About the Airtac SAI50 Standard Cylinder SAI50BX35S
The AirTAC SAI50X35-S is a double-acting ISO 15552 profile cylinder engineered for compact linear motion. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for short-stroke clamping and ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable per ISO 15552 standards.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance in wet or chemically exposed environments. It is equipped with a magnetic piston (-S) for seamless integration with CMSE or DMSE sensor switches along the dual grooves on the barrel, and utilizes PT tapered port threads.

Where the Airtac SAI50 Standard Cylinder SAI50BX35S Is Used
Short-Stroke Clamping
Ideal for holding metal or plastic components securely in place during machining, drilling, or welding operations.
Product Ejection
Provides rapid, forceful ejection of finished parts from conveyor lines or press dies using its 982 N push force.
Packaging Diversion
Executes quick diverting and sorting movements on packaging lines where a short, fast stroke is required.
Is the Airtac SAI50 Standard Cylinder SAI50BX35S the Right Cylinder?
Select this 50 mm bore when an application demands more power than the 40 mm version (628 N push at 0.5 MPa) but has spatial constraints requiring a very short 35 mm stroke. If your setup needs to hold a load vertically or resist drift during a complete air-loss event, the standard adjustable air cushions will not act as a lock. In such cases, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To replace an existing unit, match the 50 mm bore, 35 mm stroke, PT G1/4 port, and mounting accessory (like an FA flange), and ensure the -S magnet is included for sensor feedback.
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 SAI50 Standard Cylinder SAI50BX35S FAQ
At a standard operating pressure of 0.5 MPa, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X35-S is dimensionally interchangeable per ISO 15552 profile cylinder standards. You can drop it into existing setups by matching the 50 mm bore, 35 mm stroke, and G1/4 port size.
