This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX30, 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 SI160BX30
The AirTAC SI160 Standard Cylinder SI160BX30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX30
The AirTAC SI160BX30 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 30 mm stroke. Built for heavy thrust, it delivers 10053 N push at 0.5 MPa. The direct replacement is the SAI160BX30, matching the exact bore, stroke, force, G3/4 port, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This specific SKU uses a SUS304 stainless steel rod (-B) and lacks a magnet (-S), meaning it cannot accept CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160BX30 Is Used
Heavy-Duty Pressing
Drives 10053 N of thrust at 0.5 MPa for seating large bearings or assembling heavy structural components.
Stamping Operations
Short 30 mm stroke provides rigid, high-force impact for metal forming and stamping tasks within confined spaces.
High-Force Clamping
Secures large workpieces during machining, utilizing the SUS304 stainless rod for corrosive resistance in harsh environments.
Replacing the Airtac SI160 Standard Cylinder SI160BX30 with the SAI160BX30
To replace this SI160BX30, order the SAI160BX30: confirm the ISO 15552 mounting interface, 160 mm bore, 30 mm stroke, G3/4 port, and SUS304 rod. This non-magnetic SKU cannot take a sensor; if position detection is needed, select an SAI160BX30S and use current AirTAC switches. For load holding, note that a standard cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock, pilot check valve, or use the SAIL/BSAI lock variant. If sizing down, the 125 mm bore yields 6136 N push at 0.5 MPa; if sizing up, the 200 mm bore yields 15708 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX30
- ✓ 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 SI160BX30 FAQ
Yes, the AirTAC SI160BX30 is discontinued. The direct replacement is the SAI160BX30, which is dimensionally interchangeable per ISO 15552. It maintains the same 160 mm bore, 30 mm stroke, output force, G3/4 port, and mounting interface.
At 0.5 MPa, it pushes 10053 N and pulls 9425 N. At 0.7 MPa it pushes 14074 N, and the theoretical max force is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s. It features a 40 mm rod, M36x2 thread, and 50 mm cushions.
