This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X180TC, 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 SI160 Standard Cylinder SI160X180TC
The AirTAC SI160 Standard Cylinder SI160X180TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 180mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X180TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X180TC
The AirTAC SI160X180TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 180 mm stroke, delivering 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X180TC, sharing the same interface, TC trunnion mount, and output. This non-magnetic SKU cannot accept a sensor.
Upgrading to the SAI brings an advanced two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

Where the Airtac SI160 Standard Cylinder SI160X180TC Is Used
Heavy Press Operations
Drives large forming and stamping presses requiring up to 18095 N of thrust at 0.9 MPa, utilizing the 50 mm adjustable cushion to absorb massive kinetic energy.
Automated Assembly Line
Actuates heavy industrial platens and large tooling fixtures on automated lines, benefiting from the rigid ISO 15552 TC trunnion interface.
Pallet Handling Systems
Indexes heavy loaded pallets through 180 mm cycles, where the robust 40 mm piston rod withstands high lateral stresses during transfer.
Replacing the Airtac SI160 Standard Cylinder SI160X180TC with the SAI160X180TC
To replace the SI160X180TC, order the SAI160X180TC. Verify the ISO 15552 TC trunnion mounting, 180 mm stroke, M36x2 rod thread, and G3/4 port. Because this SKU lacks the -S magnet, it cannot support CS1-B or DS1-B sensors; order a magnet-equipped SAI if position sensing is required. For sizing, the 160 mm bore yields 10053 N push at 0.5 MPa; dropping to a 125 mm bore reduces push to 6136 N, while increasing to 200 mm provides 15708 N. Since the 180 mm stroke is under 300 mm, side-load risks are minimal, but ensure adequate guidance. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X180TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X180TC FAQ
Yes, the SI160X180TC is discontinued. The direct replacement is the SAI160X180TC. It features the same ISO 15552 TC trunnion mounting, 160 mm bore, 180 mm stroke, output force, and G3/4 port, fitting directly into existing fixtures.
This double-acting cylinder uses a G3/4 air port. The thrust is 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and 18095 N push at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
