About the Airtac SAI50 Standard Cylinder SAI50BX40S
The AirTAC SAI50X40-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke automation. Delivering a push force of 982 N at 0.5 MPa, it fits perfectly into compact assemblies requiring rapid, high-impact actuation.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual barrel grooves. It features PT tapered port threads and adjustable air cushions at both ends to manage end-of-stroke impact.

Where the Airtac SAI50 Standard Cylinder SAI50BX40S Is Used
Short-Stroke Clamping
Ideal for securing workpieces in machining fixtures where a brief 40 mm travel and 982 N force are required.
Package Ejector
Provides rapid, repetitive ejection of goods from conveyor lines using its magnetic piston for position confirmation.
Corrosive Environment Actuation
The SUS304 stainless steel rod makes it suitable for food packaging or light washdown environments.
Is the Airtac SAI50 Standard Cylinder SAI50BX40S the Right Cylinder?
Choose this 50 mm bore when a 32 mm cylinder lacks thrust (offering only 402 N at 0.5 MPa) but a 63 mm unit is physically too large. The 40 mm stroke is optimal for brief clamping or ejecting tasks.
Because this standard cylinder is double-acting, it will drift if air pressure is lost; use a SAIL variant if your workflow demands mechanical load holding. As a genuine ISO 15552 profile barrel cylinder, it drops in seamlessly for machines requiring a 50 mm bore, 40 mm stroke, PT port, and standard mounting accessories like FA or LB.
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 SAI50BX40S FAQ
At 0.5 MPa operating pressure, 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 -S suffix indicates this model includes a magnet. It is fully compatible with CMSE and DMSE sensor switches mounted in the extruded aluminum barrel grooves.
