Custom Machining for OEMs, MRO & Industrial Distributors
Custom Shaft Protection Sleeves: Precision Machined to Your Drawing
SleeveMFG specializes in the manufacturing of custom shaft protection sleeves for OEMs, MRO facilities, and industrial distributors. We do not supply off-the-shelf catalog parts — we machine components directly to your engineering drawings, 3D models, or physical samples.
Whether you are protecting pump shafts from abrasive media or extending the service life of rotating equipment in high-load environments, we provide the metallurgical expertise and machining precision required for critical fitments.

Engineered for Performance and Longevity
Dimensional integrity under demanding operating conditions
Shaft protection sleeves must maintain precise dimensional integrity in service. Our production process is focused on the critical requirements of rotating equipment:
H6 / H7
Tight Bore/Shaft Fits
We machine for precise H6/H7 or custom fits to ensure seamless installation and prevent fretting corrosion.
0.01 mm
Geometric Precision
Concentricity, roundness, and radial runout controlled to within 0.01 mm, minimizing vibration and seal wear.
Ra 0.2 μm
Surface Finish
Finishes down to Ra 0.2 μm, essential for maintaining mechanical seal integrity and reducing friction.
±0.005 mm
Dimensional Control
OD/ID grinding and CNC turning capabilities hold tolerances of ±0.005 mm on critical diameters.
Materials for Harsh Environments
Industrial metals matched to your application
We machine shaft protection sleeves from a wide range of industrial metals, selected based on your specific application — whether it involves chemical exposure, high temperatures, or abrasive wear.
Stainless Steel
316/316L for corrosion resistance; 410/420/17-4PH for superior hardness and wear resistance.

Full Manufacturing Cycle
Secondary Processes for Enhanced Durability
A precision sleeve often requires more than just machining. We manage the full manufacturing cycle, coordinating secondary operations to ensure your components arrive ready for assembly.
Discuss Your SpecificationHeat Treatment
Quenching, tempering, nitriding, and induction hardening to optimize surface hardness.
Surface Coatings
Hard chrome plating, electroless nickel, PVD, and DLC coatings to provide additional protection against wear and corrosion.
Finishing
Precision honing and polishing to meet specific surface roughness requirements for seal compatibility.
Manufacturing Capabilities
From miniature sleeves to large-diameter components
One production floor covers the full size envelope and the precision values your fitments demand.
