About the Airtac SAI100 Standard Air Cylinder SAI100BX500S
The AirTAC SAI100X500-S is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 3927 N of push force at 0.5 MPa. Its extruded aluminum barrel omits tie rods for a clean exterior, while the 500 mm stroke provides substantial linear travel for heavy-duty automation. This genuine AirTAC unit is dimensionally interchangeable with other ISO 15552 cylinders, offering a direct drop-in replacement for standardized mounting footprints.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or chemically active settings. Equipped with a magnet (-S), the barrel features dual-sided sensor grooves that accept CMSE and DMSE switches for precise end-of-stroke detection. Fluid ports feature PT tapered threading, and the standard TPU seals accommodate operating pressures up to 1.0 MPa.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX500S Is Used
Heavy Stamping Press
Provides the high 5497 N push force at 0.7 MPa needed to actuate heavy stamping and forming presses, while the 500 mm stroke accommodates deep-draw tooling clearance.
Large Mold Handling
Ideal for pushing or ejecting large injection molds, utilizing the SUS304 stainless steel rod to prevent rust formation in humid factory environments.
Pallet Lift Station
Drives heavy pallet lifting stations where the dual sensor grooves and integrated magnet allow precise positioning feedback for automated material handling.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX500S the Right Cylinder?
With a 100 mm bore generating 3927 N of push force at 0.5 MPa (and 5497 N at 0.7 MPa), this model is ideal for high-thrust operations. If an application requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. For this 500 mm stroke, the unsupported piston rod is highly susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure is lost or exhausted—the piston will drift. If the machinery requires position holding without live pressure, consider the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock. For replacement matching, verify the 100 mm bore, 500 mm stroke, G1/2 port, PT thread, and required mounting accessories (such as FA flange or TC trunnion).
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 SAI100 Standard Air Cylinder SAI100BX500S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X500-S is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders. Always verify the G1/2 port size and 500 mm stroke match your existing fixture.
