Key benefits Lightweight and strong construction: a hollow titanium alloy shaft with a fully hollow center delivers strength while reducing weight. Durable and waterproof design: the middle shaft features waterproofing and durability for challenging environments. Integrated, clean assembly: titanium alloy hollow shaft paired with a 7075 aluminum alloy shaft bowl; the shaft bowl locking method is aligned with the body shaft for a secure, streamlined fit. Easy installation and reliable fit: designed to work with the integral middle shaft installation tool through a hollow square hole interface, ensuring correct alignment and firm connection. Robust, longlasting performance: materials and design chosen for durability and consistent performance in demanding applications. Compatibility and versatility: suitable for configurations that require a strong hollow shaft with a reliable locking interface and lightweight construction. Use scenarios Robotics and automation: drive shafts in servo motors and robot joints where weight reduction and strength are essential, and reliable locking is required. Precision machinery: CNC, milling, and other precision equipment that benefit from a hollow titanium alloy shaft with a durable, secure bowl structure. Outdoor or damp environments: tooling or equipment exposed to moisture or harsh conditions can benefit from the waterproof middle shaft and corrosionresistant titanium alloy construction.
