This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-40S 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 SIJ200X80-40S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X80-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-40S
The AirTAC SIJ200X80-40S is a double-acting, single-rod ISO 15552 adjustable-stroke cylinder with a 200 mm bore and an 80 mm nominal extend stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 40-80 mm window. The stop sets the end position but is not a load lock. This bore delivers 15708 N push and 15080 N pull at 0.5 MPa, features a Ø40 mm rod, M36x2 thread, and a G3/4 port. This SIJ model is discontinued; the exact drop-in replacement is the SAIJ200X80-40S, sharing the same interface, force, and mounting.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is ~9425 N (60% of the 0.5 MPa push), and vertical lift is ~801 kg with a 2:1 margin. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder drifts on air loss; use an external rod lock or SAIL/BSAI variant for held loads.

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 SAIJ200X80-40S 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 SIJ200X80-40S Is Used
Heavy Press Tuning
Field-trim the 40 mm extend window on a 200 mm bore press to set precise 28274 N contact force at 0.9 MPa without remachining stops.
Large Mold Positioning
Adjust the extend stroke on-site to accommodate varying mold heights, utilizing the 15708 N push force for heavy industrial tooling.
Calibrated Lowering Stops
Regulate descent end-position for heavy platens, knowing the external screw sets the stop but a rod lock is required for load holding.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-40S with the SAIJ200X80-40S
To replace the discontinued SIJ200X80-40S, order the drop-in SAIJ200X80-40S, retaining the 200 mm bore, 80 mm nominal stroke, 40 mm adjust window, and G3/4 port. Size both ways: the 160 mm neighbor yields 10053 N push at 0.5 MPa, while the 200 mm provides 15708 N. The 40 mm adjust window is ideal for field tuning without machining. Mounting includes Basic, FA, LB, and TC. The -S suffix ensures a piston magnet for legacy CS1-B/DS1-B switches. For stroke lengths >=300 mm, verify side-load guidance to prevent rod deflection.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-40S
- ✓ 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 SIJ200X80-40S FAQ
Yes, the SIJ200X80-40S is discontinued. The exact drop-in replacement is the SAIJ200X80-40S. It shares the identical ISO 15552 interface, 200 mm bore, 80 mm stroke, 40 mm adjust window, G3/4 port, and mounting options, but adds an upgraded 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 at 0.9 MPa (max 3204 kgf at 1.0 MPa). The external stop screw allows trimming the extend stroke by up to 40 mm on-site (usable 40-80 mm). Speed is 30-500 mm/s.
