What are the common types of electric push rods

Electric push rods, as an efficient and flexible transmission device, have been widely used in various fields such as industrial automation, fitness equipment, medical equipment, and home life. There are various classification methods for electric push rods, including classification based on screw form, motor type, appearance characteristics, and usage. Its diverse classification enables electric push rods to meet the needs of different application scenarios. This article will classify and introduce electric push rods according to their screw forms and motor types to help readers better understand electric push rod products.

Classified by screw form

1. Trapezoidal screw type electric push rod

The trapezoidal screw type electric push rod is a common type, and its screw adopts a trapezoidal thread design, which has high transmission efficiency and load-bearing capacity. This electric push rod is widely used in various applications that require linear pushing and pulling, such as material handling on production lines, assembly lines in automotive manufacturing, etc.

2. Ball screw electric push rod

Ball screw electric push rods are favored for their high precision and efficiency. The screw is transmitted through ball bearings, reducing frictional resistance and thus improving motion speed and accuracy. This type of electric push rod is particularly suitable for high load and high-speed application scenarios, such as precision machining, automated testing equipment, etc.

3. Planetary ball screw electric push rod

The planetary ball screw electric push rod combines the advantages of trapezoidal screw and ball screw, and has the characteristics of high strength, high efficiency, and long life. Its unique planetary ball design makes the push rod more stable and reliable during movement, suitable for various applications that require high precision and stability, such as aerospace equipment, precision measuring instruments, etc.

4. Planetary roller screw type electric push rod

The planetary roller screw type electric push rod is a more advanced type, which adopts the principle of planetary roller transmission and has higher transmission efficiency and load-bearing capacity. This type of electric push rod is usually used in heavy-duty, high-speed, or high-precision application scenarios, such as large mechanical equipment, precision machining equipment, etc.

Classified by motor type

1. DC motor type electric push rod

DC motor-driven electric push rods dominate in small electric push rods due to their high safety performance and easy control. This type of electric push rod is usually powered by a low-voltage DC power supply and has the characteristics of small size, light weight, and low noise.
