About the Airtac SAI50 Standard Cylinder SAI50BX95
The AirTAC SAI50X95 is a double-acting ISO 15552 profile cylinder offering a 982 N push force at 0.5 MPa. Its 95 mm stroke is well-suited for mid-range automation tasks requiring reliable linear motion. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies sensor placement and maintenance.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in washdown or chemically aggressive settings. It utilizes PT tapered port threads and is built without a magnet. For operations needing end-of-stroke locking, the SAIL variant provides an air-released brake to hold loads securely without continuous pressure.

Where the Airtac SAI50 Standard Cylinder SAI50BX95 Is Used
Stainless Clamping
Ideal for food-grade or medical packaging lines where the SUS304 rod resists moisture and cleaning agents during part clamping.
Mid-Range Diverting
Provides the 982 N force needed to push medium-weight products across sorting lanes on high-speed material handling systems.
Compact Ejection
The 95 mm stroke delivers rapid ejection of molded components from small to medium presses without excessive cycle times.
Is the Airtac SAI50 Standard Cylinder SAI50BX95 the Right Cylinder?
Selecting this 50 mm bore makes sense when a 40 mm cylinder (providing 628 N at 0.5 MPa) lacks the necessary thrust, but a larger 63 mm unit (delivering 1559 N) would be physically oversized. The 95 mm stroke provides ample travel for compact clamping and lifting stations. Because this is a standard double-acting actuator, it cannot maintain position if air pressure drops; utilize the SAIL locking version if your fixture requires dead-stop holding.
To match this exact ISO 15552 replacement, specify a 50 mm bore, 95 mm stroke, PT G1/4 port, and the absence of a magnet (-S). Mounting can be achieved using FA flanges or LB foot brackets. The standard adjustable air cushions at both ends ensure smooth deceleration of the 50 mm piston across its 30-800 mm/s operating range.
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 SAI50BX95 FAQ
At 0.5 MPa, it provides 982 N of push force and 825 N of pull force. If your application requires higher thrust, stepping up to the 63 mm bore yields 1559 N at the same pressure.
Yes, the SAI50X95 adheres to ISO 15552 mounting dimensions, allowing it to serve as a direct replacement for other profile cylinders with matching 50 mm bore and 95 mm stroke specifications.
