About the Airtac SAI50 Standard Cylinder SAI50AX30
The AirTAC SAI50X30 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 30mm stroke. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for short-travel clamping and ejection tasks. The extruded aluminum barrel design omits traditional tie rods while maintaining strict dimensional interchangeability per ISO 15552.
This specific configuration incorporates a SUS420J2 stainless steel piston rod for enhanced corrosion resistance in humid or mildly splash-prone environments. It utilizes PT tapered port threads, and because a magnet is not specified, it operates without integrated magnetic sensing. Adjustable air cushions at both ends ensure smooth deceleration even at operating speeds up to 800 mm/s.

Where the Airtac SAI50 Standard Cylinder SAI50AX30 Is Used
Short-Stroke Clamping
Provides 982 N of holding force at 0.5 MPa for securing workpieces during machining operations within a 30mm travel range.
Package Diverting
Ideal for actuating short-stroke diverters or gating mechanisms on packaging lines where rapid 800 mm/s cycling is required.
Ejection Stations
Delivers quick, compact ejection of finished parts from press beds, utilizing the corrosion-resistant SUS420J2 rod in mild industrial environments.
Is the Airtac SAI50 Standard Cylinder SAI50AX30 the Right Cylinder?
Choose this 50mm bore when an application requires roughly 982 N of push force at 0.5 MPa, bridging the gap between the 40mm bore (628 N) and the 63mm bore (1559 N). The 30mm stroke is optimal for compact, fast-acting sequences where full extension is rarely needed.
Because the standard SAI design relies on pneumatic pressure to maintain position, the rod will drift if air is exhausted or pressure drops. For any setup that must hold a load mechanically during a power loss, consider the SAIL locking variant or an external rod lock. When replacing an existing unit, match the 50mm bore, 30mm stroke, PT G1/4 port, and desired mounting accessory (such as an FA flange or LB foot).
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 SAI50AX30 FAQ
At an operating pressure of 0.5 MPa, the SAI50X30 generates a push force of 982 N and a pull force of 825 N.
Yes, the SAI50X30 is dimensionally interchangeable per ISO 15552, meaning it shares the exact same mounting interface and profile barrel dimensions as other standard ISO 15552 cylinders.
