CHENGSHUO / AUTOMATION & MOTION
When a small part sets the whole assembly. Review the shafts, pins and sleeves that locate, guide and connect your mechanism.
Explore relevant studies Application illustration START WITH FUNCTION
A useful review starts with the assembly. Assembly function, mating components, critical fits and inspection conditions.
These application pages help engineering and sourcing teams define a custom requirement. Part suitability is confirmed through the drawing review; the examples do not imply a qualified end use.

Work through your next decision. APPLICATION STUDY 01 Illustration Automation & motion
Connect shaft diameters, shoulders and grooves to the mating assembly, then define the datum setup and acceptance checks before quoting.
Fit & alignment Inspection
APPLICATION STUDY 02 Illustration Automation & motion
Separate bore, outside diameter and installation conditions so a sleeve can be reviewed against the way it will actually be assembled and measured.
Fit & alignment Inspection
Bring your component into the review. Assembly function, mating components, critical fits and inspection conditions.

Shaft fit & assembly alignment Connect shaft diameters, shoulders and grooves to the mating assembly, then define the datum setup and acceptance checks before quoting.
Engineering Quality
Start the review with Map the mating interfaces Mark the bearing or sleeve contact, locating shoulder, retained end and any clearance-only regions on an annotated view. Include the relevant mating-part requirements, not necessarily the entire assembly model. Identify whether a groove locates another component or merely provides clearance. This makes it possible to discuss each feature against its actual job.
Resolve the drawing references Identify the applicable drawing standard and revision, then confirm datum features, their order and the geometric controls required by the design. Ask how the same references will be established during inspection. Record questions about incomplete or conflicting callouts instead of translating an informal request for concentricity into a different requirement without approval.
Review the complete manufacturing condition Ask the supplier to review support, access to shoulders, secondary features and the state in which final checks occur. A Swiss-type route may be a candidate for a slender turned part; the drawing, material and actual equipment configuration determine suitability. If heat treatment or coating is specified, identify which requirements apply after that operation.
The linked Chengshuo shaft and pin are published geometry references. They do not establish a completed motion-system application, measured alignment result or verified process capability. This guide is a project-review framework, not a customer case report.
Automation & motion / APPLICATION STUDY
Sleeve fit & thin-wall interfaces Separate bore, outside diameter and installation conditions so a sleeve can be reviewed against the way it will actually be assembled and measured.
Engineering Quality
Start the review with Separate the functional surfaces Mark the bore, outside locating surface, flange seat and clearance regions. Supply the relevant housing and shaft requirements where they influence acceptance. Identify whether the sleeve is a spacer, guide or another type of component in your assembly; that function is a customer input, not something established by the example product name.
Define the measurement condition State whether sizes and geometric requirements apply to the free part, a specified restrained condition or the installed assembly. Agree how the part will be held without obscuring the characteristic being checked. Where suppliers and incoming inspection use different methods, compare those methods before approving a sample report.
Review edges, finishing and protection Identify insertion edges, transitions and any surface that must remain free of handling marks. Confirm finishing specifications, permitted edge breaks and the point at which final dimensions are accepted. Discuss the proposed machining and measurement approach for the actual wall geometry. Agree protective packaging where contact between parts could affect a specified surface.
The brass sleeve and aluminum washer links document published component forms. The washer is an annular geometry reference, not evidence of a sleeve application. Installation behavior, thin-wall limits and measurement results require project-specific review.
