When choosing micro linear actuators, you need to understand the relevant parameters of the lower putter. If you understand the parameters, then how to choose is simple. The parameters of the push rod include: Stroke: the distance range that your wheelchair needs to be adjusted. If the stroke is too short, it will not reach the design index, and if the stroke is too long, it may break the wheelchair. Installation distance: After the push rod is fully retracted, the distance between the center of the front and rear positioning holes. This distance should also be calculated according to the specific conditions of the wheelchair. Improper installation size will cause the backrest movement to be inconsistent with the design movement index, or even damage the wheelchair. Speed ​​and load: The speed of the push rod is inversely proportional to the load, which can be selected according to the product. Voltage: Subject to the power supply voltage that you can provide. Power: The power of a small electric push rod is basically 50W, which is enough for a wheelchair. As for the shape of the slider installed on the front and rear of the push rod, the aperture on the slider can be comprehensively determined by the push rod manufacturer and its own products.
