CNC Turned Sleeves

Detailed Description

Our CNC turned sleeves are produced for applications requiring a tubular component with accurately controlled inner and outer geometry. They can function as spacers, protective covers, bearing supports, alignment components or mechanical connection elements.

CNC turning allows external diameters, internal bores, shoulders, threads and grooves to be produced within an efficient machining sequence. Secondary drilling, milling and surface treatment can be integrated where more complex installation or connection features are required.

Available Surface Finishes

• Anodizing: Improves corrosion resistance and surface appearance of aluminum sleeves.
• Black Oxide: Common protective finish for carbon steel components.
• Nickel Plating: Provides additional corrosion and wear resistance.
• Passivation: Suitable for stainless steel sleeves used in demanding environments.

Structural & Functional Breakdown

• Tubular Sleeve Structure: Provides separation, protection or alignment around shafts and assemblies.
• Stepped Bore Structure: Supports different internal mating diameters.
• Threaded Sleeve Structure: Internal or external threads allow direct mechanical connection.
• Shouldered Sleeve Structure: Machined shoulders provide axial positioning.

Key Features

• Controlled Bore Geometry: CNC boring supports consistent internal dimensions.
• Concentric ID/OD Machining: Helps maintain alignment between internal and external cylindrical surfaces.
• Thin-wall Machining Capability: Machining strategy can be adjusted to reduce deformation in thinner sleeves.
• Flexible Feature Integration: Threads, grooves, holes and shoulders can be added according to drawings.

Applications

• Machine Assemblies
• Hydraulic Systems
• Bearing Supports
• Industrial Automation
• Mechanical Spacers & Protectors
