Why Choose Cylindres sans tige?

Ultimate Space Saving

With no protruding piston rod, the installation length of a rodless cylinder is nearly equal to its effective stroke, significantly saving axial installation space.

Superior Long Stroke Capability

The rodless design prevents piston rod bending and sagging in long-stroke applications, easily achieving linear movements of several meters or even longer.

Versatile Load Guiding

Some rodless cylinders integrate guide units or can be easily combined with external guides, enabling them to handle larger radial loads and moments for smoother motion.

Cylindre sans tige Installation & Maintenance Guide

Conseils d'installation :

Ensure the mounting surface is flat and rigid to provide stable support.
Align carefully to ensure the load’s direction of motion is parallel to the cylinder axis, avoiding extra moments.
Select appropriate mounting accessories and fixing bolts based on load and speed, and ensure they are tightened securely.
Before connecting air tubes, always purge the lines to prevent dust and debris from entering the cylinder.
If using sensors, install and adjust magnetic switches correctly according to the manual.

Entretien courant :

Regularly inspect the cylinder exterior for damage and ensure connections are tight.
For mechanically coupled types, periodically check the tension and wear of sealing bands or steel bands.
Maintain a clean and dry air supply; regularly check the FRL unit, drain water from filters, and replace filter elements as needed.
Observe cylinder operation for smoothness, unusual noises, or speed variations.
Lubricate as necessary (for some models) based on usage frequency and environmental conditions, referring to the product manual.
Avoid overloading, over-stroking, or operating beyond rated parameters.

Always disconnect air and power supplies and release residual system pressure before performing any maintenance to ensure safety.

FAQ sur les raccords pneumatiques

What's the main difference between rodless and standard (rodded) cylinders?

The main differences lie in their structure and resulting characteristics:

Structure: Rodless cylinders have no protruding piston rod; power is transmitted to an external carriage via an opening on the cylinder body or magnetic coupling. Rodded cylinders have a piston rod extending from the cylinder body.
Space Occupancy: Rodless cylinders have an installation length nearly equal to their effective stroke, saving significant space. Rodded cylinders’ total length includes stroke, body length, and extended rod length.
Longueur de la course : Rodless cylinders are ideal for long-stroke applications, as they avoid piston rod bending. Rodded cylinders’ rods can bend or sag on long strokes, requiring extra support.
Load Guiding: Many rodless cylinders have integrated or easily attachable guide mechanisms for better side-load handling.

How do I choose between mechanically coupled and magnetically coupled rodless cylinders?

The choice depends on specific application needs:

Mechanically Coupled (e.g., band type): Generally offer higher load capacity, rigidity, speed, and acceleration. Suitable for most industrial automation. However, their open structure might not be ideal for very dirty or high-cleanliness environments.
Magnetically Coupled: Internal and external pistons are linked by magnetic force, making the cylinder body fully sealed and leak-proof. Excellent for cleanrooms, food/pharma, corrosive environments, or underwater applications. Load capacity and impact resistance are typically lower than mechanical types.

What are key considerations for mounting loads on rodless cylinders?

Loads are mounted directly on the external carriage. Key considerations include:
- Alignment: Ensure the load’s center of gravity is as close as possible to the carriage center and aligned with the direction of motion to minimize off-center loads and moments.
- Load Magnitude: Do not exceed the maximum allowable load and moments specified in the cylinder catalog.
- External Guiding: If the load is large or significant side forces/moments are present, additional external linear guides may be needed to support and guide the load, protecting the cylinder and ensuring motion accuracy, even if the cylinder has internal guiding.
- Connection: The connection between the load and the carriage must be secure and rigid to prevent loosening.
Improper load mounting can severely affect the performance and lifespan of rodless cylinders.

What stroke accuracy can rodless cylinders achieve, and what affects it?

The stroke accuracy (or repeat positioning accuracy) of rodless cylinders varies by type, brand, and specific model. Generally, high-quality rodless cylinders can achieve good accuracy levels, for example, ±0.1mm to ±0.5mm or better.

Key factors affecting stroke accuracy include:

Cylinder Manufacturing Precision: Including guide rail straightness, carriage-to-guide clearance, seal friction consistency, etc.
Load Conditions: The magnitude, direction, and eccentricity of the load affect forces on the carriage and thus positioning.
Installation Accuracy: Flatness of the mounting surface, alignment of the cylinder with the motion mechanism.
Control System: Valve response speed, PLC control logic, sensor accuracy and response.
Air Pressure Fluctuations: Unstable air pressure causes output force variations, affecting positioning.
Operating Speed and Acceleration: High speeds or high acceleration/deceleration pose greater challenges to accuracy.
Température ambiante : Temperature changes can cause material expansion/contraction, affecting precision.

For high-precision applications, it’s advisable to choose rodless cylinders with high-performance guide units, paired with precise control systems and sensors.

Can rodless cylinders be used in vertical installations? What are the precautions?

Yes, many rodless cylinders can be installed vertically, but special attention is required:

Load Direction & Self-Weight: In vertical mounting, gravity constantly acts on the load. Ensure the cylinder’s output force (when lifting) or holding force (when static or moving downwards) can overcome the load’s weight with sufficient margin.
Freinage et prévention des chutes : For vertical lifting, especially with heavy loads or safety risks, additional braking devices or fall-arrest mechanisms are crucial. Relying solely on air pressure to hold the load is unsafe, as air loss or system failure could cause the load to drop.
Guiding & Stability: Load stability is more critical in vertical motion. Ensure the cylinder’s guiding system can withstand side forces or moments due to gravity.
Amortissement : Reliable end-of-stroke cushioning is essential to absorb the impact energy of the load stopping in vertical motion.
Limitations of Magnetically Coupled Types: For magnetically coupled rodless cylinders, pay close attention to their maximum holding force in vertical installations to prevent decoupling due to excessive load.
Select Appropriate Model: Consult the manufacturer to confirm if the chosen model is suitable for vertical installation and to understand its specific performance parameters and limitations in such applications.

Safety is paramount when installing rodless cylinders vertically; always implement adequate protective measures.
