About the Airtac SAI100 Standard Air Cylinder SAI100X1250SN
The AirTAC SAI100X1250-S is a double-acting ISO 15552 profile cylinder engineered for substantial thrust, generating 5497 N of push force at 0.7 MPa. Equipped with a 1250 mm stroke, this made-to-order unit is built for automated machinery requiring extensive linear reach. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that conforms precisely to standardized ISO 15552 mounting dimensions.
This specific configuration incorporates a -S magnet for seamless integration with CMSE or DMSE sensor switches along the dual-side grooves. It features a robust carbon steel piston rod paired with NBR seals, providing dependable service within the -20 to +70 C operating range. The PT tapered port threading ensures a positive, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X1250SN Is Used
Extended Transfer Lines
Drives long-stroke pushers across multi-station conveyor networks to advance heavy pallets between robotic work cells.
Large Press Feeding
Feeds bulky sheet metal blanks into wide mechanical presses where a 5497 N push force at 0.7 MPa is required to move the mass.
High-Bay Extraction
Extracts heavy totes from deep automated storage and retrieval system aisles, utilizing the full 1250 mm extension.
Is the Airtac SAI100 Standard Air Cylinder SAI100X1250SN the Right Cylinder?
Selecting this 100 mm bore over the neighboring 80 mm variant steps thrust up from 3518 N to 5497 N at 0.7 MPa, whereas stepping down to a 63 mm bore drops output to 2182 N. Because this model features a 1250 mm stroke, which exceeds the 1500 mm standard maximum, it is supplied as a non-standard made-to-order item.
An unsupported rod of this length is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, mount this cylinder using an external guide rail or specify a fully guided actuator. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock the load. If your application requires position holding without live air pressure, utilize the SAIL locking variant or an external pilot-operated check valve. For ISO 15552 drop-in replacements, match the 100 mm bore, 1250 mm stroke, G1/2 port, and TC trunnion or FA flange accessories, ensuring the -S magnet is specified.
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 SAI100 Standard Air Cylinder SAI100X1250SN FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force.
No, the adjustable air cushions only decelerate the piston at stroke end and do not act as a brake. For position holding without live pressure, use the SAIL lock variant or an external rod lock.
