About the Airtac SAI80 Standard Air Cylinder SAI80X425S
The AirTAC SAI80X425-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust push force of 2513 N and pull force of 2268 N at 0.5 MPa, this 80 mm bore unit handles substantial loads across its 425 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a magnet for position sensing, allowing seamless integration with CMSE or DMSE reed switches along the dual sensor grooves machined into both sides of the barrel. It utilizes standard carbon steel piston rod material and features adjustable air cushions at both ends to absorb kinetic energy. Operating efficiently at speeds between 30 and 800 mm/s, it is a versatile choice for demanding pneumatic systems.

Where the Airtac SAI80 Standard Air Cylinder SAI80X425S Is Used
Heavy Material Lift
Provides the 2513 N push force needed to elevate heavy material lifts or pallet stacks over a 425 mm vertical travel distance.
Pallet Diversion
Extends robustly to divert heavy pallets on a conveyor line, utilizing the integrated magnet to confirm extension and retraction.
Press Ejection
Ejects dense finished parts from a hydraulic press, relying on adjustable air cushions to decelerate the rod smoothly at stroke end.
Is the Airtac SAI80 Standard Air Cylinder SAI80X425S the Right Cylinder?
Selecting this 80 mm bore over a smaller 63 mm option provides a significant force upgrade, jumping from 1559 N to 2513 N at 0.5 MPa. If your application requires less force, stepping down to the 63 mm bore saves space and air consumption. Because this model features a 425 mm stroke, the extended carbon steel rod is susceptible to bending under side loads; utilize an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
This model is dimensionally interchangeable per ISO 15552, ensuring a seamless drop-in replacement for other standard profile cylinders with identical 80 mm bore, 425 mm stroke, G3/8 PT ports, and standard mounting accessories. Note that a standard SAI cylinder relies on continuous air pressure to maintain its position; if the air is exhausted, the load will drift. For applications requiring dead-end holding without live pressure, consider the SAIL (lock) or BSAI (clamp-lock) variants.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI80 Standard Air Cylinder SAI80X425S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. If operating at 0.7 MPa, the push force increases to 3518 N.
No, a standard double-acting SAI cylinder will drift or drop if air pressure is lost. The adjustable air cushion only decelerates the piston near the end of the stroke and does not act as a brake. For dead-end holding, use the SAIL or BSAI variant.
