This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1000SLB, 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 SI200X1000SLB
The AirTAC SI200 Standard Cylinder SI200X1000SLB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1000mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X1000SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X1000SLB
The AirTAC SI200X1000SLB is a discontinued double-acting ISO 15552 profile cylinder featuring a 200 mm bore and 1000 mm stroke. Built with an extruded aluminum barrel and adjustable air cushions, it delivers 15708 N of push force and 15080 N of pull force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAI200X1000SLB. This current-production direct maintains the exact ISO 15552 mounting interface, 1000 mm stroke, G3/4 port, and M36x2 rod thread, fitting existing LB foot fixtures seamlessly.
The SAI upgrade introduces a refined piston seal using two Y-shaped one-way elements for lower start-up pressure and extended life. The original SI includes a -S magnet for CS1-B/DS1-B legacy sensors, while the SAI family expands capabilities with SAIL air-released lock and BSAI clamp-lock variants absent in the legacy line.

Where the Airtac SI200 Standard Cylinder SI200X1000SLB Is Used
Heavy Stamp Presses
Drives large metal forming dies requiring 15708 N push force at 0.5 MPa, utilizing the 1000 mm stroke for deep-draw operations.
Bulk Material Diversion
Actuates heavy-duty diverter gates on aggregate lines, using the adjustable 50 mm air cushions to decelerate massive loads at stroke ends.
Replacing the Airtac SI200 Standard Cylinder SI200X1000SLB with the SAI200X1000SLB
To replace the discontinued SI200X1000SLB, order the SAI200X1000SLB. Verify your existing LB foot mounting hardware aligns with the ISO 15552 interface, and confirm the G3/4 port and M36x2 rod thread. The -S magnet equates to legacy CS1-B/DS1-B sensors, which should be upgraded to current AirTAC switches on the SAI. When sizing, note this 200 mm bore yields 15708 N push at 0.5 MPa; dropping to a 160 mm bore reduces push to 10053 N. For load holding, remember a standard cylinder drifts on air loss as cushions only decelerate. Employ an external rod lock, pilot check valve, or the SAIL/BSAI lock variants for secure holding. Given the 1000 mm stroke, external guides are critical to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X1000SLB
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
