This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-30S in place of this model. 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 SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X800-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30S
The AirTAC SIJ200X800-30S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200 mm bore and 800 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 770-800 mm extend window. This bore delivers 15708 N push and 15080 N pull at 0.5 MPa via its G3/4 port. The SIJ family is discontinued; the exact drop-in replacement is the SAIJ200X800-30S, retaining the same ISO 15552 mounting interface, force, and adjust window.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, a safe working load is roughly 9425 N (60% of the 0.5 MPa push), translating to an 801 kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock for held loads. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAIJ200X800-30S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30S Is Used
Heavy Press Tonnage
Applies up to 28274 N of push force at 0.9 MPa for forming operations, using the 30 mm stop screw to precisely set the bottom dead center on-site without machine reconfiguration.
Bulk Pallet Positioning
Shifts heavy loads vertically with a safe working load around 9425 N, adjusting the extend stroke within the 770-800 mm window to accommodate varying pallet heights.
Large Mold Ejection
Ejects substantial industrial molds from machinery, utilizing the 50 mm adjustable air cushions at each end to safely decelerate the 40 mm rod before impact.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30S with the SAIJ200X800-30S
To replace the discontinued SIJ200X800-30S, order the drop-in SAIJ200X800-30S, which preserves the 200 mm bore, 800 mm stroke, 30 mm adjust window, M36x2 rod thread, and G3/4 port. When sizing both ways, the neighboring 160 mm bore yields 10053 N push at 0.5 MPa, while this 200 mm bore provides 15708 N at 0.5 MPa and 21991 N at 0.7 MPa. Select the 30 mm adjust window if your application requires fine-tuning the extend end position within a 770-800 mm range. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a built-in magnet for position sensing. Because the stroke is 800 mm, ensure external guides support side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-30S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30S FAQ
Yes, the SIJ200X800-30S is discontinued. The exact drop-in replacement is the SAIJ200X800-30S. It shares the same ISO 15552 interface, 200 mm bore, 800 mm stroke, 30 mm adjust window, G3/4 port, and force ratings, but features an upgraded two Y-shaped one-way piston seal for longer life.
The 200 mm bore provides 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 external stop screw provides a 30 mm adjust window, allowing you to shorten the 800 mm extend stroke down to 770 mm. Note that the stop sets end position and is not a load lock.
