This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X900-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X900-30 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 SIJ200X900-30
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-30 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 SAIJ200X900-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-30
The AirTAC SIJ200X900-30 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200 mm bore and 900 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 870-900 mm stroke window. This stop sets the end position but is not a load lock. The exact drop-in replacement is the SAIJ200X900-30, matching the ISO 15552 interface, G3/4 port, M36x2 rod thread, and 50 mm cushions.
Force output is substantial: 15708 N push and 15080 N pull at 0.5 MPa, rising to 28274 N push at 0.9 MPa (theoretical max 3204 kgf at 1.0 MPa). Computed buyer insight: 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. The SAIJ upgrade uses an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. This non-magnet SKU cannot accept a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X900-30 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 SAIJ200X900-30 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 SIJ200X900-30 Is Used
Heavy Press Tonnage
Provides 15708 N push at 0.5 MPa for large forming presses, using the 30 mm stop screw to dial in the exact 870-900 mm contact position without re-plumbing the G3/4 air supply.
Bulk Pallet Positioning
Shifts heavy pallets in automated warehouses, where the adjustable end-stop accommodates varying pallet heights and the 900 mm reach requires external guides to prevent rod bending.
Large Mold Ejection
Ejects substantial injection molds, using the 50 mm adjustable cushions to decelerate the 3204 kgf max force, while the external stop screw fine-tunes the ejection length.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-30 with the SAIJ200X900-30
To replace the discontinued SIJ200X900-30, order the drop-in SAIJ200X900-30, reusing your existing FA, LB, or TC ISO 15552 mounts. When sizing both ways, the neighboring 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore provides 15708 N. The 30 mm adjust window is ideal if your extend stroke needs final on-site tuning between 870 and 900 mm. Because this is a non-S SKU, it cannot accept a magnetic switch; for sensing, confirm from datasheet or select a -S model. For the 900 mm stroke, use external guides to prevent rod bending and side-load damage. The stop screw sets end position only; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X900-30
- ✓ 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 SIJ200X900-30 FAQ
Yes, the SIJ200X900-30 is discontinued. The exact drop-in replacement is the SAIJ200X900-30, which shares the identical ISO 15552 interface, 200 mm bore, 900 mm stroke, 30 mm adjust window, G3/4 port, and mounting options. The SAIJ family also features an upgraded two-piece Y-shaped piston seal for longer life.
The 200 mm bore delivers 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 (max 3204 kgf at 1.0 MPa). The external stop screw provides a 30 mm adjustment window, allowing the extend stroke to be shortened from 900 mm to 870 mm on-site. The stop sets end position and is not a load lock; speeds are 30-500 mm/s.
