Electromechanical linear actuators
NIASA F/A Series linear actuators are electro-mechanical devices designed for precise linear movement, suitable for harsh environments due to their high sealing. They consist of a round stem within a steel or aluminum tube, driven by an electric motor and screw/nut mechanism.
These actuators offer high precision, energy efficiency, and reliability, supporting axial loads from 3.5 kN to 86 kN. They feature various screw types and materials, with options for anti-rotation and magnetic sensors. The outer tube can be steel or aluminum.
Applications include shutter systems, drive systems, scissor lifts, and antenna orientation systems, each utilizing specific configurations and accessories for optimal performance.
The F Series uses steel tubes, while the A Series uses aluminum tubes, offering trapezoidal and ball screw options. Configurations include in-line motoreducers, parallel drives, and 90º drives, with models like M205, M501, and M505.
Accessories such as tilt supports, flanges, clevis rods, limit switches, and sensors enhance actuator adaptability and functionality.
NIASA provides custom solutions tailored to specific actuator requirements beyond standard offerings.
Options for alternating or stepper motors are available, with recommendations for motors with brakes to prevent position loss. Standard brakes are typically sufficient for most motor sizes.
Various configurations (M501, M505, M601, M605) are detailed, highlighting coaxial motoreducers and pulley ratio modifications for desired transmission ratios.
Tables specify screw diameters, pitches, and load capacities for different models (F16 to F50), including maximum axial strength and motor power requirements.
Standard drives use AC motors with aluminum pulleys and polyurethane toothed straps, detailing power availability and motor flange types.
Guidelines for calculating drive torque and power requirements emphasize safety coefficients and start-up torque calculations.
Lubrication intervals depend on work type and cycle, with recommendations for automatic lubrication systems and specific grease types. A complete cleaning and grease change is recommended every five years.
Appropriate corrosion protection should be selected based on environmental conditions, following DIN EN ISO 12944-2 standards. NIASA should be contacted for higher corrosion resistance needs.
- C3: Medium urban and industrial atmospheres with moderate SO2 pollution.
- C4: High industrial and coastal areas with moderate salinity.
- C5-I: Very high industrial areas with high humidity.
- C5-M: Very high maritime areas with high salinity.
- Low (L): 2 to 5 years
- Medium (M): 5 to 15 years
- High (H): More than 15 years
NIASA actuators offer an IP65 protection index as standard, with higher levels available upon request, defined by DIN EN IEC 60529.
For environments below -20ºC or above +40ºC, contact NIASA for suitable materials and sealing components.
Optional configurations include immobilizations, special configurations for higher speeds, and various mounting and drive adaptations.
Includes size, configuration, reduction, screw type, stroke, immobilization, and accessories.
Detailed parts list for F and A series actuators, including body, caps, screws, nuts, bearings, seals, and more.
Custom modifications are available for specific requirements, including special flanges, trunnion mounts, and compact units.

LINEARtube | A SERIES: aluminum tube ACTUATORS F SERIES: steel INTRODUCTION NIASA F/A Series linear actuators are electro-mechanical cylinders in which a round stem moves inside a second tube, of either steel or aluminum. The lengthwise movement of the stem is achieved with the combination of an interior screw/nut which drags it, and an electrical motor that drives the screw/nut. The power transmission from the motor may be direct or by means of different gear solutions and toothed belts. Against solutions with exposed screws, protecting them with an external stem means that the equipment is...
