Marine Precision Components
Custom Marine Shaft Sleeves & Precision Rotational Components
In the marine and offshore industry, shaft sleeves are critical to the integrity of propulsion systems and rotating equipment. SleeveMFG provides custom-machined shaft sleeves designed to withstand harsh maritime environments, delivering the dimensional accuracy and surface integrity required for mechanical seals and bearing fits.
We manufacture components directly from your engineering drawings, CAD models, or physical samples, ensuring a precise match for your specific equipment requirements.
Capabilities
Precision Engineering for Marine Applications
Marine environments demand high-performance materials and exacting tolerances to prevent premature wear and fluid leakage. We specialize in components that require tight control over concentricity, roundness, and surface finish.
Corrosion-Resistant Materials
Machining of 316L, 17-4PH, 15-5PH stainless steel, Monel, and other high-strength alloys.
Tight Tolerances
CNC turning and precision grinding to achieve H6/H7 fits for bearing and seal interfaces.
Surface Integrity
Surface finishes down to Ra 0.2 μm to minimize seal wear and extend the service life of mating components.
Complex Geometries
Integration of keyways, cross holes, snap-ring grooves, and flanged profiles as specified in your design.

Surface Treatment
Secondary Processes and Surface Treatments
To ensure your marine shaft sleeves survive saltwater and high-pressure conditions, we coordinate a full suite of secondary operations.
Surface Hardening
Nitriding, induction hardening, and carburizing to increase wear resistance.
Protective Coatings
Hard chrome plating, electroless nickel plating, and PVD/DLC coatings to enhance corrosion resistance.
Precision Finishing
Honing and polishing for optimal seal performance.
Why Partner
Why Partner with SleeveMFG
Made-to-Print Manufacturing
We do not provide standard catalog parts. We manufacture the exact sleeve your drawing demands. Whether you are replacing an obsolete part for a legacy pump or sourcing components for new marine propulsion systems, we follow your technical specifications for material, tolerance, and finish.
Prototype to Production
We support the full product lifecycle. From single-piece prototypes for repair projects to low-volume production for niche marine equipment, we offer the flexibility to meet your quantity requirements without compromising on quality or documentation.
Supply Chain Consolidation
Managing multiple vendors for machining, heat treatment, and surface coating is inefficient. We act as a single-source partner, coordinating the entire manufacturing process and performing final quality inspections in our Dongguan facility before shipment.
