This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X200SH, 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.
The AirTAC Airtac SI100 Standard Cylinder SI100X200SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X200SH, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI100X200SH is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 200 mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X200SH, matching the interface, bore, stroke, force, and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. The -H suffix denotes a Viton seal for 0-150 C heat, while the -S magnet works with CS1-B/DS1-B switches.

| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X200SH produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Secures large metal castings in machining fixtures, utilizing the 3927 N push force at 0.5 MPa to hold components rigidly against cutting loads.
Drives molding presses in hot environments up to 150 C, relying on the Viton H seal option to maintain integrity without premature degradation.
To replace the SI100X200SH, order the SAI100X200SH direct, confirming the ISO 15552 mounting, G1/2 port, M20x1.5 thread, and the -S magnet with -H Viton seal. The 100 mm bore yields 3927 N push at 0.5 MPa; sizing down, an 80 mm bore gives 2513 N. For 200 mm strokes, guide rods prevent side-load rod bending. A plain cylinder drifts on air loss as cushions only decelerate; use SAIL or BSAI lock variants, or a pilot check valve to hold loads.
Replacement checklist
Yes, the SI100X200SH is discontinued. The direct replacement is the SAI100X200SH. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 200 mm stroke, output force, G1/2 port, and mounting fixtures.
This double-acting cylinder uses a G1/2 air port. At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI100X200SH replacement — usually within 7-8 hours.
