VEVOR 12V Linear Actuator OK648-1000N: 12-inch stroke, 220 lb thrust

The VEVOR OK648-1000N is a 12-volt linear actuator, a motor-driven rod that pushes and pulls in a straight line. It has a 12-inch (300 mm) stroke and 1000N (about 220 lb) of thrust, and it comes with a mounting bracket. People use actuators like this for adjustable furniture, small lifting platforms, hatches and DIY automation. Here is what the specifications mean.

How a linear actuator works

Inside the housing, a small DC motor turns a screw through a gearbox, and the screw moves the rod in or out. Reversing the polarity of the 12V supply reverses the direction. Most actuators include limit switches to stop the rod at each end of travel. A basic setup needs a suitable 12V DC power supply and a switch or controller that can reverse the polarity.

Stroke and length

The stroke is 12 inches (300 mm). Retracted, the actuator measures 16.73 inches (425 mm) and extended it is 28.73 inches (725 mm). These lengths matter for mounting: you need room for the full extended length, and the mounting points must be positioned so that the rod's travel moves your load as intended.

Speed and force

VEVOR lists a travel speed of 0.55 in/s (14 mm/s), so a full stroke takes roughly 22 seconds. Thrust is 220 lb (1000N), which VEVOR describes as suited to medium-duty tasks like lifting platforms and motorised doors and windows. With actuators, force and speed trade off against each other, and the stated thrust is a maximum. Leave a margin, and remember that levers and hinge geometry change the force the actuator actually sees.

Power and duty cycle

The rated voltage is DC 12V and the current draw is 5 amps. The duty cycle is 25%, a figure that tells you how much of the time the actuator should run. In general, a 25% duty cycle means short runs followed by rest, for example about two minutes of running in every ten, so it suits occasional adjustment more than continuous cycling. Check the manual for the exact definition.

Noise and dust and splash protection

VEVOR states a noise level below 50 dB. Actuators make a motor and gear sound whenever they move. The IP54 code means protection against dust ingress and splashing water, as the brand says, with a caution that water must not get inside the motor. IP54 does not cover immersion or jets of water, so outdoor installs usually benefit from some shelter.

Size and weight

The packaged item measures 16.7 x 3.0 x 1.6 inches (42.4 x 7.6 x 4.1 cm) and weighs 2.7 lb (about 1.2 kg).

Who it suits

It suits hobbyists and makers building adjustable desks, motorised covers, small lifts and similar projects at home or in a workshop, where moderate thrust and an occasional duty cycle fit the task.

What to check before you buy

• Load: work out the real force needed, including leverage and any friction, and leave a margin.
• Space: confirm there is room for the 28.73-inch extended length and for the bracket.
• Power supply: check that your 12V supply can deliver at least the 5 amps stated.
• Control: you will need a reversing switch or controller, which may be sold separately.
• Duty cycle: make sure the way you will use it stays within the 25% limit.
