About the Airtac SAI125 Standard Air Cylinder SAI125X930SN
The AirTAC SAI125X930-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 6136 N of push force at 0.5 MPa, it easily manages substantial payloads. Because the 930 mm stroke exceeds the standard 1500 mm maximum for this bore, it is produced as a non-standard, made-to-order unit to match your exact linear motion requirements.
This variant features a standard carbon steel piston rod and durable NBR seals, ensuring reliable sealing for general industrial pneumatics. Equipped with a magnet (-S), the extruded aluminum barrel integrates dual-side sensor grooves designed specifically for CMSE and DMSE reed switches, providing precise end-of-stroke position detection across the extended travel distance.

Where the Airtac SAI125 Standard Air Cylinder SAI125X930SN Is Used
Large Press Feeders
Drives heavy material feeding mechanisms over a 930 mm span, utilizing the 6136 N push force to move substantial metal stock into forming presses.
Pallet Handling
Indexes large palletized goods across extended conveyor lengths, relying on the integrated magnet for precise sensor feedback at both stroke ends.
Automated Stacking
Actuates stacking arms in automated packaging lines, where the long 930 mm travel accommodates varying product heights without repositioning the cylinder.
Is the Airtac SAI125 Standard Air Cylinder SAI125X930SN the Right Cylinder?
With a 930 mm stroke, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear and cylinder failure, always pair this unit with an external linear guide or use a fully guided cylinder design to absorb lateral forces. If your application requires less force, stepping down to the 100 mm bore yields 3927 N at 0.5 MPa, whereas the larger 160 mm bore provides 10053 N for heavier demands.
This model uses a PT tapered G1/2 port and operates at 30-500 mm/s. Remember that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not function as a brake. If the machinery must hold a load vertically without continuous air pressure, integrate an external rod lock or select the SAIL pneumatic lock variant. As a true ISO 15552 cylinder, it serves as a drop-in replacement for any standard ISO 15552 mounting interface using TC, FA, or LB accessories.
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 SAI125 Standard Air Cylinder SAI125X930SN FAQ
The SAI125X930-S generates a push force of 6136 N at 0.5 MPa and 8590 N at 0.7 MPa, making it suitable for moving heavy loads over its 930 mm stroke.
Yes, the SAI125X930-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts using standard accessories, provided you account for the non-standard 930 mm stroke length.
