This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X570S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100X570S
The AirTAC Airtac SI100 Standard Cylinder SI100X570S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 570mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X570S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X570S
The AirTAC SI100X570S is a discontinued double-acting ISO 15552 profile cylinder with a 570 mm stroke. Delivering 3927 N push at 0.5 MPa through a G1/2 port, it is replaced by the SAI100X570S. This direct successor shares the exact bore, stroke, force, port and mounting interface.
The SAI upgrade uses two Y-shaped one-way piston seals for low start-up pressure. The SAI family adds SAIL, SAIF and BSAI lock variants the SI lacked. Your -S model takes CS1-B/DS1-B sensors; the SAI uses current AirTAC switches.

Where the Airtac SI100 Standard Cylinder SI100X570S Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy workpiece diverters on high-capacity conveyor lines requiring a 570 mm reach and 3927 N push force.
Automated Warehousing
Actuates large load lifters and pusher arms in automated storage systems, utilizing the full 570 mm stroke to shift heavy inventory racks.
Large Press Feeding
Feeds heavy sheet metal blanks into large stamping presses, where the 100 mm bore output and long stroke accommodate deep bed loading.
Replacing the Airtac SI100 Standard Cylinder SI100X570S with the SAI100X570S
To replace this SI100X570S, order the SAI100X570S. Verify the ISO 15552 mounting interface, 100 mm bore, 570 mm stroke, G1/2 port (PT/G/NPT thread), and your -S magnet requirement. It delivers 3927 N push at 0.5 MPa; sizing down, an 80 mm bore gives 2513 N, while sizing up, a 125 mm bore yields 6136 N. For the 570 mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X570S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X570S FAQ
Yes, the AirTAC SI100X570S is discontinued. The direct replacement is the SAI100X570S. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 570 mm stroke, force, G1/2 port and mounting interface.
At 0.5 MPa it pushes 3927 N and pulls 3681 N. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical max is 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
