Custom Machined Sleeves Made to Your Drawings
SleeveMFG specializes in the precision machining of custom sleeves for industrial rotating equipment. We do not sell catalog parts; we manufacture the exact component your assembly requires—whether you are repairing a legacy pump with an obsolete sleeve or scaling production for a new OEM motor design.
Obsolete Sleeve Replacement & Reverse Engineering
When an original equipment manufacturer (OEM) stops supporting a machine, finding replacement parts often delays critical repairs. We assist MRO teams and maintenance departments by producing obsolete shaft and wear sleeves that are no longer available on the market.
If you have a worn-out component, we can reverse-engineer it from a physical sample or your original technical drawings. We work with your specific material requirements—including hardened tool steels or corrosion-resistant alloys—to ensure the replacement sleeve meets or exceeds the original's performance in the field.
Send us the worn component; our engineering team will measure, document, and quote against the original geometry.
Provide 2D or 3D files and material specs—we manufacture strictly to your approved print.
Built for Breakdown Recovery
We help maintenance teams recover equipment quickly by producing legacy parts that are no longer available through the OEM channel.
- No OEM support required for legacy parts
- Hardened tool steels and corrosion-resistant alloys
- Field performance equivalent to or better than the original
Precision Manufacturing Capabilities
Our Dongguan facility operates with a focus on tight-tolerance cylindrical geometry. We combine CNC turning with secondary grinding operations to achieve the fits required for bearing journals, mechanical seals, and shaft interfaces.
| Parameter | Capability |
|---|---|
| Outside Diameter | Ø3 mm – Ø500 mm |
| Inside Diameter | Ø1 mm – Ø450 mm |
| Part Length | Up to 1500 mm |
| CNC Turning Tolerance | ±0.01 mm |
| Precision Grinding Tolerance | ±0.005 mm |
| Concentricity / Runout | Down to 0.01 mm |
| Surface Finish | Down to Ra 0.2 μm |
Material Selection for Industrial Environments
The longevity of a sleeve depends on the alloy's interaction with the operating environment. We maintain an inventory and supply chain for the following materials to support rapid project startup.
Stainless Steels
304, 316, 17-4PH, 15-5PH for corrosive fluid handling and marine applications.
Carbon & Alloy Steels
1045, 4140, 4340 for high-load power transmission components.
Bearing & Tool Steels
52100, D2, GCr15 for high-wear environments requiring extreme surface hardness.
Specialty Alloys
Inconel, Monel, and Hastelloy for extreme chemical or thermal resistance.
Secondary Processes for Performance
A precision sleeve is rarely finished once it leaves the lathe. To provide a ready-to-install component, we manage the entire secondary process chain. This reduces your administrative burden and ensures that heat treatment and coatings are applied to the correct specifications.
Discuss Your Finish Requirements →Quenching, tempering, induction hardening, and nitriding to increase wear resistance.
Hard chrome plating, electroless nickel plating, and PVD/DLC coatings for friction reduction.
Honing and centerless grinding for critical fits (H6/H7).
Why OEMs and Maintenance Teams Partner with SleeveMFG
Drawing-Based Production
We manufacture strictly to your provided 2D drawings or 3D models. If you only have a sample, our engineering team will generate the necessary documentation for your approval.
Flexible Volume
Whether you require a single prototype for a breakdown repair or a batch of 500 units for an OEM production run, our setup is designed to handle both.
Supply Chain Integration
Being located in Dongguan provides us with direct access to specialized surface treatment and heat-treating facilities, allowing us to maintain tight control over quality and lead times.
Clear Documentation
We provide material test reports and inspection data with every order to ensure your quality assurance requirements are met.
Request a Quote for Your Sleeve Components
To receive a prompt quotation, please send your technical drawings or 3D files (PDF, STEP, DWG, or DXF) to our engineering team. Include details regarding the material grade, quantity, and required tolerances.
