This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X900-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X900-20 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 SIJ200X900-20
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-20 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 SAIJ200X900-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-20
The AirTAC SIJ200X900-20 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 900 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable range of 880-900 mm. This stop sets the end position; it is not a load lock. The 200 mm bore features a G3/4 port, M36x2 rod thread, and 50 mm adjustable cushions. It delivers 15708 N push and 15080 N pull at 0.5 MPa.
This SIJ series is discontinued; the exact drop-in replacement is the SAIJ200X900-20, matching the interface, force, and port. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, a safe working load is roughly 9425 N (60% of the 0.5 MPa push), allowing a vertical lift of about 801 kg with a 2:1 margin. Note: this SKU lacks a -S magnet and cannot take a switch.

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 SAIJ200X900-20 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 SIJ200X900-20 Is Used
Heavy Press Positioning
Trimming the extend stroke by up to 20 mm on-site allows precise bottom-dead-center calibration for a 200 mm bore press without machining hard stops.
Large Mold Closure
Field-tuning the 880-900 mm extend stroke ensures two large mold halves close with exact parallelism, absorbing minor mechanical deviations.
Bulk Material Compaction
Adjusting the extend end position on-site lets operators vary the final compaction volume in a large hopper while utilizing the full 15708 N push force.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-20 with the SAIJ200X900-20
To replace the discontinued SIJ200X900-20, order the drop-in SAIJ200X900-20. For sizing both ways, the neighbouring 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore offers 21991 N push at 0.7 MPa. The 20 mm adjust window is ideal for precise extend positioning within the 880-900 mm range. Mounting reuses ISO 15552 interfaces like FA, LB, or TC. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. At 900 mm stroke, mind side-load and rod-bending forces; use external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X900-20
- ✓ 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 SIJ200X900-20 FAQ
Yes, the SIJ200X900-20 is discontinued. The exact drop-in replacement is the SAIJ200X900-20. It shares the same ISO 15552 interface, 200 mm bore, 900 mm stroke, 20 mm adjust window, G3/4 port, and mounting options, while adding an upgraded SAI piston seal.
The 200 mm bore provides 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa, with a theoretical max of 3204 kgf at 1.0 MPa. The external stop screw provides a 20 mm adjust window, making the usable extend stroke 880-900 mm. The stop sets end position and is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.
