Rotary Airlock parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Airlock Rotor 1× Multi-vane rotor whose pockets carry powder past the seal while blocking air flow.
2 Servo Motor 4 parts 1× Brushless motor with an integrated encoder or resolver, driven in closed loop to hold commanded position, speed, or torque precisely.
3 Ball Bearing 2× Deep-groove radial ball bearing.
4 Oil Seal 2× Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
