This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X900H, 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 SI160X900H
The AirTAC SI160 Standard Cylinder SI160X900H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X900H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X900H
The AirTAC SI160X900H is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 900 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X900H, which matches the interface, force, and port exactly while adding an upgraded piston seal with two Y-shaped elements for low start-up pressure. This H-seal variant uses Viton FKM for 0-150 C heat resistance. Without a -S magnet, this SKU cannot take a sensor. The 900 mm stroke requires external guides to prevent rod bending.
The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line.

Where the Airtac SI160 Standard Cylinder SI160X900H Is Used
Heavy Stamp Press
Drives large tonnage metal forming presses where the 14074 N push at 0.7 MPa and high-temp Viton H seals withstand generated friction heat.
Mold Actuation
Opens and closes heavy industrial molds on rubber injection machinery, exploiting the 2050 kgf max force and 900 mm travel distance.
Pallet Diversion
Shifts massive loaded pallets across high-speed packaging lines, requiring external guides to manage the 900 mm stroke side-load safely.
Replacing the Airtac SI160 Standard Cylinder SI160X900H with the SAI160X900H
To replace the SI160X900H, order the SAI160X900H. Verify the ISO 15552 mounting interface, 160 mm bore, 900 mm stroke, G3/4 port, and M36x2 rod thread. Because this lacks a -S suffix, it cannot accept a magnetic sensor; if sensing is needed, order an SAI with the S magnet option for CS1-B/DS1-B switches. This Viton H seal raises operating temperature to 150 C. For the 900 mm stroke, use external guides to prevent rod bending under side loads. If sizing down, a 125 mm bore gives 6136 N push at 0.5 MPa; sizing up to 200 mm provides 15708 N. A plain cylinder drifts without air; for load holding use the SAIL lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X900H
- ✓ 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 SI160X900H FAQ
Yes, the SI160X900H is discontinued. The direct replacement is the SAI160X900H. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 900 mm stroke, G3/4 port, and mounting fixtures, but features an upgraded piston seal for lower start-up pressure.
The 160 mm bore uses a G3/4 port and M36x2 rod thread. Force output is 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
