Precision Bearing Support Sleeves: Custom Machined to Your Specifications
SleeveMFG specializes in manufacturing bearing support sleeves for industrial equipment where dimensional accuracy and material integrity are non-negotiable. We operate as an extension of your engineering team, producing components directly from your CAD models or 2D technical drawings.
We do not supply off-the-shelf catalog parts. Instead, we focus on the specific geometric requirements of your assembly — ensuring the correct fits, concentricity, and surface finishes required to extend the service life of your bearings and rotating components.

Why Precision Matters
Engineered for Performance and Fit
Bearing support sleeves function as critical interfaces in pump shafts, gearboxes, and motor assemblies. When these components fail to meet precise tolerances, it leads to premature bearing wear, vibration, and mechanical failure. Our machining process is designed to mitigate these risks by focusing on three areas:
Controlled Bore / Shaft Fits
We machine to specific H6/H7 or h6/h7 fits, ensuring the sleeve seats correctly without requiring field modification.
Geometric Stability
Through controlled CNC turning and precision grinding, we maintain strict concentricity and perpendicularity, minimizing radial runout during high-speed rotation.
Surface Integrity
We offer various surface finishes down to Ra 0.2 μm, reducing friction and preventing wear in high-load applications.
Technical Specifications
Manufacturing Capabilities
We utilize a combination of CNC turning, milling, and OD/ID grinding to achieve the exact profile required by your assembly.
- CNC turning & milling for complex profiles and features
- OD/ID precision grinding for tight tolerance fits
- Full geometric control from Ø1 mm bores to 1500 mm lengths

Service Levels
From Prototyping to Production
We understand that different project stages require different service levels — and we scale our process to match.
R&D and Prototyping
We provide small-batch, high-precision samples to help you validate your design before moving to final production.
MRO and Maintenance
We can reverse-engineer worn or obsolete bearing sleeves from physical samples, allowing you to get critical machinery back online without waiting for OEM lead times.
OEM Production
We maintain consistent quality across large production runs, ensuring that the 100th piece matches the 1st piece in every dimension.
One Supplier, Complete Package
Secondary Operations
To reduce your supply chain complexity, SleeveMFG coordinates all necessary secondary operations in-house or through our vetted partner network. This ensures you receive a finished, ready-to-install component.
Include Treatments in Your QuoteHeat Treatment
Induction hardening, quenching, and tempering to increase surface hardness.
Surface Coating
Hard chrome plating, electroless nickel, and PVD/DLC coatings for extreme wear resistance.
Finishing
Precision honing and polishing to achieve specific micro-texture requirements.
