Precision Sleeves for Automation Equipment
Automation equipment requires mechanical components that deliver consistent motion, precise alignment, and long service life. Standard catalog parts often fail to meet the specific clearance, material, or dimensional requirements of custom automated systems. SleeveMFG machines precision sleeves to customer drawings, supporting the exact needs of automation OEMs and system integrators.

From raw material procurement to final inspection and surface finishing.
Custom Manufacturing for Automation Systems
Automation machinery operates under varied load conditions, often requiring components with specific fits such as H7/g6 or H7/k6 to ensure smooth operation. We operate as a direct extension of your engineering team, producing sleeves that integrate directly into your assemblies without the need for secondary rework.
We accept 2D drawings and 3D models (STEP, IGES, DXF) to manufacture parts that match your design intent. Whether you require a single prototype for a new machine design or a batch of 500 units for production assembly, our process is built for flexibility.
Send Your DrawingsDesign files accepted
2D drawings and 3D models in STEP, IGES, and DXF formats, manufactured to match your design intent.
Engineered fits
Specific clearance and transition fits, including H7/g6 and H7/k6, for smooth operation under varied loads.
Prototype to production
From a single prototype for a new machine design to batches of 500 units and beyond for production assembly.
Drop-in integration
Sleeves arrive ready to assemble into your automation systems, with no secondary rework required.
Technical Capabilities for Automation Components
Automation components demand strict control over geometry. We utilize CNC turning and precision grinding to achieve the tolerances necessary for high-speed or high-load automation applications.

| Outside Diameter | Ø3 mm – Ø500 mm |
| Inside Diameter | Ø1 mm – Ø450 mm |
| CNC Turning Tolerance | ±0.01 mm |
| Precision Grinding Tolerance | ±0.005 mm |
| Concentricity | Down to 0.01 mm |
| Surface Finish | Down to Ra 0.2 μm |
| Production Volume | Prototype to Batch Production |
Common Sleeve Applications in Automated Machinery
We manufacture a variety of sleeve configurations used throughout automated assembly lines, material handling equipment, and robotics.
Guide Sleeves
Machined for precise linear guidance and alignment of moving machine parts.
Bearing Sleeves
Precision-ground housings that maintain proper bearing fits and prevent premature failure.
Spacer Sleeves
Used for precise axial positioning of components on shafts or in housings.
Shaft Sleeves
Protection for shafts in high-wear areas, or to adapt shaft diameters to specific bearing or seal sizes.
Precision Bushings
Thin-walled or heavy-duty components for pivot points and rotational assemblies.

The choice of material dictates the service life of the sleeve in automated environments. We machine a comprehensive range of metals to meet your hardness, corrosion resistance, and weight requirements.
Secondary treatments
We coordinate heat treatment (induction hardening, nitriding, quenching) and surface coatings (hard chrome, electroless nickel, PVD) to improve wear resistance in high-cycle applications.
Stainless Steel
304 · 316 · 17-4PH
Used for cleanroom automation, food processing, and corrosive environments.
Carbon & Alloy Steel
4140 · 42CrMo · 1045
Selected for high-strength applications where parts are subject to significant mechanical stress.
Tool & Bearing Steel
52100 · GCr15 · D2
Ideal for hardened sleeves requiring high wear resistance and dimensional stability.
Aluminum Alloys
6061 · 7075
Used where weight reduction is critical to the performance of moving parts.
Quality Control and Dimensional Precision
In automation, a deviation of a few microns can lead to system-wide vibration, misalignment, or failure. Our inspection process is tailored to verify that the manufactured part matches the print.
Inspection equipment
Concentricity and Runout
Critical for rotational speed and smooth, vibration-free operation.
Fits Verification
Verification of ID/OD tolerances for press fits or slip fits.
GD&T Compliance
Adherence to complex profiles and positional requirements specified in your drawings.
