Custom Machined Distance Sleeves
SleeveMFG specializes in the precision machining of custom distance sleeves for industrial assemblies. We manufacture components that meet the exact dimensional, material, and tolerance requirements specified in your engineering drawings.
We do not supply standard catalog parts. We machine custom sleeves for OEMs, MRO providers, and industrial distributors who require specific fits, geometric control, and material properties.
Precision Engineering for Assemblies
Distance sleeves serve critical functions in rotating equipment, including pumps, gearboxes, motors, and mechanical seals. Accurate axial positioning, proper clearance, and load distribution depend on the precision of these components.
Dimensional Accuracy
Tight control over length and wall thickness to ensure proper stack-up in your assembly.
Concentricity & Runout
Essential for high-speed rotating equipment to minimize vibration and premature bearing or seal failure.
Surface Finish
Precision grinding to Ra 0.2 μm or lower to ensure optimal seal performance and bearing fit.
Geometric Control
Strict adherence to perpendicularity and parallelism, preventing binding or misalignment during installation.

Secondary Operations
Distance sleeves often require specific surface treatments to resist wear, corrosion, or fatigue. We coordinate the following processes as part of our manufacturing workflow.
Heat Treatment
Quenching, tempering, nitriding, and induction hardening.
Surface Coatings
Black oxide, zinc plating, electroless nickel, hard chrome, and PVD/DLC coatings.
Finishing
Precision grinding, honing, and polishing.
How to Order Custom Distance Sleeves
We manufacture directly from your technical documentation. To receive an accurate quote, please provide the following information.
Engineering Drawings
PDF, DWG, DXF, or STEP/IGES files.
Material Specifications
Grade or mechanical property requirements.
Quantity
From prototype quantities to production batches.
Tolerance & Finish
Specific fit requirements (e.g., H7/h6) or surface finish calls.
If you have a worn part or a sample, we can reverse-engineer the sleeve to match the original dimensions and tolerances.
