This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X900-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X900-40 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 SIJ200X900-40
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-40 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 SAIJ200X900-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-40
The AirTAC SIJ200X900-40 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. A 200mm bore yields 15708N push and 15080N pull at 0.5MPa. The external stop screw lets you trim the extend stroke by up to 40mm on-site, giving a usable 860-900mm window from the 900mm nominal maximum. The drop-in replacement is the SAIJ200X900-40, matching the G3/4 port, M36x2 thread, and 50mm cushion.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Computed buyer insight: safe working load is ~9425N (60% of the 0.5MPa push), yielding an 801kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a lock. This non-magnetic SKU cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X900-40 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 SAIJ200X900-40 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 SIJ200X900-40 Is Used
Heavy Press Positioning
Needs field stroke tuning to set precise 860-900mm press endpoints on-site, absorbing mechanical tolerance variations without re-machining components.
Large Material Ejector
Requires adjusting the extend stroke by up to 40mm to tune the ejection distance of heavy fabricated parts safely before final commissioning.
Mold Clamping Station
Demands exact end-position limits via the external stop screw for varying mold heights, ensuring positive mechanical positioning without relying on air pressure.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-40 with the SAIJ200X900-40
Replace the discontinued SIJ200X900-40 directly with the SAIJ200X900-40 (drop-in ISO 15552 interface, identical 900mm stroke and 40mm adjust window). To size both ways: the neighboring 160mm bore gives 10053N push @0.5MPa, while the 200mm bore gives 15708N. The 40mm adjust window is ideal for precise extend positioning without machining. Mounting options include FA, LB, and TC brackets. Because this is a non-S SKU, it cannot accept a magnetic switch; for sensing, confirm from datasheet or select an -S model. For the 900mm stroke, use external guides to prevent rod bending and manage side loads. Never rely on the stop screw or cushions for load holding; use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X900-40
- ✓ 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 SIJ200X900-40 FAQ
Yes, the SIJ200X900-40 is discontinued. The exact drop-in replacement is the SAIJ200X900-40. It shares the same ISO 15552 interface, 200mm bore, 900mm stroke, 40mm adjust window, G3/4 port, and 50mm cushion. The SAIJ features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The SIJ200X900-40 delivers 15708N push and 15080N pull @0.5MPa, 21991N push @0.7MPa, and 28274N push @0.9MPa (theoretical max 3204 kgf @1.0MPa). The external stop screw provides a 40mm adjust window, allowing you to trim the extend stroke from the 900mm nominal maximum down to 860mm on-site. The stop sets end position only; it is not a load lock.
