VL-ST45 is an environmentally friendly and highly energy-efficient closed frame ballscrew actuator that replaces pneumatic cylinders with electro-mechanical components, offering a cleaner, quieter and energy-efficient operation. Contamination from lubricants, audible noise and damaging friction are greatly reduced.


The VL-ST45 is designed for increased speeds and efficiency. Component count is reduced, and the performance/cost ratio is excellent for the system which integrates an Animatics SmartMotor™ SM2315D as standard.
