This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X330STC, 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 SI160X330STC
The AirTAC SI160 Standard Cylinder SI160X330STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 330mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X330STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X330STC
The AirTAC SI160X330STC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 330 mm stroke. It delivers a push force of 10053 N at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X330STC, matching the bore, stroke, force, port, and TC trunnion mount.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family adds SAIL and BSAI lock variants the SI lacked. This -S SKU uses CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160X330STC Is Used
Heavy Press Operations
Drives large forming and stamping presses requiring up to 14074 N at 0.7 MPa, utilizing the 50 mm adjustable cushions to absorb heavy end-of-stroke impacts.
Pallet Lifting Systems
Lifts substantial loads with a safe working capacity around 6032 N, ideal for elevating heavy industrial pallets when guided externally to prevent rod bending.
Large Clamp Fixtures
Secures oversized components during machining, providing 9425 N pull force at 0.5 MPa while maintaining steady position via the TC trunnion mount.
Replacing the Airtac SI160 Standard Cylinder SI160X330STC with the SAI160X330STC
To replace the SI160X330STC, order the SAI160X330STC. Verify the ISO 15552 TC trunnion interface, 330 mm stroke, G3/4 port, M36x2 rod thread, and the -S magnet for CS1-B/DS1-B switches. The 50 mm cushions decelerate but do not hold load; for air-loss holding use the SAIL/BSAI lock variants or an external pilot check valve. At 0.5 MPa it pushes 10053 N (neighbor bore 125 pushes 6136 N; 200 pushes 15708 N). For the 330 mm stroke, use an external guide to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X330STC
- ✓ 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 SI160X330STC FAQ
Yes, the SI160X330STC is discontinued. The direct replacement is the SAI160X330STC. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 330 mm stroke, TC mount, G3/4 port, and 10053 N force, fitting existing fixtures perfectly.
The 160 mm bore uses a G3/4 port. At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
