This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X700-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X700-50S 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 SIJ200X700-50S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X700-50S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X700-50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X700-50S
The AirTAC SIJ200X700-50S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and superseded by the drop-in SAIJ200X700-50S. It features a 200mm bore, a 700mm nominal extend stroke, and a G3/4 port. An external stop screw lets you trim the extend stroke by up to 50mm on-site, yielding a usable stroke window of 650-700mm. The stop sets the end position; it is not a load lock. Force output matches the standard single-rod SAI figures: 15708N push and 15080N pull at 0.5MPa.
The SAIJ replacement retains the ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 9425N (60% of the 0.5MPa push force), translating to a vertical lift capacity of about 801kg with a 2:1 margin. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that a plain cylinder does not hold loads on air loss; for held loads use an external rod lock or the SAIL/BSAI variants.

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 SAIJ200X700-50S 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 SIJ200X700-50S Is Used
Heavy Press Tonnage
Requires field tuning of the extend end position to accommodate varying material thicknesses without re-engineering the entire fixture.
Pallet Positioning Stops
Demands adjustable extend endpoints to handle different pallet footprints on the fly, ensuring precise alignment before final clamping.
Large Mold Ejection
Needs on-site stroke trimming to dial in the exact ejection distance for various mold depths, preventing over-travel damage.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X700-50S with the SAIJ200X700-50S
To replace the discontinued SIJ200X700-50S, specify the exact drop-in SAIJ200X700-50S, which preserves the 200mm bore, 700mm stroke, 50mm adjust window, G3/4 port, and ISO 15552 mounting. When sizing both ways, the neighboring 160mm bore yields 10053N push at 0.5MPa, while the 200mm bore provides 15708N at 0.5MPa and 21991N at 0.7MPa. Choose the 50mm adjust window if your application requires field tuning the extend stroke between 650mm and 700mm. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). Because the 700mm stroke exceeds 300mm, verify side-load limits, rod-bending stresses, and use external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X700-50S
- ✓ 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 SIJ200X700-50S FAQ
Yes, the SIJ200X700-50S is discontinued. The exact drop-in replacement is the SAIJ200X700-50S. It shares the same ISO 15552 interface, 200mm bore, 700mm stroke, 50mm adjust window, G3/4 port, and mounting options, while adding an upgraded piston seal.
The double-acting single-rod force set is 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N push at 0.9MPa, with a theoretical max of 3204kgf at 1.0MPa. The external stop screw provides a 50mm adjust window, allowing the extend stroke to be shortened from the 700mm maximum down to 650mm on-site. The stop sets end position and is not a load lock.
