This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X25-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X25-10 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 SIJ80X25-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X25-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 25mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X25-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X25-10
The AirTAC SIJ80X25-10 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and 25 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 15-25 mm extend window. This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, features a 36 mm adjustable air cushion, and uses a fixed G3/8 port. This SIJ model is discontinued; the exact drop-in replacement is the SAIJ80X25-10, matching the interface, force, and mounting.
The SAIJ upgrade incorporates an improved piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, 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. Note this SKU lacks a -S magnet and cannot accept a sensor. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X25-10 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 SAIJ80X25-10 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 SIJ80X25-10 Is Used
Short-Stroke Clamping
Adjustable end-position clamping of varied parts where a fixed 25 mm stroke is excessive, letting operators trim the extend by up to 10 mm on-site.
Transfer Diverter
Actuating a diverter gate on a conveyor line where the exact 15-25 mm extend reach must be dialed in to match product dimensions without repositioning the cylinder.
Light Press Fit
Performing low-force press operations where the 2513 N push at 0.5 MPa is sufficient and the 10 mm stop screw allows precise depth control for delicate inserts.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X25-10 with the SAIJ80X25-10
To replace the discontinued SIJ80X25-10, order the drop-in SAIJ80X25-10, which preserves the 80 mm bore, 25 mm stroke, 10 mm adjust window, and G3/8 port. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N push; this 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. Choose the 10 mm adjust window if your application requires fine-tuning the extend stroke down to a 15 mm minimum. Mounting options include Basic, FA, LB, and TC interfaces. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. Since the 25 mm stroke is under 300 mm, side-load risks are minimal. Remember the stop screw is not a lock; for load holding without live air, use an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X25-10
- ✓ 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 SIJ80X25-10 FAQ
Yes, the AirTAC SIJ80X25-10 is discontinued. The exact drop-in replacement is the SAIJ80X25-10, which shares the identical ISO 15552 interface, 80 mm bore, 25 mm nominal stroke, 10 mm adjust window, G3/8 port, and mounting options.
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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 10 mm on-site, giving a usable extend window of 15-25 mm. The stop sets end position and is not a load lock.
