This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-20S 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 SIJ200X80-20S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20S 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 SAIJ200X80-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20S
The AirTAC SIJ200X80-20S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 20 mm on-site, giving a usable 60-80 mm extend window from the 80 mm nominal maximum. This 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa, features a 50 mm adjustable air cushion at each end, and uses a G3/4 port. Because the SIJ line is end-of-life, the exact drop-in replacement is the SAIJ200X80-20S—matching the interface, bore, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting dimensions for direct hardware reuse and upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Computed buyer insight: using the 0.5 MPa push figure, the safe working load is about 9425 N (60% of 15708 N), and a vertical lift with a 2:1 safety margin handles approximately 801 kg. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that the external stop sets the end position but is not a load lock; for held loads use an external rod lock or the SAIL/BSAI variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-20S 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 SAIJ200X80-20S 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 SIJ200X80-20S Is Used
Heavy Press Tonnage
Apply up to 21991 N of push force at 0.7 MPa for forming operations, using the stop screw to fine-tune the 60-80 mm extend distance precisely to the material thickness.
Pallet Positioning Stops
Act as a heavy-duty end stop in high-tonnage conveyors. The 20 mm adjust window lets operators dial in the exact stopping point for varying pallet dimensions without changing mounts.
Large Fixture Clamping
Secure oversized aerospace or automotive fixtures. The 200 mm bore provides immense holding power, while the external stop ensures the clamp bottoms out exactly at 60-80 mm.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20S with the SAIJ200X80-20S
To replace the discontinued SIJ200X80-20S, order the SAIJ200X80-20S (insert A after the leading S) for an exact drop-in fit. When sizing both ways, the 160 mm neighbor bore provides 10053 N push at 0.5 MPa, while the 200 mm bore provides 15708 N. The 20 mm adjust window is selected when your application needs on-site extend tuning between 60 and 80 mm. Mounting options include Basic, FA, LB, and TC. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B sensors. For strokes at or above 300 mm, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-20S
- ✓ 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 SIJ200X80-20S FAQ
Yes, the SIJ200X80-20S is discontinued. The exact drop-in replacement is the SAIJ200X80-20S, which shares the identical ISO 15552 interface, 200 mm bore, 80 mm stroke, 20 mm adjust window, G3/4 port, and mounting options. The SAIJ also features an upgraded two Y-shaped one-way piston seal for longer life.
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 push at 0.9 MPa, with a theoretical max of 3204 kgf at 1.0 MPa. The external stop screw provides a 20 mm adjust window, allowing you to trim the 80 mm nominal extend stroke down to 60 mm on-site. The stop sets end position and is not a load lock.
