If your project requires the shortest possible positio
ning cylinder and the highest possible force density due to space constraints, electric positio
ning cylinders ba
sed on inverted roller screw drive are compact positio
ning cylinder types and provide high force density. Inverted means the spindle nut rotates into place, driving the spindle in and out. Our DAXX line offers electric executive cylinders with inverted roller screw drive, integrated servo motor and rotary encoder. The force is up to 22kN.
Electric cylinders with inverted roller leads are very compact because the spindle nut is fitted with a permanent magnet. The servo motor is centrally constructed around the spindle nut. Therefore, the spindle nut is also the main rotor of the motor. This can save a lot of space, otherwise the motor must be connected in series or parallel to the shaft.
Positioning cylinder variants with water cooling are available to significantly improve cycle rates (e.g., for projects using servo welding guns)
