• Materials: 304/316 stainless steel, 6061/7075 aluminum, C36000 brass, phosphor bronze, PEEK, PTFE
• Wall thickness capability down to 0.5 mm for lightweight sleeve designs
• Surface treatments: anodizing (Type II/III), electroless nickel plating, hard chrome, passivation
• Random-sampling CMM inspection with full statistical process control (SPC) reporting

Applications

• Hydraulic and pneumatic cylinder barrels for industrial machinery
• Motor housing sleeves for precision spindle assemblies
• Bearing race sleeves for rotating equipment in mining and power generation
• Guide sleeves for linear motion systems in automation and robotics
• Thin-wall isolation sleeves for electrical and thermal barrier applications

Quality Assurance

Every component manufactured by AOOM Technology undergoes our multi-tier quality assurance framework, which is rooted in ISO 9001:2015 certified processes and supplemented by industry-specific standards. Our quality system encompasses first-article inspection (FAI) with full dimensional reports, in-process statistical process control (SPC), and final validation using coordinate measuring machines (CMM) with measurement uncertainty as low as 0.001 mm. Material certifications, process traceability, and compliance documentation are provided with every shipment, giving our clients complete confidence in the integrity and repeatability of their production parts.
