About the Airtac SAI80 Standard Air Cylinder SAI80X934S
The AirTAC SAI80X934-S is a double-acting ISO 15552 profile cylinder engineered for demanding linear motion tasks. It delivers a robust 2513 N of push force at 0.5 MPa and 3518 N at 0.7 MPa, making it well-suited for heavy material handling. Because this unit features a 934 mm stroke, it is manufactured as a non-standard, made-to-order configuration to meet specialized machinery layouts.
Equipped with a magnetic piston for proximity sensing, this model supports CMSE and DMSE switches via the integrated sensor grooves on both sides of the extruded aluminum barrel. The standard carbon steel piston rod provides excellent tensile strength for industrial loads, while adjustable air cushions at both ends help manage impact deceleration across the long travel distance.

Where the Airtac SAI80 Standard Air Cylinder SAI80X934S Is Used
Extended Stroke Conveying
Drives large pallet pushers or transfer arms across wide machine beds where a 934 mm travel distance is required to bridge production zones.
Heavy Component Ejection
Provides the 2513 N of force needed to eject heavy molded parts or fabricated metal assemblies from hydraulic press beds.
Automated Assembly Transfer
Shifts substantial automotive sub-assemblies between machining stations, using the magnetic piston for precise end-of-stroke confirmation.
Is the Airtac SAI80 Standard Air Cylinder SAI80X934S the Right Cylinder?
When specifying this actuator, verify that the 2513 N thrust at 0.5 MPa is sufficient for your load, or step up to the 100 mm bore if you need 3927 N of push force. Because the 934 mm stroke exceeds standard lengths, the extended rod is highly susceptible to bending under side loads. Always pair this cylinder with an external guide rail or a guided mechanism to prevent premature rod-bearing wear and piston scoring.
This SAI variant uses a G3/8 port and features a magnetic piston (-S) for exact position tracking. It serves as a dimensionally interchangeable drop-in replacement per ISO 15552 interface standards. Note that if your application requires the load to be physically held in place without continuous air pressure, you must use the SAIL (air-released lock) or BSAI (clamp-lock) variant, as standard air cushions only decelerate the piston and do not lock the load.
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 SAI80X934S FAQ
