Precision Pivot Bushing: Application & Engineering Review
Sleeve and flanged bushing geometry for a guided robot linkage or pivot assembly. This component geometry is presented to help engineering and purchasing teams specify a custom part. Final material, dimensions and suitability are defined by your approved design.
What problem should this part solve?
An unspecified shaft-to-bushing clearance can cause binding or excessive play after assembly. Start with the functional interfaces so that manufacturing and inspection work from the same acceptance criteria.
Material, process and inspection plan
| Application | Sleeve and flanged bushing geometry for a guided robot linkage or pivot assembly. |
|---|---|
| Manufacturing route | CNC turning and boring; machine locating diameters and end faces in a controlled sequence. |
| Material options to review | Stainless steel, brass or a specified bearing alloy selected against the mating shaft and lubrication. |
| Surface finish to specify | Deburring and controlled bore finish; evaluate any coating thickness before setting the final fit. |
| Critical inspection features | Bore diameter, outside diameter, concentric relationship, length and edge breaks. |
| Dimensions & tolerance | Made to the approved customer drawing. Supply overall dimensions in mm, datums, fits and feature-specific tolerances; final capability is confirmed after engineering review. |
| Prototype & production | Quote sample and repeat-order quantities separately. Lead time, inspection documents and delivery scope are confirmed in the quotation. |
Machining difficulty and practical solution
CNC turning and boring; machine locating diameters and end faces in a controlled sequence. Bore diameter, outside diameter, concentric relationship, length and edge breaks are the features to prioritize in the setup and inspection plan. Review tool access and workholding before freezing the drawing; agree any secondary operation rather than assuming it is included.
RFQ and sample approval checklist
Provide the CAD model and revision-controlled drawing, exact material grade, bore diameter, outside diameter, concentric relationship, length and edge breaks, required finish and prototype/production quantities. Identify the features that control assembly and state the reports needed for release.
- Approve the first-piece measurement scope and the applicable drawing revision.
- Confirm material documents, final finish and packaging needed for your assembly.
- Review the sample against mating parts before approving repeat production.
Can LXCET review a custom version?
Send your drawing for a feasibility review of CNC turned robot pivot bushing. The equipment and process guide explains listed machine ranges; the quality and inspection page explains how to define acceptance evidence. A machine’s travel or listed precision value is not a universal finished-part tolerance.
