This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-20S 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 SIJ200X800-20S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-20S 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 SAIJ200X800-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-20S
The AirTAC SIJ200X800-20S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 20 mm on-site, giving a usable 780-800 mm window from the 800 mm nominal maximum. The 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa, scaling to 28274 N push at 0.9 MPa. It features a 40 mm rod, M36x2 thread, 50 mm adjustable cushions, a G3/4 port, and a built-in magnet for legacy CS1-B/DS1-B switches. The drop-in replacement is the SAIJ200X800-20S, matching the interface, bore, stroke, force, port, and mounting.
The SAIJ upgrade uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 9425 N (60% of the 0.5 MPa push), yielding an 801 kg vertical lift with a 2:1 margin. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

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 SAIJ200X800-20S 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 SIJ200X800-20S Is Used
Heavy Press Tonnage
Needs field stroke tuning to precisely set the 780-800 mm extend contact point on large stamping dies without mechanical shimming.
Oversized Pallet Forming
Requires adjustable end-positioning to accommodate varying pallet heights on the fly, ensuring exact 20 mm trim capability for final compaction.
Large Mold Clamping
Demands exact bottom-dead-center positioning for heavy injection molds, using the stop screw to dial in the final extend length securely.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-20S with the SAIJ200X800-20S
To replace the discontinued SIJ200X800-20S, use the SAIJ200X800-20S directly—it preserves the 200 mm bore, 800 mm stroke, 20 mm adjust window, G3/4 port, and ISO 15552 mounting. When sizing both ways, the 160 mm neighbor yields 10053 N push at 0.5 MPa, while the 200 mm bore provides 15708 N. Choose the 20 mm adjust window if you need 780-800 mm fine-tuning; for larger trims, select a different adjust code. Mounting options include Basic, FA, LB, and TC. The -S suffix ensures a piston magnet for CS1-B/DS1-B switches. Because the 800 mm stroke is long, account for side-load and rod-bending by using external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-20S
- ✓ 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 SIJ200X800-20S FAQ
Yes, the SIJ200X800-20S is discontinued. The exact drop-in replacement is the SAIJ200X800-20S, which shares the same ISO 15552 interface, 200 mm bore, 800 mm stroke, 20 mm adjust window, G3/4 port, and mounting options.
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 offers a 20 mm trim window, allowing the extend stroke to be shortened from 800 mm to 780 mm on-site.
