About the Airtac SAI50 Standard Cylinder SAI50BX30S
The AirTAC SAI50X30-S is a double-acting ISO 15552 profile cylinder engineered for compact actuation. It provides a push force of 982 N and a pull force of 825 N at 0.5 MPa. The 30 mm stroke is optimal for short-travel clamping and indexing tasks.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in washdown or chemically active environments. It is equipped with a magnet for non-contact position sensing using CMSE or DMSE switches fitted into the extruded aluminum barrel grooves. Fluid ports are PT tapered threads.

Where the Airtac SAI50 Standard Cylinder SAI50BX30S Is Used
Short-Stroke Clamping
Provides 982 N of clamping force at 0.5 MPa for securing machined components during milling or drilling operations.
Package Diverting
The 30 mm stroke rapidly extends a diverter arm to sort packages on a high-speed conveyor line, utilizing the integrated magnet for position confirmation.
Gate Control
Actuates small access gates or machine safety doors in food-processing equipment, relying on the SUS304 rod for corrosion resistance.
Is the Airtac SAI50 Standard Cylinder SAI50BX30S the Right Cylinder?
Choose this 50 mm bore when an application requires roughly 982 N of push force at 0.5 MPa, which sits comfortably between the 40 mm (628 N) and 63 mm (1559 N) alternatives. The short 30 mm stroke minimizes rod overhang, keeping side-load stress on the rod bearing exceptionally low.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops or the valve is centered; the piston will drift. For vertical loads requiring fail-safe holding, select the SAIL pneumatic lock variant or use an external pilot-operated check valve. To replace an existing unit, verify the 50 mm bore, 30 mm stroke, G1/4 port, and ISO 15552 mounting interface dimensions.
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 SAI50BX30S FAQ
At 0.5 MPa, 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 SAI50X30-S is dimensionally interchangeable per ISO 15552. You can directly swap it with other ISO 15552 profile cylinders that share the 50 mm bore, 30 mm stroke, and G1/4 port specifications.
