Product Description
AZ91D Magnesium Alloy Vacuum Die Casting Robot Motor Press Ring
HighBroad casts AZ91D magnesium alloy motor press rings and bearing retainers for robot joint actuators. These small ring components hold bearings and motor stacks in position; vacuum die casting keeps them dense and dimensionally stable while magnesium saves grams at each joint, which accumulates across a multi-axis robot.
Key Features
- Dense vacuum casting for thin ring sections
- Precise bore and face machining for bearing fit
- Light weight saves mass at every robot joint
- Stable dimensions maintain preload settings
- Good damping reduces vibration transfer
- Micro arc oxidation prevents galvanic corrosion with steel bearings
Applications
Press rings, bearing retainers and spacer rings inside servo motors, harmonic drive actuators and integrated robot joint modules.
