This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX60, 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 SI200 Standard Cylinder SI200BX60
The AirTAC Airtac SI200 Standard Cylinder SI200BX60 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX60, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX60
The AirTAC SI200BX60 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 60 mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200BX60, a direct upgrade retaining the exact mounting interface, bore, stroke, force, and port size.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU lacks a magnet, so it cannot accept a CS1-B/DS1-B sensor. For load holding, note that the cushion only decelerates; you need an external rod lock or the SAIL/BSAI variants.

Where the Airtac SI200 Standard Cylinder SI200BX60 Is Used
Heavy Stamping
Drives large presses and stamping fixtures requiring immense thrust, utilizing the 15708 N push force at 0.5 MPa to form thick steel plates.
Clamp Systems
Secures massive workpieces in heavy machining centers where the 15080 N pull force at 0.5 MPa ensures rigid holding during aggressive milling.
Replacing the Airtac SI200 Standard Cylinder SI200BX60 with the SAI200BX60
To replace the discontinued SI200BX60, order the SAI200BX60. Verify your ISO 15552 mounting interface, 200 mm bore, 60 mm stroke, G3/4 port, and M36x2 rod thread. Because this is a non-magnet SKU, it cannot support position sensing; if you need switches, select an SAI equivalent with the -S suffix for CS1-B/DS1-B compatibility. For applications requiring load holding on air loss, upgrade to the SAIL air-released lock or BSAI clamp-lock variant, or use a pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX60
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI200 Standard Cylinder SI200BX60 FAQ
Yes, the SI200BX60 is discontinued. The direct replacement is the SAI200BX60. It is dimensionally interchangeable per ISO 15552, matching the 200 mm bore, 60 mm stroke, 15708 N force, and G3/4 port so it fits existing fixtures perfectly.
This double-acting cylinder uses a G3/4 air port. It delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. The rod is 40 mm with an M36x2 thread.
