About the Airtac SAI50 Standard Cylinder SAI50X70
The AirTAC SAI50X70 is a double-acting ISO 15552 profile cylinder built with a 50mm bore and 70mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it a solid choice for medium-duty handling tasks.
This model features a standard carbon steel piston rod and a tapered PT G1/4 port. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAI50 Standard Cylinder SAI50X70 Is Used
Package Diversion
Provides the precise 982N push force needed to actuate diverter arms on high-speed packaging conveyors.
Component Clamping
Holds medium-sized aluminum or plastic workpieces securely in place during light machining and assembly.
Pallet Stops
Acts as a reliable stop gate for pallets accumulating on roller conveyors in material handling zones.
Is the Airtac SAI50 Standard Cylinder SAI50X70 the Right Cylinder?
Select this 50mm bore when a 40mm bore (628N push at 0.5 MPa) is too weak, but you want to avoid the larger footprint of a 63mm cylinder (1559N). The 70mm stroke is ideal for short, rapid movements operating within the 30-800 mm/s speed range.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops. For vertical loads requiring fail-safe holding, consider the SAIL pneumatic lock variant or use an external rod lock. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard 50mm bore, 70mm stroke ISO 15552 unit with a G1/4 port and standard mounting accessories like FA flanges.
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 SAI50X70 FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
Yes. The SAI50X70 is a genuine ISO 15552 profile cylinder, meaning it is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, serving as a direct replacement.
