Asco NNS040/01250000 ISO6431 Standard Pneumatic Cylinder NNS040/012500M0 Seal Repair Kit 40MM Bore 125MM Stroke For Automated Conveyor Line Refurbishment Work

Product Description:

The ASCO Numatics pneumatic cylinder range offers specialized solutions tailored for various industrial applications, including automation systems, cement plant operations, and multi-position filling controls. This diverse portfolio features the NNF 3-position cylinders, which provide independently adjustable strokes ideal for filling and batching tasks. Additionally, the range includes NNS ISO 15552 profile and tie-rod cylinders designed for general industrial automation needs, NSS compact cylinders suited for confined spaces, and NAA cement plant cylinders that are specifically engineered to operate in high-temperature, dust-filled, and vibrating environments.

The cylinder bodies are manufactured from anodized aluminum alloy, enhanced with wear-resistant coatings to ensure durability. Depending on the series, piston rods are constructed from either hard chrome-plated carbon steel or stainless steel grade 1.4571 (AISI 316 Ti). The seals are made from NBR (nitrile rubber) and PUR (polyurethane), materials chosen for their excellent wear resistance and extended service life. Many of the cylinder series support magnetic position detection through either reed or solid-state switches, and they incorporate adjustable pneumatic cushioning at both ends to minimize impact forces and reduce operational noise.

Specifically, the NNF 3-position series is engineered for cement bag filling machines, featuring two independently adjustable stroke lengths—for example, 45 mm plus 15 mm or 30 mm plus 30 mm. This series also offers a trunnion-mount option to enable direct and secure installation. The NAA cement plant cylinder meets ISO 15552 standards and is rated to operate in temperatures ranging from -20°C to +80°C. Its stainless steel construction provides excellent resistance against corrosion caused by cement dust and moisture. The NNS series also complies with ISO 15552 specifications, available in bore sizes ranging from 32 mm to 125 mm and capable of handling a maximum working pressure of 10 bar.

To enhance longevity and minimize downtime, matching repair kits are offered for several models, including the NNF63, NNS040/050, NSS025, and NAA032 cylinders. These kits are designed to facilitate maintenance and ensure continuous reliable operation across different industrial applications.

Features:

The NNF cylinders feature a unique 3-position design that allows independent adjustment of the first and second strokes. This provides precise control over filling and batching processes, enhancing operational accuracy and efficiency.

Designed in accordance with ISO 15552 standards (NNS/NAA series), these cylinders are fully interchangeable with standard cylinders and mounting accessories, ensuring seamless integration into existing systems.

Equipped with piston rods made of hard chrome-plated carbon steel or AISI 316 Ti stainless steel, the cylinders offer excellent corrosion and wear resistance, extending their service life in demanding environments.

The adjustable pneumatic cushioning system minimizes impact, vibration, and noise at both ends of the stroke. This not only protects the cylinder components but also contributes to quieter and smoother operations.

Built-in magnetic pistons enable compatibility with both reed and solid-state switches, facilitating accurate stroke monitoring and feedback for automated control applications.

The NAA series is specifically designed with a stainless steel body and rod, combined with PUR and NBR seals. This construction ensures durability in harsh environments characterized by dust, humidity, and high temperatures, such as those found in cement plants.

A variety of mounting styles are available, including foot, flange, clevis, and trunnion mounts, providing flexibility to suit different installation requirements across the series.

To support maintenance and extend product life, matching seal and wear-part repair kits are offered for models NNF63, NNS040/050, NSS025, and NAA032, enabling efficient and reliable servicing.

The cylinders operate effectively within a broad pressure range of up to 10 bar across most models, accommodating various application demands with consistent performance.

Applications:

The cement industry benefits greatly from the use of NNF 3-position cylinders, which provide precise control over the filling spout positioning. These cylinders also offer multi-stage stroke control, ensuring accurate and efficient cement bag filling processes.

In cement plants, NAA cylinders play a crucial role in managing silo and valve operations. They are used to open and close gates, control conveyor start and stop functions, and actuate groups of valves, thereby optimizing the overall workflow within the plant.

For industrial automation and assembly lines, NNS profile and tie-rod cylinders deliver precise linear motion. These cylinders are integral to maintaining accuracy and consistency across various stages of production.

Packaging machinery relies on both multi-position and standard cylinders to perform tasks such as cartoning, filling, and sealing. Their versatility allows for smooth operation across different packaging stations.

In the realm of material handling, NSS compact cylinders are designed for environments where space is limited. They are effective in clamping, ejecting, and positioning applications, making them ideal for confined workspaces.

Valve automation also utilizes specialized cylinder actuation mechanisms to operate gate valves, butterfly valves, and dampers. This ensures reliable and controlled valve movements across various industrial systems.

Packing and Shipping:

Product Packaging and Shipping for Piston Pneumatic Cylinder

Each piston pneumatic cylinder is carefully packaged to ensure it arrives in perfect condition. The cylinder is first wrapped in a protective plastic film to prevent dust and moisture. It is then securely placed in a custom-fit foam insert to protect against shocks and impacts during transit.

The foam-inserted cylinder is packed inside a sturdy corrugated cardboard box, which is sealed with strong adhesive tape. For bulk orders, multiple units are arranged in larger cartons with additional padding materials to minimize movement and damage.

All packages are clearly labeled with product information, handling instructions, and shipping details. Special care is taken to mark fragile items to ensure careful handling.

We ship our piston pneumatic cylinders via reliable carriers offering tracking services. Depending on the destination, shipping options include standard ground, expedited air freight, or express courier services to meet customer requirements.

Before dispatch, each package undergoes a final quality check to confirm secure packaging and accurate labeling. Our commitment is to deliver your piston pneumatic cylinder safely and promptly.
