Planetary roller screw servo linear unit

The fully integrated planetary roller screw (PGT) enables translatory movements with stroke lengths from 50 to 3000 mm. The linear unit with separate servo motor is a powerful, energy-efficient and clean alternative to the hydraulic or pneumatic cylinder for lifting plate or rack and pinion movements.
