About the Airtac SAI50 Standard Cylinder SAI50BX15S
The AirTAC SAI50X15-S is a double-acting ISO 15552 profile cylinder engineered for exacting short-stroke tasks. Delivering a push force of 982 N at 0.5 MPa, it provides robust actuation in tight spaces. The 15 mm stroke is optimal for clamping, ejection, or brief gating movements.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in washdown or chemically active environments. Equipped with a magnet for proximity sensing, it integrates seamlessly with CMSE and DMSE switches housed in the barrel's dual sensor grooves. PT threaded ports ensure a secure, tapered pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50BX15S Is Used
Short-Stroke Clamping
Provides 982 N of clamping force at 0.5 MPa for securing workpieces during machining or assembly operations within a 15 mm travel envelope.
Product Diverting
Acts as a high-speed diverter or gate for lightweight packaging lines, utilizing the integrated magnet and CMSE sensors for precise end-position confirmation.
Washdown Ejection
The SUS304 stainless steel rod excels in food processing or chemical washdown environments, safely ejecting finished parts despite moisture exposure.
Is the Airtac SAI50 Standard Cylinder SAI50BX15S the Right Cylinder?
Choose this 50 mm bore actuator when a 40 mm bore (628 N at 0.5 MPa) lacks thrust, but a 63 mm bore (1559 N) would be physically oversized. The 15 mm stroke minimizes cycle time and mechanical envelope. For applications requiring position holding without sustained air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) variant, as standard air cushions only decelerate the piston at stroke end and do not prevent drift. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders, matching the 50 mm bore, 15 mm stroke, G1/4 port, and standard mounting accessories.
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.
