This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X900-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X900-40S 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 SIJ200X900-40S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X900-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-40S
The AirTAC SIJ200X900-40S is a discontinued double-acting single-rod adjustable-stroke ISO 15552 cylinder. An external stop screw lets you trim the extend stroke by up to 40mm on-site, giving a usable range of 860-900mm from the 900mm nominal maximum. The 200mm bore features a G3/4 port, M36x2 rod thread, and 50mm adjustable cushions at each end. The exact drop-in replacement is the SAIJ200X900-40S, matching the interface, bore, stroke, force, and mounting.
Force output is substantial: 15708N push and 15080N pull at 0.5MPa, reaching 28274N at 0.9MPa. A computed buyer insight for safe sizing yields a working load around 9425N (60% of the 0.5MPa push), or roughly 801kg for vertical lift with a 2:1 margin. The SAIJ successor retains these ratings but adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note that 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.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X900-40S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAIJ200X900-40S 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 SIJ200X900-40S Is Used
Heavy Press Tonnage Calibration
Apply up to 28274N of push force at 0.9MPa for large press operations, using the 40mm stop screw to dial in the exact 860-900mm end position without re-mounting the cylinder.
Large Mold Handling Systems
Shift heavy industrial molds with a theoretical max output of 3204kgf, relying on the 50mm adjustable cushions to safely decelerate the massive 200mm bore payload near stroke end.
Palletizer End-of-Stroke Tuning
Accommodate varying pallet heights by trimming the extend stroke on-site by up to 40mm, ensuring precise placement without needing custom-length cylinders for each load variation.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-40S with the SAIJ200X900-40S
To replace the discontinued SIJ200X900-40S, order the SAIJ200X900-40S directly—it is a drop-in match for the ISO 15552 mounting interface, 200mm bore, 900mm stroke, 40mm adjust window, and G3/4 port. If resizing, the neighboring 160mm bore yields 14074N push at 0.5MPa, while the 200mm bore provides 15708N at 0.5MPa. Choose the 40mm adjust window if your application requires fine-tuning the extend stroke between 860mm and 900mm. Mounting options include Basic, FA, LB, and TC. The -S suffix confirms a built-in piston magnet for legacy CS1-B/DS1-B switches. Because the stroke is 900mm, ensure external guides support side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X900-40S
- ✓ 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 SIJ200X900-40S FAQ
Yes, the SIJ200X900-40S is discontinued. The exact drop-in replacement is the SAIJ200X900-40S, which shares the same ISO 15552 interface, 200mm bore, 900mm stroke, 40mm adjust window, G3/4 port, and mounting options.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N at 0.9MPa, with a theoretical max of 3204kgf at 1.0MPa. The external stop screw provides a 40mm adjust window, allowing you to shorten the 900mm extend stroke down to 860mm on-site. The stop sets end position and is not a load lock.
