This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX130S, 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 SI160 Standard Cylinder SI160AX130S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 130mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX130S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160AX130S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 130 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160AX130S, matching the bore, stroke, force, port and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SI160AX130S uses a SUS420J2 stainless rod (-A) and includes a magnet (-S) for CS1-B/DS1-B sensors.

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).
Drives large forming and stamping presses requiring 10053 N of push force at 0.5 MPa, utilizing the 130 mm stroke for high-impact actuation.
Secures large fabricated components during machining or welding, relying on the rigid ISO 15552 mounting interface to withstand severe side loads.
To replace the SI160AX130S, order the SAI160AX130S. Verify the ISO 15552 mounting interface, 130 mm stroke, G3/4 port, and mounting accessories. The -S magnet enables current AirTAC switches (legacy used CS1-B/DS1-B). The -A rod is SUS420J2 stainless steel. At 0.5 MPa it pushes 10053 N; if undersized, the 200 mm bore offers more force. 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 variants. Viton H seals raise heat to 150 C.
Replacement checklist
Yes, the SI160AX130S is discontinued. The direct replacement is the SAI160AX130S. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 130 mm stroke, 10053 N force, G3/4 port, and mounting interface.
It features a G3/4 port and delivers a push force of 10053 N and pull of 9425 N at 0.5 MPa. At 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical max force is 2050 kgf at 1.0 MPa, operating at 30-500 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI160AX130S replacement — usually within 7-8 hours.
