About the Airtac SAI50 Standard Cylinder SAI50BX5
The AirTAC SAI50X5 is a double-acting ISO 15552 profile cylinder engineered for ultra-short actuation. Delivering a push force of 982 N at 0.5 MPa, this 50 mm bore unit is tailored for high-impact duties requiring minimal travel. The 5 mm stroke excels in rapid clamping and ejection cycles. Its extruded aluminum barrel omits tie rods, presenting a clean, standardized exterior.
This specific configuration features a SUS304 stainless steel rod, providing superior corrosion resistance for harsh or washdown environments. It utilizes PT tapered port threading and is built without a magnet. The barrel incorporates dual-sided sensor grooves, allowing flexible mounting of switches if a magnet-equipped variant is adopted later.

Where the Airtac SAI50 Standard Cylinder SAI50BX5 Is Used
High-Force Ejection
Uses the 982 N push force to rapidly eject finished parts from molds or dies within a tight 5 mm space.
Short-Stroke Clamping
Ideal for securing heavy workpieces during machining, leveraging the robust 50 mm bore for rigid holding.
Compact Stopping
Serves as a heavy-duty stopper in automated lines where a short, solid physical barrier is required.
Is the Airtac SAI50 Standard Cylinder SAI50BX5 the Right Cylinder?
Choose this 50 mm bore when a 40 mm bore (628 N at 0.5 MPa) lacks the necessary push strength for your short-journey task. If your application requires even greater force, stepping up to the 63 mm bore yields 1559 N. Because the 5 mm stroke is extremely short, side-load bending is negligible, though precise rod alignment remains vital to prevent premature seal wear.
As a standard double-acting actuator, this cylinder will drift if air pressure is lost. It cannot hold a load mid-stroke without live pressure; for fail-safe holding, consider the SAIL variant with an air-released lock. This model is dimensionally interchangeable per ISO 15552, featuring a G1/4 port, and supports mounting accessories like FA flanges or TC trunnions.
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.
