Product Description:
The ASCO Numatics pneumatic cylinder range offers a variety of specialized solutions tailored for industrial automation, cement plant applications, and multi-position filling control processes. This extensive portfolio includes the NNF 3-position cylinders, which feature independently adjustable strokes specifically designed for filling and batching tasks. Additionally, it offers the NNS ISO 15552 profile and tie-rod cylinders suited for general industrial automation needs, the NSS compact cylinders ideal for installations with limited space, and the NAA cement plant cylinders built to withstand harsh environments characterized by high temperatures, dust, and vibration.
All cylinder bodies are crafted from anodized aluminum alloy and enhanced with wear-resistant coatings to ensure durability. The piston rods are manufactured using either hard chrome-plated carbon steel or stainless steel grade 1.4571 (AISI 316 Ti), depending on the specific series. To maintain longevity and resist wear, the seals are made from NBR (nitrile rubber) and PUR (polyurethane). Most cylinder models incorporate magnetic position detection systems utilizing either reed or solid-state switches. Furthermore, adjustable pneumatic cushioning is integrated at both ends of the cylinders to minimize impact forces and reduce noise during operation.
The NNF 3-position series is engineered specifically for cement bag filling machines. It features two independently adjustable stroke lengths—for example, configurations like 45 mm plus 15 mm or two equal 30 mm strokes—allowing for precise control. A trunnion-mount option is also available, enabling easy and direct adaptation to existing equipment. Meanwhile, the NAA cement plant cylinders comply with ISO 15552 standards and operate effectively within a temperature range of -20°C to +80°C. Their stainless steel construction provides excellent resistance against corrosion caused by cement dust and moisture.
The NNS series adheres to the ISO 15552 standard and comes in bore sizes ranging from 32 mm to 125 mm, supporting a maximum working pressure of 10 bar. To enhance operational reliability and reduce downtime, matching repair kits are offered for several models, including the NNF63, NNS040/050, NSS025, and NAA032. These kits help extend the service life of the cylinders and ensure efficient maintenance procedures.
Features:
The NNF series features a 3-position design, allowing for independently adjustable first and second strokes. This design provides precise control over filling and batching processes, enhancing accuracy and efficiency.
Compliant with ISO 15552 standards, the NNS and NAA models are fully interchangeable with standard cylinders and mounting accessories. This ensures compatibility and ease of integration into existing systems.
Constructed with stainless steel piston rods, these components are available in hard chrome-plated carbon steel or AISI 316 Ti. This choice of materials offers excellent resistance to corrosion and wear, extending the service life of the cylinders.
The cylinders are equipped with adjustable pneumatic cushioning on both ends. This feature significantly reduces the impact, vibration, and noise at the end of the stroke, contributing to smoother operation and longer component life.
For precise stroke monitoring, magnetic position sensing is incorporated through a built-in magnetic piston. This design is compatible with both reed and solid-state switches, enabling reliable detection of piston position.
Specifically designed for demanding environments like cement plants, the NAA series boasts a stainless steel body and rod, along with PUR/NBR seals. These materials are rated to withstand dusty, humid, and high-temperature conditions.
A variety of mounting options are available across the series, including foot, flange, clevis, and trunnion mounts. This versatility allows for flexible installation to suit different application requirements.
To facilitate maintenance and repair, dedicated repair kits are offered. These kits include matching seals and wear parts compatible with models such as NNF63, NNS040/050, NSS025, and NAA032.
Most series operate reliably under a wide pressure range, with an operating pressure capability of up to 10 bar. This range supports various industrial applications with differing pressure requirements.

Applications:
Cement bag filling machines utilize NNF 3-position cylinders to achieve precise positioning of filling spouts. These cylinders also offer multi-stage stroke control, ensuring accurate and efficient filling operations.
In cement plants, silo and valve control is managed by NAA cylinders. These cylinders are responsible for the opening and closing of gates, starting and stopping conveyors, as well as actuating groups of valves to maintain smooth plant operations.
For industrial automation and assembly processes, NNS profile and tie-rod cylinders are employed. These cylinders provide reliable and precise linear motion, which is essential for production line accuracy and efficiency.
Packaging machinery benefits from the use of both multi-position and standard cylinders. These cylinders support various packaging tasks, including cartoning, filling, and sealing stations, ensuring consistent and high-quality packaging output.
In material handling applications, NSS compact cylinders are favored for their space-saving design. They are ideal for clamping, ejecting, and positioning tasks where installation space is limited but performance cannot be compromised.
Valve automation relies on cylinder actuation to control gate valves, butterfly valves, and dampers. This application ensures precise and reliable valve movement for effective process control across various industries.
