Product Description:
The ASCO Numatics pneumatic cylinder range offers a variety of specialized solutions designed to meet the needs of industrial automation, cement plant operations, and multi-position filling control systems. This extensive portfolio features different types of cylinders tailored for specific applications, including the NNF 3-position cylinders with independently adjustable strokes optimized for filling and batching processes, the NNS ISO 15552 profile and tie-rod cylinders for general industrial automation tasks, compact NSS cylinders suited for installations with limited space, and the robust NAA cement plant cylinders engineered to withstand harsh conditions such as high temperatures, dust, and vibrations.
The construction of these cylinders reflects their industrial robustness. Cylinder bodies are made from anodized aluminum alloy, enhanced with wear-resistant coatings to ensure durability. For the piston rods, materials vary according to the series, with options including hard chrome-plated carbon steel or stainless steel 1.4571 (AISI 316 Ti), which offer excellent resistance to wear and corrosion. The sealing components are made from NBR (nitrile rubber) and PUR (polyurethane), chosen for their durability and capacity to prolong service life. Additionally, most series come equipped to support magnetic position detection through either reed switches or solid-state switches. Pneumatic cushioning is adjustable at both ends of the cylinders, helping to minimize impact forces and noise during operation.
The NNF 3-position cylinder series is specially designed for cement bag filling machinery, featuring two independently adjustable strokes — for example, combinations like 45 mm plus 15 mm or 30 mm plus 30 mm — which allow for precise control of the filling process. A trunnion-mount option is also available to enable direct fitting. The NAA cement plant cylinder conforms to ISO 15552 standards and is rated for operation within a temperature range from -20°C to +80°C. It incorporates stainless steel construction to provide corrosion resistance against harsh cement dust and moisture exposure. Meanwhile, the NNS series also complies with ISO 15552, offering bore sizes from 32 mm up to 125 mm and a maximum working pressure of 10 bar.
To support ongoing maintenance and ensure operational longevity, matching repair kits are available for selected models, including the NNF63, NNS040/050, NSS025, and NAA032 cylinders. These kits help extend service life and minimize downtime by enabling quick and effective repairs.
Features:
The NNF series features a unique 3-position design that allows independent adjustment of the first and second strokes. This provides precise control over filling and batching processes, ensuring accuracy and efficiency in operation.
Compliant with ISO 15552 standards, models such as NNS and NAA are fully interchangeable with standard cylinders and their corresponding mounting accessories. This compatibility simplifies maintenance and integration into existing systems.
The piston rods are manufactured from stainless steel options, including hard chrome-plated carbon steel or AISI 316 Ti. These materials offer excellent resistance to corrosion and wear, extending the service life of the components.
Adjustable pneumatic cushioning is incorporated at both ends of the stroke to minimize impact, vibration, and noise. This feature enhances the smoothness of operation and reduces mechanical stress on the equipment.
For stroke monitoring, the cylinders include built-in magnetic pistons that are compatible with both reed and solid-state switches. This magnetic position sensing allows for reliable and accurate detection of piston position.
Designed for demanding environments such as cement plants, the NAA variant boasts a stainless steel body and rod combined with PUR/NBR seals. It is specially rated to withstand dusty, humid, and high-temperature conditions, ensuring durability under harsh industrial settings.
The cylinders offer versatile mounting options including foot, flange, clevis, and trunnion types across the series. This flexibility facilitates easy installation tailored to various application requirements.
For maintenance convenience, repair kits containing matching seals and wear parts are available for multiple models including NNF63, NNS040/050, NSS025, and NAA032. This helps in minimizing downtime and maintaining optimal performance.
Most series are designed to operate within a wide pressure range, accommodating up to 10 bar. This wide operating pressure capacity ensures adaptability to different pneumatic system requirements.

Applications:
Cement bag filling machines utilize NNF 3-position cylinders, which provide precise positioning of the filling spout. These cylinders also support multi-stage stroke control, ensuring accurate and efficient filling processes.
In cement plants, NAA cylinders play a crucial role in controlling silos and valves. They are responsible for opening and closing gates, starting and stopping conveyors, and actuating valve groups to maintain smooth plant operations.
For industrial automation and assembly lines, NNS profile and tie-rod cylinders offer precise linear motion. These cylinders help achieve accuracy and reliability during production, optimizing assembly processes.
Packaging machinery benefits from both multi-position and standard cylinders. These are commonly used in cartoning, filling, and sealing stations to enhance the efficiency and consistency of packaging tasks.
In the field of material handling, NSS compact cylinders are ideal for environments with limited space. They are designed for clamping, ejecting, and positioning tasks where compactness and performance are essential.
Valve automation systems rely on cylinder actuation for various types of valves, including gate valves, butterfly valves, and dampers. This ensures precise control and reliable operation of the valves in different industrial applications.
