Rodless cylinder vs electric cylinder -- technical performance and advantage analysis

Technical performance:

The same point of rodless cylinder and electric cylinder can work reliably in bad environment.

The rodless cylinder is very simple to operate without maintenance. And good at reciprocating linear motion, especially in the application of industrial automation more transfer requirements (workpiece linear transport). Only adjusting the single throttle valve installed on both sides of the rodless cylinder can achieve stable speed control. The electric cylinder is mainly used in the rotating and passive working conditions. Its advantage is that the response time is very fast. Through the feedback of signal, the speed, position and example can be precisely controlled. Moreover, there are higher requirements for the professional knowledge of working environment and operation and maintenance personnel.

Advantages of rodless cylinder:

(1) Strong adaptability. It can work normally in high and low temperature environment and has the ability of dust-proof and water-proof. It can adapt to all kinds of bad environment.

(2) Large output force. The output force of rodless cylinder is proportional to the square of cylinder diameter. The theoretical output force of a rod less cylinder with a diameter of 50 mm can reach 2000 n. for the electric cylinder with the same diameter, although the products of different companies are different, they are basically no more than 1000 n. Obviously, Rodless cylinder has more advantages in output force.

(3) The requirements for users are low, the principle and structure of rodless cylinder are simple, easy to install and maintain, and the requirements for users are not high.

Advantages of electric cylinder:

(1) The system structure is very simple. Because the motor is usually integrated with the cylinder block, plus the controller and cable, the whole system of the electric cylinder is composed of these three parts, simple and compact.

(2) Strong flexibility. There is no doubt that the flexibility of electric cylinder is much better than that of rodless cylinder.

(3) There are many stop positions and high control accuracy. Generally, the electric cylinder can be divided into low-end and high-end products. The stop positions of low-end products are 3, 5, 16, 64, etc., which vary according to different companies. The high-end products can reach hundreds or even thousands of positions. In terms of accuracy, the electric cylinder also has absolute advantages, with positioning accuracy up to ± 0.05mm, so it is often used in precision industries such as electronics, semiconductors, etc.
