This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X60SFB, 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 SI160X60SFB
The AirTAC Airtac SI160 Standard Cylinder SI160X60SFB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X60SFB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X60SFB
The AirTAC SI160X60SFB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 60 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI160X60SFB, a direct replacement retaining the exact ISO 15552 mounting interface, M36x2 rod thread, FB flange, and 50 mm cushions.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces SAIL and BSAI lock variants absent in the SI line.

Where the Airtac SI160 Standard Cylinder SI160X60SFB Is Used
Heavy Stamping Press
Drives heavy-duty stamping rams requiring 10053 N push at 0.5 MPa, utilizing the 60 mm stroke for rapid, high-force metal forming cycles.
Industrial Clamp Rig
Secures large fabricated steel sections via the FB flange mount, delivering 9425 N pull force to hold components firmly during welding.
Pneumatic Press Brake
Provides steady vertical clamping using the 50 mm adjustable air cushions to decelerate the 40 mm rod safely at the end of each 60 mm stroke.
Replacing the Airtac SI160 Standard Cylinder SI160X60SFB with the SAI160X60SFB
To replace the SI160X60SFB, order the SAI160X60SFB. Verify your ISO 15552 FB flange mounting, 60 mm stroke, G3/4 port, and the -S magnet for legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). If you need less force, the 125 mm bore offers 6136 N push at 0.5 MPa; if you need more, note 160 mm is the largest standard profile before 200 mm. A plain cylinder drifts without live air, so for load holding use an external pilot check valve or the SAIL/BSAI lock variants. Even at 60 mm, ensure your guide handles side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X60SFB
- ✓ 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 SI160X60SFB FAQ
Yes, the SI160X60SFB is discontinued. The direct replacement is the SAI160X60SFB. It shares the identical ISO 15552 mounting interface, 160 mm bore, 60 mm stroke, G3/4 port, and FB flange, fitting directly into existing fixtures.
The G3/4 port feeds a 40 mm rod yielding 10053 N push and 9425 N pull at 0.5 MPa. At 0.7 MPa push is 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
