SMC mechanical rodless cylinderworking principle

The MY1B series isMechanical joint rodless cylinderBy relying on mechanical sliders and rigid connections with internal pistons, the traditional piston rod structure is eliminated, and linear reciprocating motion is achieved through pneumatic drive.

1. Structural CoreThe cylinder tube is equipped with a piston inside and a sliding slider on the outside, which passes through the piston and the external sliderMechanical coupling structureRigid connection, integrated synchronous motion; The cylinder body is equipped with end caps and buffer components at both ends, matched with seals and wear-resistant guide rails to ensure motion accuracy and sealing.

   
   

2. Driving operation principleCompressed air is separately connected to the air ports at both ends of the cylinder, and the airflow direction is controlled by reversing the intake direction:

• One end intake and the other end exhaust, the air pressure pushes the internal piston to move in a straight line;

• The piston drives the external slider to slide synchronously through mechanical connection, outputting thrust;

• By switching the direction of the air inlet and outlet, the slider can move back and forth in a straight line.

3. Sealing and leak proof designThe opening of the cylinder body adoptsSpecial steel strip sealing structureThe inner and outer double-layer steel strip sealed cylinder body slots: the inner sealing steel strip isolates compressed air, and the outer dust-proof steel strip blocks dust and debris, which not only prevents air pressure leakage but also adapts to harsh working conditions, ensuring stable operation of the cylinder.

   
   

4. Buffer and SensingBoth ends of the cylinder are equipped with pneumatic buffers/optional hydraulic buffers to reduce impact at the end of the stroke, noise, and vibration; The cylinder body can be equipped with a magnetic switch, coupled with a piston magnetic ring, to achieve stroke position signal induction, facilitating precise control of automation equipment.

   
   

5. Core Advantage PrincipleCompact structure without piston rod, greatly saving installation space; Mechanical rigid connections have strong load-bearing capacity, stable load, and high repeatability positioning accuracy, making them suitable for automation scenarios such as long-distance, straight line transplanting, handling, and push-pull.

Key points of selection

◆Load verification: The guide rail load rate should be calculated based on the actual load mass, static torque, and impact torque. The sum of all load rates should be ≤ 1 to ensure stable cylinder operation and avoid overload damage.

◆Installation method adaptation: Select the corresponding load verification curve according to the installation direction (horizontal/vertical/top/wall); Among them, the vertical installation and descent working conditions need to focus on checking the buffering capacity to prevent damage to the equipment caused by impact at the end of the stroke.

◆Buffer unit selection: When the impact at the end of the stroke exceeds the standard air buffer range, an A/L/H hydraulic buffer unit should be selected to reduce the impact force, noise, and equipment loss.

◆Magnetic switch matching: D-M9 □/D-A9 □ series magnetic switches are preferred, and they need to be accurately matched according to the voltage and output type (NPN/PNP) of the equipment control circuit to ensure accurate position sensing and stable signal transmission.
