About the Airtac SAI50 Standard Cylinder SAI50BX115S
The AirTAC SAI50X115-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 115mm stroke. It delivers a thrust of 982 N at 0.5 MPa, making it well-suited for mid-range automation tasks requiring reliable linear motion.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston (-S) for use with CMSE or DMSE reed switches. The barrel utilizes extruded aluminum with sensor grooves on both sides, and fluid connections use PT tapered threads.

Where the Airtac SAI50 Standard Cylinder SAI50BX115S Is Used
Stainless Rod Actuation
Ideal for packaging machinery where the SUS304 rod material provides necessary corrosion resistance against washdown environments.
Mid-Range Sorting
Provides 982 N of push force at 0.5 MPa to deflect products on automated conveyor sorting lines efficiently.
Sensor-Ready Positioning
The integrated magnet (-S) allows seamless CMSE/DMSE switch mounting in the dual barrel grooves for precise end-of-stroke detection.
Is the Airtac SAI50 Standard Cylinder SAI50BX115S the Right Cylinder?
If an application requires less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa, while moving up to a 63mm bore provides 1559 N. This 115mm stroke falls between standard increments, so verify overall length constraints in your design.
Because this is a double-acting cylinder, it relies on live air pressure to maintain its position. If pneumatic supply is lost or exhausted, the piston will drift; for applications needing fail-safe load holding, consider the SAIL (air-released lock) variant or an external pilot-operated check valve. As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement sharing the identical 50mm bore, 115mm stroke, G1/4 port, and standard mounting accessory footprint.
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.
