Precision OD Grinding Services for Custom Sleeves
SleeveMFG provides precision Outside Diameter (OD) grinding for custom-machined sleeves, bushings, and tubular components. We specialize in producing parts that require tight dimensional control, specific geometric tolerances, and high-quality surface finishes for demanding industrial applications.
When Your Project Requires OD Grinding
Standard CNC turning is often sufficient for general-purpose components. However, OD grinding becomes a mandatory step when your sleeve design demands performance levels that turning alone cannot guarantee. We recommend precision grinding for:
Tight Fits
When components require precise H6/h6 or H7/h7 fits for bearings, seals, or housings.
Geometric Precision
When your drawing specifies strict tolerances for roundness, cylindricity, concentricity, or radial runout.
Surface Integrity
When the operating environment requires a surface finish (Ra) of 0.4 μm or finer to prevent seal wear or friction-related failure.
Hardened Materials
When the sleeve material has been heat-treated and requires stock removal to reach final dimensions.
Our Grinding Capabilities
We operate a range of grinding equipment in our Dongguan facility, allowing us to manage diameter requirements from small-batch prototypes to production runs.
Our grinding department supports centerless grinding for high-volume, straight-profile sleeves, as well as cylindrical grinding for stepped shafts, flanged sleeves, and parts requiring specific profile contours.

Quality Assurance & Inspection
Precision grinding is verified through rigorous inspection protocols. Every batch undergoes dimensional checks using calibrated equipment to ensure the ground surface meets the drawing specifications.
Surface Finish
Measured with digital surface roughness testers.
Dimensional Accuracy
Checked with calibrated micrometers and bore gauges.
Geometric Tolerances
Verified using CMMs and profile projectors to ensure concentricity and runout meet your requirements.
All orders are delivered with the requested documentation, including material certificates and inspection reports, ensuring full traceability for OEM and MRO applications.
