About the Airtac SAI80 Standard Air Cylinder SAI80X50S
The AirTAC SAI80X50-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 50mm stroke. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it well-suited for short-travel, high-thrust automation tasks. The extruded aluminum barrel design eliminates protruding tie rods while maintaining strict dimensional interchangeability with standard ISO 15552 mounting interfaces.
This specific configuration includes a magnet (-S) for proximity sensing, allowing seamless integration with CMSE or DMSE series reed switches via the dual sensor grooves on the barrel. It is built with a standard carbon steel piston rod and utilizes adjustable air cushions at both ends to decelerate the piston effectively over its short 50mm travel. For environments exceeding standard temperature ranges, Viton (H) seals are available as an alternative to the standard TPU elastomers.

Where the Airtac SAI80 Standard Air Cylinder SAI80X50S Is Used
Short-Stroke Pressing
Ideal for small stamping or press-fitting operations where a brief 50mm travel and 2513 N of thrust are required to seat components securely.
Heavy-Duty Ejection
Provides the robust force needed to push heavy finished parts or pallets off a conveyor line quickly within a confined machinery footprint.
Pallet Stopper
Acts as a high-force pneumatic stop mechanism for medium-sized pallets in material handling systems, utilizing its short stroke to block and release loads on demand.
Is the Airtac SAI80 Standard Air Cylinder SAI80X50S the Right Cylinder?
Choose this 80mm bore when an application demands significantly more force than a 63mm cylinder (which provides 1559 N at 0.5 MPa) but does not require the massive footprint of a 100mm unit (3927 N). The 50mm stroke is optimal for compact pressing, clamping, or ejecting operations where space is restricted but high power is necessary.
Because the standard SAI is double-acting, it relies entirely on continuous air pressure to maintain its position. If power or air supply is lost, the piston will drift; for applications requiring fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. When replacing existing actuators, ensure the ISO 15552 dimensions match your current mounting hardware, utilize the G3/8 PT port connections, and select appropriate FA/FB flanges or TC trunnion brackets.
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 SAI80X50S FAQ
At 0.5 MPa operating pressure, the SAI80X50-S generates a push force of 2513 N and a pull force of 2268 N. If pressure is increased to 0.7 MPa, the push force reaches 3518 N.
Yes, the SAI80X50-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are standardized. It serves as a drop-in replacement for other ISO 15552 cylinders, provided you match the 80mm bore, 50mm stroke, and G3/8 port size.
