About the Airtac SAI50 Standard Cylinder SAI50BX55S
The AirTAC SAI50X55-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 55 mm stroke is optimal for short-travel clamping and ejection tasks. The extruded aluminum barrel omits tie-rods, providing a clean exterior that simplifies mounting and cleaning.
This configuration includes a -S magnet for direct integration with CMSE or DMSE reed switches via the dual sensor grooves. It is built with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads to ensure a reliable pneumatic seal.

Where the Airtac SAI50 Standard Cylinder SAI50BX55S Is Used
Short-Stroke Clamping
Ideal for holding metal workpieces securely in machining fixtures using its 982 N thrust.
Package Ejection
Provides rapid, forceful ejection of finished goods from conveyor lines within a compact footprint.
Material Forming
Executes light stamping and bending operations where a corrosion-resistant SUS304 rod is advantageous.
Is the Airtac SAI50 Standard Cylinder SAI50BX55S the Right Cylinder?
Select this 50 mm bore when an application requires more power than a 40 mm bore (which provides 628 N at 0.5 MPa) but lacks the physical space for a 63 mm unit. The 55 mm stroke provides rapid, compact actuation without the side-load risks associated with longer extensions. Because the standard SAI is double-acting, it will drift if air pressure is lost; use a SAIL variant if the system requires pneumatic locking. For ISO 15552 direct replacements, match the 50 mm bore, 55 mm stroke, PT G1/4 ports, and appropriate mounting accessories like an FA flange.
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 SAI50BX55S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force.
Yes, the -S suffix indicates an integrated magnet, allowing CMSE or DMSE switches to track piston position using the barrel's dual sensor grooves.
