This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X900-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X900-75 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 SIJ200X900-75
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-75 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 SAIJ200X900-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-75
The AirTAC SIJ200X900-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. A 200mm bore and 900mm nominal stroke pair with an external stop screw that lets you trim the extend stroke by up to 75mm on-site, yielding a usable 825-900mm extension. The G3/4 port and 50mm adjustable cushions manage the massive 15708N push and 15080N pull forces at 0.5MPa. The exact drop-in replacement is the SAIJ200X900-75, matching the bore, stroke, force, and mounting.
The SAIJ successor retains the ISO 15552 interface but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, a safe working load is roughly 9425N (60% of the 0.5MPa push), translating to an 801kg vertical lift with a 2:1 margin. Remember the stop screw sets end position only; it is not a lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X900-75 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 SAIJ200X900-75 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 SIJ200X900-75 Is Used
Heavy Press Tonnage
Provides 28274N push at 0.9MPa for large forming presses, using the 75mm stop screw to dial in the exact 825-900mm closure position on-site.
Palletizer End Stops
Handles 801kg vertical lifts with a 2:1 safety margin, allowing field adjustment of the extend stroke to accommodate varying pallet heights without changing the cylinder.
Large Mold Clamping
Secures heavy industrial molds using the 50mm adjustable cushions to decelerate massive payloads, relying on external guides to prevent rod bending over the 900mm extension.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-75 with the SAIJ200X900-75
To replace the discontinued SIJ200X900-75, order the drop-in SAIJ200X900-75, which preserves the 900mm stroke, 75mm adjust window, G3/4 port, and ISO 15552 mounting footprint. When sizing both ways, the neighboring 160mm bore yields 10053N push at 0.5MPa, while this 200mm bore reaches 21991N push at 0.7MPa. Choose the 75mm adjust window if your end-position tuning requires that exact 825-900mm trim flexibility. Reuse existing FA, LB, or TC mounts. Because this is a non-magnet SKU (no -S suffix), it cannot accept a magnetic switch. For the 900mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X900-75
- ✓ 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 SIJ200X900-75 FAQ
Yes, the SIJ200X900-75 is discontinued. The exact drop-in replacement is the SAIJ200X900-75, which matches the 200mm bore, 900mm stroke, 75mm adjust window, G3/4 port, and ISO 15552 mounting. The SAIJ family also features an upgraded piston seal for longer life.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N push at 0.9MPa. The external stop screw provides a 75mm adjustment window, allowing you to trim the extend stroke from 900mm down to 825mm on-site. The stop sets position only and is not a load lock.
