This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-20S 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X160-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20S
The AirTAC SIJ80X160-20S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 160 mm nominal stroke and a built-in piston magnet. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 140-160 mm window. The exact drop-in replacement is the SAIJ80X160-20S, matching the 80 mm bore, G3/8 port, M20x1.5 rod thread, and 36 mm cushions. The stop sets end position only; it is not a load lock.
At 0.5 MPa this bore pushes 2513 N and pulls 2268 N, reaching 4523 N at 0.9 MPa. A safe working load is roughly 1508 N (60% of the 0.5 MPa push), equating to a 128 kg vertical lift with a 2:1 margin. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure, and adds SAIL/BSAI lock variants the SI line lacked. Without live air the piston drifts; cushions only decelerate near stroke end.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X160-20S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAIJ80X160-20S 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20S Is Used
Variable Press Stroke
Trimming the extend stroke by up to 20 mm on-site allows precise positioning of a pressing head without machining custom spacers.
Adjustable Diverter Arm
Tuning the 160 mm extend window lets operators alter the divert path angle on a conveyor line to accommodate varying package widths.
End-Stop Calibration
Setting the final end position externally via the stop screw simplifies calibrating a pallet stop gate during installation.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20S with the SAIJ80X160-20S
Replace the discontinued SIJ80X160-20S directly with the SAIJ80X160-20S, reusing your existing ISO 15552 FA, LB, or TC mounts. To size both ways: the 63 mm neighbor pushes 1559 N at 0.5 MPa, while the 100 mm bore pushes 3927 N. The 20 mm adjust window is ideal if your extend target needs final on-site tuning between 140 and 160 mm. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For stroke lengths >=300 mm, verify the rod-end side-load limits. Because the stop screw is not a lock and the cylinder drifts without live air, use an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-20S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20S FAQ
Yes, the SIJ80X160-20S is discontinued. The exact drop-in replacement is the SAIJ80X160-20S, which shares the same ISO 15552 interface, 80 mm bore, 160 mm stroke, 20 mm adjust window, G3/8 port, and mounting options. The SAIJ features an upgraded two Y-shaped one-way piston seal.
The 80 mm bore provides 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 (max 513 kgf at 1.0 MPa). The external stop screw shortens the extend stroke by up to 20 mm, giving a usable 140-160 mm window. The stop sets end position and is not a load lock; speed is 30-800 mm/s.
