In the world of industrial automation and motion control, space is often at a premium. That's where the pneumatic rodless cylinder comes into play — a compact, efficient alternative to traditional rod-type cylinders.
Rodless pneumatic cylinder that can provide linear motion without the need for external piston rods. The internal piston moves in the direction of the cylinder through changes in air pressure inside the cylinder.Very practical for modern industrial automation and manufacturing systems that require long travel distances
Rodless pneumatic cylinder will directly or indirectly connected to an external carriage with its air positon and actuateds it move along the direction of the cylinder. This external carriage carries the load or object you need to move.
When using rodless pneumatic cylinder, related parameters such as temperature, pressure, and speed should be considered.
◆ Rodless cylinders with magnetic coupling have no piston rod protruding from the cylinder block.
◆ The overall installation size is small, and the axial space is small, which saves about 44% of the axial space than the standard regular cylinders.
◆ Magnetically coupled pneumatic rodless cylinder can produce ultra-long stroke.
◆ The magnetic coupling type has a small shape and has mounting threads and nuts at both ends, which can be directly installed on the equipment.
The use of rodless pneumatic cylinder requires consideration of its structural characteristics and mechanism of action in order to better leverage its advantages and functions.
Space saving design:Without an external piston rod, rodless cylinders provide a more compact and streamlined form, allowing for long strokes even in limited spaces
Reduce bending and improve stability:The slide or slider runs along the guide rail or is magnetically coupled, providing better lateral stability and reducing bending moments on the pneumatic actuator compared to a single rod cylinder.
Cleaner operation and easier maintenance:Magnetic coupling rodless pneumatic cylinder is a sealed cylinder that can prevent pollution and reduce leakage, making it suitable for clean rooms or sanitary environments, with lower maintenance requirements compared to traditional rodless cylinders.
Fescolo specializes in providing the following four types of rodless pneumatic cylinder, which have different structures and characteristics and have their own application industries.
CY1B Series:Suitable for light-duty pushing, simple slide tables, and space-saving conveyor lines; ideal for low load, low precision, and non-side-load linear transfer applications.
CY1R Series:Equipped with a direct mounting base, offering improved guidance without a slider rail; suitable for space-limited environments that require quick installation.
CY1S Series:Fitted with a slide bearing guide, with relatively high friction; suitable for medium-load transfer, jig actuation, and conveying mechanisms.
CY1L Series:Equipped with a ball bushing bearing guide structure, offering high positioning accuracy; suitable for automated assembly lines, robotic sliders, and applications requiring repeated precision positioning.
The working principle of a cylinder without rod relies on the piston rod to transmit force, while a rodless cylinder transmits force through a magnetic coupling mechanism that connects an external load bearing slider and an internal piston.We take the mechanically coupledrodless cylinder as an example. Learn the specific working mode of rodless cylinder.
A cylinder barrel
An internal piston
A slider that moves along the cylinder
A magnetic coupling mechanism
End caps and air ports
Sealing ring
Whether with or without rods, the prerequisite for rodless cylinder operation is to maintain the sealing state of the cylinder, maintain air pressure, and prevent pollutants from entering.Here are its four working steps.
The rodless design can help users consider application industries with limited space more, as long travel and stability can greatly improve the efficiency of application industries.
Rod Type Cylinder: It pushes the load through the piston rod, with a simple structure but high rigidity and strong guidance, suitable for working conditions with high requirements for repeatability and stability. The total length is equal to the stroke+cylinder length+piston rod length, occupying a large amount of space.
Rodless air Cylinder: No piston rod, requires additional guide rails or slider support, slightly lower accuracy. The piston operated by compressed air to drive the external connecting slider to move, and the entire load runs on the side cylinder with a long stroke. The stroke is basically the same as the length of the cylinder body, saving installation space and making it very suitable for automated equipment with limited space.
Pneumatic rodless cylinders are not affected by rod overhang, bending, piston binding and uneven seal wear, rodless cylinders are ideal for applications in confined areas and long strokes where space is limited.
