The double rod guided cylinder is a type of guided cylinder that combines ultra-high precision, excellent anti-lateral load capacity, double-acting drive, and powerful thrust in one unit.
Compared with the regular single-rod cylinder, the dual rod air cylinders(or double rod pneumatic cylinder) have a certain anti-torsion and anti-side load capacity, which can effectively prevent the rotation of the cylinder piston rod. Common dual rod air cylinders include TN, CXS, and STM series.
Guided pneumatic cylinder adds another guided rod on the basis of the single rod or double rod cylinders to make the movement trajectory of the cylinder more accurate, which can effectively increase the performance of resisting side load and reduce the influence of lateral swing. Most regular guided air cylinder is MGP series.
In the field of modern industrial automation, pneumatic systems have the advantages of rapid response, simple structure, and low cost, and are widely used in various types of mechanical equipment. There are various types of pneumatic actuators with guide Rod Mechanism play an important role in solving piston rod displacement, positioning errors, and enhancing load-bearing capacity due to its excellent guiding performance and high repeatability.
Double rod guided is a type of guided cylinder that adds dual guided rods and guiding mechanisms to traditional cylinders. Its design aims to enhance the lateral support and torque resistance of the piston rod during linear motion, ensuring that the piston can maintain stable and smooth operation even in high load and high-precision working environments. Suitable for automation systems that require smooth pushing and pulling movements, precise positioning, and a certain tolerance for off load or side load.
The dual rod pneumatic cylinder is a common type of pneumatic actuator.From its external appearance, its main feature is that there are two parallel piston rods connected to a single piston inside the cylinder.Let's analyze its main characteristics.
◆ Symmetrical thrust and tension:Due to the same area on both sides of the piston, the forward and reverse thrust after intake are consistent, making it suitable for symmetrical loads or bi-directional equal force applications.
◆ Superior bending and torsion resistance performance:The dual piston rod structure provides stronger resistance to lateral forces and is suitable for working conditions with certain lateral loads or eccentric forces.
◆ High guidance accuracy and smooth movement:The piston rod is supported in both directions, providing more stable movement and higher precision in repeated positioning.
◆ Suitable for clamping, pushing, and symmetrical mechanisms:Commonly used in applications such as fixture driving, positioning guidance, and synchronous pushing in automation equipment.
STMB,STMS Series Dual Rod Cylinder
Single guide rod cylinder: With only one piston rod and simple movement, it has two modes of single acting and double acting, suitable for linear propulsion scenarios with light loads and low precision requirements.
Double guide rod cylinder: equipped with two parallel piston rods, connected to the output through a slide block in the middle. This structure provides additional stability and directionality. Suitable for linear propulsion scenarios with heavy loads and high precision requirements.
Cylinder body: including cylinder body, cylinder head, sealing ring and other parts, it is the working chamber for compressed air.
Double piston rod: Two parallel arranged rods connect the piston and slider to achieve stable linear guidance.
Piston: Installed in the cylinder body, it is the core component of pneumatic drive.
Sliding block: connected to two piston rods, it is the output end, bearing loads and executing actions.
Guided bearing: provides precise guidance for the piston rod, reduces friction, and ensures motion accuracy.
The double guided pneumatic cylinder is a type of guided cylinder that integrates ultra-high precision, strong resistance to lateral loads, double-acting motion, and powerful thrust. Its working steps are as follows.
Intake driven piston movement
The piston rod drives the slider to move in a straight line
Guidance and anti torsion
Reversing action
In a double rod guided air cylinder, the slide block is not just a connecting component, it is the core driving and stabilizing structure of the entire guiding system. Its existence determines the motion accuracy, load-bearing capacity, and service life of the cylinder. It will give the dual rod cylinder the following four advantages:
Precise guidance to prevent deviation
Anti torsion, maintain load posture
Enhance load bearing capacity
Extend cylinder life
