China Factory: Your One-Stop Rodless Pneumatic Cylinder Manufacturer for Efficient Automation Solutions

Our China-based factory, a leading manufacturer of rodless pneumatic cylinders, offers a comprehensive range of efficient automation solutions. These cylinders, devoid of a conventional piston rod, harness magnetic or mechanical coupling to transform the piston's motion into linear movement of the slider, thus achieving a frictionless drive. This innovative design significantly reduces wear and tear while enhancing the efficiency and lifespan of the cylinders. As a trusted manufacturer in China, we are dedicated to providing top-tier rodless pneumatic cylinder solutions to meet your automation needs.

Working principle of rodless pneumatic cylinder

The working principle of the rodless pneumatic cylinder is mainly based on the pneumatic principle and is a new type of pneumatic actuator. When compressed air enters the cylinder, it pushes the piston forward, which drives the slider to move linearly along the guide rail through a magnetic coupling or mechanical coupling device. Since there is no direct physical connection between the slider and the piston, rodless driving is possible, reducing energy loss and noise. With its unique structural design, it eliminates the piston rod in the traditional cylinder, thereby providing greater stroke and power output while saving space. This design makes rodless pneumatic cylinders particularly popular in applications where space is limited.

Main functions of rodless pneumatic cylinder

rodless pneumatic cylinders have a variety of functions, including but not limited to: high-precision positioning, high-speed movement, long stroke, low noise, low friction, easy installation and maintenance, etc. These functions make rodless pneumatic cylinders widely used in automated production lines, CNC machine tools, medical equipment, plastic machinery and other fields.

High-precision positioning: This feature makes it excellent in automation systems that require strict position control and can meet the needs of precision manufacturing and assembly.

High-speed movement: Due to the optimization of the internal structure and advanced pneumatic control technology, the rodless pneumatic cylinder can achieve fast and smooth reciprocating movement, thereby significantly improving production efficiency.

Long stroke: For automation equipment that requires a wide range of linear motion, rodless pneumatic cylinders provide a reliable solution and can achieve long-distance linear motion without the need for additional transmission mechanisms.

Low noise: In terms of noise control, rodless pneumatic cylinders also perform well. Its unique design produces extremely low noise during operation and will not cause any disturbance to the working environment and operators.

Low friction: The low friction characteristics ensure that the rodless pneumatic cylinder can maintain stable performance during long-term operation, reduce energy consumption and wear, and extend the service life.

Types and models of rodless pneumatic cylinders

Magnetic coupling rodless pneumatic cylinder: The piston of the magnetic coupling rodless pneumatic cylinder is sealed in the cylinder barrel by the end cover. There is no direct mechanical connection between the piston and the slider, but between the magnet on the piston and the magnet on the inside of the slider. magnetic coupling together. This kind of cylinder has the advantages of compact structure, smooth movement and low noise.

Mechanical rodless pneumatic cylinder: The mechanical rodless pneumatic cylinder has a groove in the axial direction of the cylinder barrel, and the piston and slider move in the upper part of the groove. In order to prevent leakage and dust, sealing tapes and dust-proof stainless steel tapes need to be used at the opening to be fixed on the cylinder heads at both ends. The piston frame passes through the groove to connect the piston and the slider. The piston and the slider are connected together to drive the actuator fixed on the slider to achieve reciprocating motion.

In China, GXR, as an important factory and manufacturer of rodless pneumatic cylinders, provides various types and models of rodless pneumatic cylinders to meet the needs of different customers. For example, the MXY series rodless pneumatic cylinder has a bore size ranging from 6mm to 12mm and a stroke range of up to 400mm. It has the characteristics of double acting, long stroke, built-in buffer and magnetic switch. In addition, there are MXF, MXU, MXJ, MXP, MXH, MXQ, MXS, MXW and other models to choose from to meet the needs of different application scenarios.

The difference between rodless pneumatic cylinder and rod cylinder

Structural differences:

rodless pneumatic cylinder: There is no external piston rod extending or retracting, and the rodless design is achieved through a special structure (such as the coupling of a strong magnetic piston magnetic group and a strong magnetic slider magnetic group). Compact structure, saving space.

Rod cylinder: has a piston rod fixed to the piston. The piston rod transmits motion and force directly. The structure is relatively complex and takes up a lot of space.

Differences in working principles:

rodless pneumatic cylinder: When air pressure acts on the piston, the piston is pushed into motion. The slide and the piston are coupled magnetically or mechanically, so the slide also passively moves with the piston.

Rod cylinder: When air pressure acts on the piston, the piston and piston rod move outward at the same time. As a stressed component, the piston rod directly transmits motion and force.

Function and application differences:

rodless pneumatic cylinder: saves space, can withstand high direct loads, has self-guiding function, is suitable for cantilever loads, balanced driving force at both ends, variable and diversified strokes, light weight, built-in adjustable air buffer, long-lasting lubrication effect, Superior running and stopping performance, high reliability and operational performance as well as easy maintenance and long life. However, the sealing performance is poor and external leakage is prone to occur. Usually used in feeding or grabbing situations, such as door switches, feeding manipulators, clamps, etc.

Rod Cylinder: Inexpensive, easy to install and easy to operate. The total cylinder extension length exceeds twice the stroke, piston rod bending will accelerate wear, lack of self-guiding function, poor positioning performance, and inconsistent extension and retraction speeds. At the same time, it cannot directly support the load. Usually used in situations where linear motion output is required, such as machine tools, automated production lines, industrial machinery, etc.

The purpose of rodless pneumatic cylinder

rodless pneumatic cylinders are used in a wide range of applications, including but not limited to: material handling, positioning and assembly on automated production lines; tool replacement and workpiece positioning on CNC machine tools; precision control in medical equipment; mold opening and closing and plastic injection in plastic machinery wait. These applications fully demonstrate the important position of rodless pneumatic cylinders in the field of industrial automation.

Factors to consider when choosing a rodless pneumatic cylinder

The bore size and stroke range of the cylinder: are basic and crucial factors. This needs to be determined based on the specific application scenario to ensure that the cylinder can provide sufficient power and work stably within the required stroke.

Working pressure and flow requirements: Different application scenarios have different requirements for the working pressure and flow of the cylinder, so it is necessary to carefully evaluate and select the appropriate cylinder model to meet these requirements.

Positioning accuracy and repeatability: In some precision applications, the positioning accuracy and repeatability of the cylinder directly affect the performance and stability of the entire system. Therefore, when selecting a rodless pneumatic cylinder, special attention needs to be paid to these indicators.

Working environment and temperature requirements: are also factors that must be considered. The cylinder needs to be able to work stably in various harsh environments, including high temperature, low temperature, humidity and other environments. Therefore, when selecting a cylinder, you need to ensure that its material and design meet these requirements.

Manufacturer service and price: Choosing a manufacturer with a good reputation and complete after-sales service can ensure that the quality and performance of the cylinder are guaranteed. At the same time, the factory's reasonable price is also an important factor to consider when choosing a cylinder.
