Product Parameters
Unique Seal Structure
The piston seal in the SDA40X50 adopts a heterogeneous two - way seal structure. This design has several advantages. Firstly, it has a compact dimension, which is in line with the overall compact design of the cylinder. Secondly, it has a grease - retaining function. The ability to retain grease helps to lubricate the moving parts, reducing friction and wear. Additionally, the two - way seal effectively prevents air leakage from either side of the piston, ensuring that the compressed air is used efficiently to generate the desired force.
Working Principle
The SDA40X50 operates on the principle of using compressed air to drive the piston within the cylinder. When compressed air is introduced into one side of the piston through the appropriate port, the pressure of the air forces the piston to move in the opposite direction. As the piston moves, it pushes the piston rod, which is connected to the external load or mechanism. When the air supply is reversed, the piston moves in the opposite direction, completing a full cycle of operation. This simple yet effective working principle enables the cylinder to provide reliable linear motion for various industrial applications.
