CNC Machined Aluminum Alloy Industrial Robot Arm Joint Mounting Sleeve – Precision Custom Robotics Structural Parts
Description
This product is a specialized mounting sleeve designed exclusively for industrial robot arm joints. Fabricated from 6061-T6 aluminum alloy and precision-machined via 5-axis CNC milling, it serves as a core structural component that ensures stable connection and precise power transmission of robot joints. Engineered to meet the requirements of industrial/collaborative robot joint modules with a load capacity of ≤50kg, the product features surface treatments such as hard anodizing to significantly enhance surface hardness (HV≥120) and protection performance (IP54 dust and water resistance, upgradable to IP65), making it suitable for harsh industrial environments with temperatures ranging from -10℃ to 60℃.
Boasting high-precision assembly capabilities, the product achieves key dimensional tolerances of up to ±0.02mm, flange surface flatness of ≤0.01mm, and coaxiality of dual mounting holes of ≤0.015mm—ensuring seamless integration with joint shafts, reducers, and other components. It supports customization based on customer CAD drawings, including dimensions (main mounting holes available in Φ60-Φ100mm), threaded hole specifications (M6/M8 optional), and laser-engraved marks, catering to the customized assembly needs of various robot models.
Manufactured in strict compliance with ISO 9001 and ASTM B209 aluminum alloy standards, the product undergoes multiple quality inspections such as coordinate measuring machine (CMM) testing and hardness verification to guarantee consistency and reliability in mass production. It is widely used for the assembly and integration of various robot joint modules, including those in industrial automation production lines, collaborative robots, and material handling robots.
