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

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-30S
The AirTAC SIJ200X900-30S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and superseded by the drop-in SAIJ200X900-30S. The external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 870-900 mm stroke. This 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa, features a 50 mm adjustable cushion, and uses a G3/4 port. The SAIJ replacement retains the exact bore, force, and mounting interface.
The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 9425 N (60% of the 0.5 MPa push), equating to an 801 kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X900-30S 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 SAIJ200X900-30S 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 SIJ200X900-30S Is Used
Heavy Press Tuning
Trimming the extend stroke by up to 30 mm on-site to set precise bottoming force on a 200 mm bore press without remachining stops.
Pallet Positioning
Adjusting the extend end position in 870-900 mm range to accommodate varying pallet lengths on a heavy-duty transfer line.
Material Rejector
Fine-tuning the pusher stroke by up to 30 mm to deflect oversized products safely without recalibrating the entire 900 mm travel.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X900-30S with the SAIJ200X900-30S
To replace the discontinued SIJ200X900-30S, order the SAIJ200X900-30S to reuse your ISO 15552 FA, LB, or TC mounts. The 30 mm adjust window allows precise extend tuning between 870 and 900 mm without machining. If sizing down, a 160 mm bore yields 10053 N push at 0.5 MPa; if sizing up, this 200 mm bore provides 15708 N. The -S magnet enables position sensing. Because the 900 mm stroke creates high rod-bending moments, external guides are critical to prevent side-load damage. The stop screw only sets end position and does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X900-30S
- ✓ 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 SIJ200X900-30S FAQ
Yes, the SIJ200X900-30S is discontinued. The exact drop-in replacement is the SAIJ200X900-30S, which matches the 200 mm bore, 900 mm stroke, 30 mm adjust window, G3/4 port, and ISO 15552 mounting. The SAIJ uses an upgraded piston seal and current switches.
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 at 0.9 MPa. The external stop screw allows trimming the extend stroke by up to 30 mm on-site (usable 870-900 mm). The stop sets end position only and is not a load lock.
