This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAIJ200X900-75S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 SIJ200X900-75S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-75S 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 SAIJ200X900-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-75S
The AirTAC SIJ200X900-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 900mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable forward travel of 825-900mm. This stop sets the end position; it is not a load lock. The exact drop-in replacement is the SAIJ200X900-75S, matching the G3/4 port, M36x2 rod thread, and 50mm adjustable cushions.
Force output is substantial: push 15708N and pull 15080N at 0.5MPa, scaling to 28274N at 0.9MPa. A computed buyer insight sets the safe working load around 9425N (60% of the 0.5MPa push), allowing a vertical lift of roughly 801kg with a 2:1 margin. The SAIJ successor retains these ratings but adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X900-75S 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 SAIJ200X900-75S 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 SIJ200X900-75S Is Used
Heavy Press Tonnage
Apply up to 28274N of push force at 0.9MPa for forming operations, using the 75mm stop screw to fine-tune the bottom dead center on-site without re-mounting the tooling.
Bulk Pallet Positioning
Index large 801kg vertical loads with a 2:1 safety margin, adjusting the extend stroke within the 825-900mm window to accommodate varying pallet heights or stack depths.
Oversized Product Diversion
Divert heavy manufactured goods on a conveyor by dialing in the exact extend position required by different product widths, relying on the 50mm adjustable cushions to decelerate the 40mm rod safely.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-75S with the SAIJ200X900-75S
To replace the discontinued SIJ200X900-75S, order the drop-in SAIJ200X900-75S; it reuses the exact ISO 15552 mounting interface and FA, LB, or TC foot brackets. When sizing both ways, the neighbouring 160mm bore yields 10053N push at 0.5MPa, while the 200mm bore delivers 15708N at 0.5MPa or 21991N at 0.7MPa. Choose the 75mm adjust window if your extend endpoint needs on-site tuning between 825 and 900mm. Because the 900mm stroke invites rod bending, use external guides to manage side loads. The -S magnet supports legacy CS1-B/DS1-B switches, while the SAIJ uses current sensors. For load holding without live air, select an external rod lock or the SAIL/BSAI variant, as the stop screw is not a brake.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X900-75S
- ✓ 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 SIJ200X900-75S FAQ
Yes, the SIJ200X900-75S is discontinued. The exact drop-in replacement is the SAIJ200X900-75S. It shares the identical ISO 15552 interface, 200mm bore, 900mm stroke, 75mm adjust window, G3/4 port, and mounting options, but features an upgraded piston seal for longer life.
The double-acting single-rod force figures are 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N push at 0.9MPa (theoretical max 3204kgf at 1.0MPa). The external stop screw allows you to shorten the extend stroke by up to 75mm on-site, giving a usable forward travel of 825-900mm. Note that this stop sets the end position and is not a load lock; a plain cylinder drifts on air loss.
