► Pneumatic actuator performance, structure and design
characteristics
1. Extruded aluminum ASTM6005 body with both internal and external
corrosion protection having honed cylinder surface for longer life
and low coefficient of friction.
2. Dual piston rack and pinion design for compact construction,
symmetric mounting position, high-cycle life and fast operation,
reverse rotation can be accomplished in the field by simply
inverting the pistons.
3. Multiple bearings and guides on racks and pistons, low friction,
high cycle life and prevent shaft blowout.
