The working principle of the magnetic coupling rodless cylinder is to use the permanent magnet inside the hollow piston rod to drive another magnet outside the piston rod to move, so as to realize the reciprocating movement of the load connected to the external magnet. When the piston is pushed by the air pressure in the cylinder barrel, the piston moves. At the same time, the magnetic ring in the external slider moves synchronously under the influence of the magnetic line of force of the magnetic ring on the piston. It is characterized by a small overall installation size and small axial space, about 50% less axial space than a standard cylinder. And the axial load performance is superior, which can withstand certain lateral and eccentric loads.

Pneulead brands include the CRY series， CRYS series, and CRYL series. Among them, the CRY series and CRYS series can provide 16, 20, 25, 32, and 40mm bore sizes. And the magnetic holding force of the CRY series can be from 137N to 920N, and CYRS can be selected from 140N to 850N. The CRYL series is available in 10,16,20,25,32, and 40-mm bore sizes, and its magnetic holding force can range from 60N to 850N. The piston speed of three of them is 50-400mm/s.CRY series can be selected from the basic type and direct installation type. The basic type cannot be installed with a magnetic switch. The direct installation type is with a switch track and magnet inside. CRYS series is a guide rod type, sliding bearing with magnetic switch rail. CRYL series is also a guide rod type, which is a ball bearing with a magnetic switch rail for mounting.

Design Considerations of Rodless Cylinder

Rodless cylinders offer advantages in certain applications by providing extended stroke lengths without the need for a traditional piston rod extending from both ends. Design considerations for rodless cylinders involve various factors to ensure optimal performance, reliability, and efficiency. 
Type of Rodless Cylinder:
There are different types of rodless cylinders, such as cable cylinders and magnetic rodless cylinders. Choose the type that best suits the application requirements, considering factors like load capacity, speed, and precision.
Stroke Length:
Determine the required stroke length for the application. Rodless cylinders are known for offering longer strokes compared to traditional cylinders with piston rods. Consider the available space and the desired travel distance.
Guidance Mechanism:
Select an appropriate guidance mechanism for the rodless cylinder. Common options include linear ball bearings, roller guides, or other types of slide mechanisms. The guidance system ensures smooth and precise linear motion.
Drive Mechanism:
Rodless cylinders can be powered by various drive mechanisms, such as pneumatic, hydraulic, or electric drives. Choose the drive mechanism based on factors like speed, force requirements, and the type of power source available in the application.
Sealing and Contamination Prevention:
Implement effective sealing systems to protect the internal components from contaminants. Seals help prevent the ingress of dust, debris, and other particles that could compromise the performance and lifespan of the rodless cylinder.
Load Capacity and Force Requirements:
Consider the load capacity and force requirements of the application. Rodless cylinders should be selected based on their ability to handle the specific loads and forces encountered during operation.

What are the Different Types of Rodless Cylinders?

Rodless cylinders are pneumatic or hydraulic cylinders that do not have a traditional rod extending from one end. Instead, they utilize different mechanisms to move the load along the axis of the cylinder. There are several types of rodless cylinders, each with its own design and advantages. 
Belt-Driven Rodless Cylinders:
These cylinders use a belt or band mechanism to transmit force along the cylinder's axis.The belt is typically made of reinforced rubber or other durable materials.Belt-driven rodless cylinders are known for their smooth and precise linear motion.
Cable-Driven Rodless Cylinders:
Similar to belt-driven cylinders, cable-driven rodless cylinders use cables instead of belts for transmitting force.The cables are often made of steel and are guided along the length of the cylinder to provide linear motion.
Magnetic Rodless Cylinders:
These cylinders use magnetic fields to move the piston inside the cylinder.Magnetic rodless cylinders are often used in applications where a contact-free and clean linear motion is required.
Guided Rodless Cylinders:
Guided rodless cylinders have internal guide systems that keep the load stable during linear motion.These guides can be in the form of linear bearings, rollers, or other mechanisms that prevent lateral movement.
Band-Driven Rodless Cylinders:
Band-driven cylinders use a band or strip of material wound around a drum to provide linear motion.As the drum rotates, the band moves, causing the load to move along the axis of the cylinder.
Pneumatic Rodless Cylinders:
Pneumatic rodless cylinders use compressed air to move the piston inside the cylinder.They are commonly used in various industrial applications due to their simplicity and cost-effectiveness.
Hydraulic Rodless Cylinders:
Hydraulic rodless cylinders use hydraulic fluid to generate linear motion.These cylinders are known for their high force capabilities and are often used in heavy-duty applications.
Sliding Tube Rodless Cylinders:
This type of rodless cylinder consists of a sliding tube within a fixed outer tube.The sliding tube contains the piston, and as it moves, it generates linear motion.
