Key Features
Aerospace-Grade AL7075-T651 Aluminum
Constructed from premium aerospace aluminum alloy, this sleeve delivers excellent mechanical strength and long-term stability, making it suitable for precision CNC aluminum components, industrial fixtures, and motion-control systems.
AC Micro-Arc Oxidation (MAO) Surface Finish
The entire surface is treated with micro-arc oxidation, achieving a uniform 10–15 μm oxide layer. This enhances wear resistance, surface hardness, and corrosion protection, ensuring long-lasting performance in harsh environments.
High-Precision Coaxiality
All circular features, including the internal threaded holes centered on the main axis, maintain a tight coaxiality tolerance of 0.01 mm. This ensures smooth rotation, accurate fitment, and reliable functional alignment.
Controlled Dimensions
Overall Height: 76 mm
Outer Diameter: Φ60 mm
Inner Diameter: Φ47.6 mm
These dimensions allow stable installation and consistent performance in precision assemblies.
Applications
High-strength aluminum sleeves for mechanical assemblies
Precision fixtures and jigs
Motion control components
Aerospace and automotive assemblies
