About the Airtac SAI80 Standard Air Cylinder SAI80X70
The AirTAC SAI80X70 is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force at 0.5 MPa. Its 70 mm stroke provides rapid, short-travel actuation for heavy-duty machinery. The extruded aluminum barrel eliminates tie rods, presenting a clean profile that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration features a standard carbon steel piston rod and PT (tapered) G3/8 port threads. Because a magnet is not specified, it ships without one; add the -S suffix if you require CMSE or DMSE sensor detection via the dual grooves on the barrel.

Where the Airtac SAI80 Standard Air Cylinder SAI80X70 Is Used
Stamping Press Feed
Provides the robust 2513 N push force needed to feed heavy gauge sheet metal into a stamping press with a precise 70 mm travel.
Pallet Diverter
Short 70 mm stroke quickly diverts heavy pallets between parallel conveyor lines without encroaching on the main transport lane.
Component Press Fit
Delivers consistent downward force to seat industrial bearings and bushings into housings on an automated assembly line.
Is the Airtac SAI80 Standard Air Cylinder SAI80X70 the Right Cylinder?
An 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, striking a strong balance for mid-weight handling. If your application requires less force, stepping down to the 63 mm bore yields 1559 N, which may improve cycle times and reduce air consumption. For higher demands, the 100 mm bore provides 3927 N.
Since this is a standard SAI variant, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. For vertical loads requiring safety locking, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant. To match this cylinder: 80 mm bore, 70 mm stroke, G3/8 port, PT thread, and your required mounting accessory (e.g., TC trunnion 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 SAI80 Standard Air Cylinder SAI80X70 FAQ
At 0.5 MPa, the SAI80X70 provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
Yes. The SAI80X70 is a profile-type ISO 15552 cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders. It uses a G3/8 port and is not a tie-rod design.
