This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X75-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X75-75 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 SIJ200X75-75
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X75-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-75
The AirTAC SIJ200X75-75 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore. Its external stop screw lets you trim the extend stroke by up to 75mm on-site, dropping the usable extension from the 75mm nominal maximum down to zero. The G3/4 port and 40mm rod deliver a push of 15708N and pull of 15080N at 0.5MPa. This SIJ model is discontinued; the exact drop-in replacement is the SAIJ200X75-75, retaining the same interface, force, and adjustability.
The SAIJ successor introduces an upgraded piston seal featuring two Y-shaped one-way elements for low start-up pressure and extended life. For sizing, a safe working load is roughly 9425N (60% of the 0.5MPa push), yielding an 801kg vertical lift capacity with a 2:1 margin. The external stop sets the end position but is not a load lock; for held loads, use an external rod lock or the SAIL/BSAI variants. This SKU lacks a magnet and cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X75-75 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 SAIJ200X75-75 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 SIJ200X75-75 Is Used
Heavy Press Tonnage
Demands field stroke tuning to set precise 0-75mm extend endpoints during heavy press tooling changes without swapping cylinders.
Industrial Forming
Requires adjustable extend stops to accommodate varying material thicknesses on-site, utilizing the 200mm bore's 15708N push force.
Large Assembly Jigs
Needs exact extend positioning for multi-part alignment, trimming the stroke by up to 75mm to prevent jig overtravel.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-75 with the SAIJ200X75-75
To replace the discontinued SIJ200X75-75, order the drop-in SAIJ200X75-75, which preserves the ISO 15552 mounting interface, G3/4 port, and 75mm adjust window. 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 75mm adjust window if your assembly requires on-site extend tuning from 0 to 75mm; otherwise, a fixed SAI cylinder is simpler. Mounting options include Basic, FA, LB, and TC. Because this SKU has no -S suffix, it cannot accept a magnetic sensor. For strokes at or above 300mm, carefully manage side loading to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X75-75
- ✓ 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 SIJ200X75-75 FAQ
Yes, the SIJ200X75-75 is discontinued. The exact drop-in replacement is the SAIJ200X75-75. It shares the same ISO 15552 interface, 200mm bore, 75mm stroke, 75mm adjust window, G3/4 port, and mounting options, but adds an upgraded piston seal.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, 28274N at 0.9MPa, and a 3204kgf max at 1.0MPa. The external stop screw window is 75mm, meaning you can shorten the extend stroke by up to 75mm on-site. The stop sets end position and is not a load lock.
