Oil & Gas Precision Components
Custom Precision Sleeves for Oil & Gas Applications
SleeveMFG manufactures made-to-print shaft sleeves, wear sleeves, and precision bushings for demanding energy and fluid handling environments. We specialize in producing components that meet the specific dimensional, material, and surface finish requirements of Oil & Gas equipment, including pumps, valves, and rotating machinery.
Whether you require a one-off prototype for a field repair or high-volume production for OEM assembly, we machine components directly from your engineering drawings or 3D models.
Engineering Challenges in Oil & Gas Components
Components in the Oil & Gas sector operate under extreme conditions, including high pressure, high temperatures, and exposure to corrosive or abrasive media. Standard, off-the-shelf sleeves rarely provide the reliability required for critical rotating equipment.
Successful sleeve performance depends on precise control of geometry, materials, and surface condition across the full production run.
Concentricity and Runout
Essential for maintaining seal integrity and preventing vibration at high rotational speeds.
Surface Finish
Critical for minimizing friction and wear, particularly under mechanical seal faces.
Dimensional Stability
Maintaining precise fits (H6/H7) over long operational cycles despite thermal expansion.
Material Integrity
Selecting alloys that resist pitting, crevice corrosion, and hydrogen embrittlement.
Core Manufacturing Capabilities
SleeveMFG utilizes a combination of CNC machining and precision grinding to achieve the geometries required for energy sector applications. Our facility in Dongguan is equipped to handle complex profiles, including shoulders, flanges, and internal/external threads.
CNC Turning
Precision turning for diameters from Ø3 mm to Ø500 mm.
OD/ID Grinding
Achieving tolerances down to ±0.005 mm and surface finishes down to Ra 0.2 μm.
Centerless Grinding
Efficient processing for high-volume shaft sleeves and spacers.
Milling & Drilling
Keyways, oil holes, cross holes, and precision internal profiling.
Tight Tolerance Control
Maintaining concentricity, roundness, and cylindricity down to 0.01 mm.
Materials for Harsh Environments
We source and machine industrial metals specifically for the Oil & Gas supply chain. We maintain strict material traceability and provide certificates of conformity upon request.
Stainless Steels
316/316L for corrosion resistance; 17-4PH and 15-5PH for high-strength, precipitation-hardened applications.
Corrosion-Resistant Alloys
Inconel, Monel, and Hastelloy for sour gas service and aggressive chemical environments.
Alloy Steels
4140, 4340, and 42CrMo for high-stress structural components.
Bearing Steels
52100 and GCr15 for wear-critical sleeve applications.
Surface Treatments and Secondary Processes
Performance in the field often relies on the final surface treatment. SleeveMFG coordinates heat treatment and surface finishing to ensure your parts meet the specified hardness and wear requirements.
Heat Treatment
- • Quenching and tempering
- • Nitriding
- • Induction hardening to optimize core strength and surface hardness
Coatings
- • PVD/DLC coatings
- • Electroless nickel plating
- • Hard chrome plating to enhance wear resistance and reduce the coefficient of friction
Finishing
- • Precision honing
- • Polishing to meet specific Ra requirements for mechanical seal faces
Quality Assurance and Inspection
We operate under a rigorous quality management system. Every component is inspected against your drawing specifications before shipping.
Each inspection program is tailored to the part geometry and critical functional requirements.
CMM
Coordinate Measuring Machine for complex geometric verification.
Surface Roughness Testers
To verify Ra/Rz values on sealing surfaces.
Precision Gauging
Bore gauges, micrometers, and thread gauges for dimensional verification.
Profile Projectors
For checking radii, angles, and intricate profiles.
