This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X25-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X25-30 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 SIJ80X25-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X25-30 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 SAIJ80X25-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X25-30
The AirTAC SIJ80X25-30 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 25 mm nominal extend stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 0-25 mm window. This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, running at 30-800 mm/s with 36 mm adjustable cushions. The stop sets the end position but is not a load lock.
The exact drop-in replacement is the SAIJ80X25-30, retaining the interface, force, and mounting. The SAIJ family uses an upgraded two Y-shaped one-way piston seal for low start-up pressure. Based on the 0.5 MPa push rating, the safe working load is roughly 1508 N (60% of 2513 N), translating to a 128 kg vertical lift with a 2:1 margin. This SKU lacks a -S magnet and cannot take a switch; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X25-30 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 SAIJ80X25-30 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 SIJ80X25-30 Is Used
Short-Stroke Clamping
Tuning the 0-25 mm extend contact point on machining fixtures to clamp variable part thicknesses without re-plumbing the G3/8 air lines.
Transfer Diverter Setup
Adjusting the extend stop on-site to set the exact diverter finger position for different package widths on a packaging line.
Pallet Stop Positioning
Fine-tuning the end stop height or depth in pallet handling modules where the nominal 25 mm stroke needs minor field adjustment for pallet variance.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X25-30 with the SAIJ80X25-30
To replace the discontinued SIJ80X25-30, order the drop-in SAIJ80X25-30, matching the 80 mm bore, 25 mm stroke, and 30 mm adjust window. 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. The 30 mm adjust window allows on-site tuning of the extend end position, but remember the stop is not a lock. Mounting reuses ISO 15552 basic, FA, LB, or TC interfaces. Because this SKU has no -S magnet, it cannot accept a sensor. For strokes >=300 mm, verify side-load tolerance. A plain cylinder drifts on air loss; for held loads use an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X25-30
- ✓ 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 SIJ80X25-30 FAQ
Yes, the SIJ80X25-30 is discontinued. The exact drop-in replacement is the SAIJ80X25-30, which shares the same ISO 15552 interface, 80 mm bore, 25 mm stroke, 30 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded 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, 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 30 mm on-site (usable 0-25 mm). The stop sets end position and is not a load lock.
