This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X200-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X200-40S 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X200-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40S
The AirTAC SIJ80X200-40S 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 40 mm on-site, giving a usable 160-200 mm window from the 200 mm nominal maximum. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions, yielding 2513 N push and 2268 N pull at 0.5 MPa. The exact drop-in replacement is the SAIJ80X200-40S, retaining the same interface, force, and mounting.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is roughly 1508 N (60% of the 0.5 MPa push), allowing a 128 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; for held loads use SAIL/BSAI or an external rod lock.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X200-40S 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40S Is Used
Variable Stroke Pressing
Dial in the exact 160-200 mm extend position on-site to press components of varying heights without re-engineering the fixture.
Adjustable Diverters
Tune the extend stop to accommodate different package widths on a line, ensuring the rod end meets the exact product profile.
Variable Depth Stops
Set precise mechanical end positions for pallets of varying depths, relying on the external stop screw for repeatable physical limits.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40S with the SAIJ80X200-40S
To replace the discontinued SIJ80X200-40S, specify SAIJ80X200-40S directly—the bore, 200 mm stroke, 40 mm adjust window, G3/8 port, and FA/LB/TC mountings carry over. For sizing both ways: the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 40 mm adjust window if your extend stroke needs on-site tuning between 160 and 200 mm. The -S suffix provides a piston magnet for CS1-B/DS1-B switches. For stroke lengths >=300 mm, verify side-load guidance to prevent rod wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-40S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40S FAQ
Yes, the SIJ80X200-40S is discontinued. The exact drop-in replacement is the SAIJ80X200-40S. It shares the identical ISO 15552 interface, 80 mm bore, 200 mm stroke, 40 mm adjust window, G3/8 port, and mounting options, but adds an upgraded piston seal.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The external stop screw provides a 40 mm adjust window, allowing you to shorten the 200 mm extend stroke down to 160 mm on-site. The stop sets end position and is not a load lock.
