OEM Factory ISO15552 Standard Pneumatic Cylinder DNC Series Double Acting Hard Aluminum Piston Rod Cylinders Wholesale Manufacturer
- Overview
- Recommended Products
- IS015552 and VDMA24562 standard cylinder;
- The piston seal is composed of two Y-shape one-way seal structure, which has compensation function,long service life and low start-up pressure;
- The square aluminum pipe without tie rod has good corrosion resistance;
- The buffer adjustment of cylinder is smooth and steady;
- Cylinders and accessories for installation with several specifications are optional.
- Precision manufacturing to ISO 15552 / VDMA 24562. Every DNC cylinder is machined on CNC centers with bore tolerances held to exacting standards. The result is consistent sealing, repeatable stroke accuracy, and low friction across the full product lifecycle.
- Proprietary Y-type dual-seal piston design. Unlike conventional O-ring single-seal pistons, our two-piece Y-seal structure provides dynamic compensation as seals wear. This yields measurably lower breakaway pressure, longer maintenance intervals, and smoother stroke initiation — especially critical in low-pressure circuits or vertical-load applications.
- Tie-rod-free extruded aluminum profile. The square barrel is precision-extruded from aluminum alloy with integrated sensor slots. Eliminating external tie rods reduces weight by up to 15% versus traditional tie-rod designs, simplifies cleaning (no crevices for debris), and provides superior corrosion resistance in washdown or humid environments.
- Fully adjustable pneumatic cushioning. Both end caps feature needle-valve adjustable air cushions. This allows fine-tuning of deceleration behavior for specific loads, reducing end-of-stroke impact noise and extending seal life. The wide cushion adjustment range handles loads from light instrument actuation to heavy pressing.
- Direct FESTO / SMC interchangeability. Mounting hole patterns, port locations, rod-end threads, and accessory interfaces are dimensionally identical to FESTO DNC and SMC equivalent series. No adapter plates or re-drilling required — swap and run.
- Wide accessory ecosystem. Full compatibility with ISO-standard mounting accessories: foot brackets (LB), front/rear flanges (FA/FB), center trunnion (CR), swivel flanges, clevis forks, rod-end spherical joints, and proximity sensor brackets. One cylinder series covers all mounting scenarios.
- Magnetic piston as standard. Every DNC cylinder ships with an integrated magnetic ring, enabling external position sensing via reed or solid-state proximity switches without opening the cylinder or modifying the piston.
- Competitive total cost of ownership. Factory-direct pricing with no minimum order quantity combines with extended service intervals and swappable seal kits to deliver the lowest per-cycle cost in its class. Typical ROI versus OEM-brand equivalents: 30–50% savings with no compromise on performance.

Product Advantages
Why choose AIRWORK DNC Series over generic standard cylinders:
Installation and application
1. When load changes in the work, the cylinder with abundant output capacity shall be selected.
2. Relative cylinder with high temperature resistance or corrosion resistance shall be chosen under the condition of high temperature or corrosion.
3. Necessary protection measure shall be taken in the environment with higher humidity, much dust or water drops, oil dust and welding dregs.
4. Dirty substances in the pipe must be eliminated before cylinder is connected with pipeline to prevent the entrance of particles into the cylinder.
5.The medium used by cylinder shall be filtered to 40 u m or below.
6. Anti-freezing measure shall be adopted under low temperature environment to prevent moisture freezing.
7. The cylinder shall be carried out test run without load before application. Prior to run, buffer shall be turned to minimum and gradually released to avoid the damage on cylinder caused by excessive impact.
8. The cylinder shall avoid the influence of side load in operation to maintain the normal work of cylinder and extend the service life.
9.If the cylinder is dismantled and stored for a long time, please conduct anti-rust treatment to the surface. Anti-dust caps shall be added in air inlet and outlet ports.
