24V Tubular Linear Actuator

• The body is 304 stainless steel, not coated steel or aluminium extrusion. Two moments matter. Cleaning: it takes the same agents as the machine frame, and there is no paint edge to chip and start corrosion. Condensate: units in chilled cabinets, vented enclosures or glazed facade frames collect standing water, and bare austenitic steel tolerates that where a coating blisters.
• Internally the gear train is copper alloy. Metal teeth keep their profile under repeated load and do not creep when the unit is parked under static load for months.
• Protection sits on a board outside the tube. It stops the rod at both ends of travel, so the stroke does not depend on external stops. It also cuts power at 0.32 A when current climbs because the mechanism has jammed. That is what protects the motor: a stalled DC motor turns electrical energy into heat in the winding before anything mechanical fails. A jammed flap, a hatch frozen shut or a slide packed with debris all show up as current.
• IP65 covers dust and low-pressure water jets, not immersion, and not sustained high-pressure or solvent washdown, which attacks the rod seal rather than the shell. The seal is the weakest part: grit carried past the wiper and side load that deflects the rod both shorten it. Service life follows rod cleanliness and load alignment, not wall thickness.
• The 8,000-12,000 cycles are rated-condition figures. Three variables pull them down: how much of the load is concentric, how continuous the cycling is, and the air temperature inside the enclosure.

• With the power off, the gear train holds 300 N. That is what keeps a cover, flap or hatch where it was left, with no brake and no standby current.
• Three practical results. A battery-powered system does not spend capacity keeping a cover shut. A power cut leaves the mechanism where it was, not open. Holding costs no wear, because nothing turns.
• 300 N resists steady back-driving. It is not a brake: impact and shock belong to the mechanism stop, not to the gear train.

Window and Vent Automation

Smart factory exhaust windows, automatic basement vent covers, and Luxury Yacht Ventilation Windows.

Airflow Control Systems

Large-scale HVAC dampers, laboratory precision airflow distribution doors, and industrial exhaust baffles.

Smart Building Projects

Remote-controlled high-altitude airtight windows and motorized deployment for vertical curtain wall decorative elements.

All five variants share the 16 mm body, the 24 V DC drive, the 20 kg rating and the 3 mm/s speed. Travel is the only variable in the part number, and five machine types account for most of what ships.

• 10 mm - Micro Linear Actuator 10 mm: lane stops and diverter gates on parcel sorters, flap doors on packaging machines. Short throw, high cycle count, two end positions.
• 20 mm - Mini Linear Actuator: latch pins and door catches on battery swap cabinets and pack housings, where the position has to hold with the cabinet unpowered.
• 30 mm - Compact Linear Actuator: cable-port covers and inspection windows on roadside and telecom cabinets, where dust and jet wash drive the design.
• 50 mm - Micro Linear Actuator 50 mm: access covers on agricultural and construction machinery, held closed against vibration and washed down at the end of a shift.
• 100 mm - Small Linear Actuator 100 mm: service doors on energy storage cabinets and charging units, where the door has to swing clear before the panel comes out.

Set the stroke from the movement the mechanism needs plus a small overlap at each end, not from the space left in the frame: extra stroke adds installed length and cost, not capability.

Each variant carries its own specification page: Micro Linear Actuator 10 mm, Mini Linear Actuator, Compact Linear Actuator, Micro Linear Actuator 50 mm and Small Linear Actuator 100 mm. The platform sits inside the wider electric linear actuator range, alongside other body diameters, voltages and force classes.
