The requirement of concentricity between the outside hole and inside hole is high.

4.       The structure is always simple.


Runsom Precision have produce lots of sleeve components and also shaft components.If you need to produce these sleeve components like bearing sleeve,shaft sleeve,light ring,etc,please send email to You can also visit our website for more information.Thanks.
