This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X75-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X75-10 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 SIJ80X75-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 75mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X75-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-10
The AirTAC SIJ80X75-10 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and a 75 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 65-75 mm stroke window. The stop screw strictly sets the end position; it is not a load lock, and a plain cylinder cannot hold a load on air loss. This SKU has no -S magnet and cannot accept a magnetic switch.
The exact drop-in replacement is the SAIJ80X75-10, sharing the same ISO 15552 mounting interface, G3/8 port, and 2513 N push force at 0.5 MPa. The SAIJ upgrade uses a two Y-shaped one-way piston seal 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 force), translating to a 128 kg vertical lift with a 2:1 margin. The SAI family also adds lock variants (SAIL, BSAI) the SI line lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X75-10 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 SAIJ80X75-10 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 SIJ80X75-10 Is Used
Short-Stroke Clamping
Provides 65-75 mm clamping travel where a fixed 75 mm unit would over-travel, allowing precise on-site end-position tuning for varied part heights.
Transfer Diverter Setup
Adjusts the extend endpoint by up to 10 mm to fine-tune a diverting gate without swapping the entire cylinder or adding external mechanical spacers.
Carton Sealing Press
Dials in the exact 65-75 mm downstroke needed for varying package thicknesses, ensuring consistent sealing pressure without reprogramming the machine.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-10 with the SAIJ80X75-10
To replace the discontinued SIJ80X75-10, order the drop-in SAIJ80X75-10, which preserves the 75 mm nominal stroke, 10 mm adjust window, G3/8 port, and FA/LB/TC mountings. When 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 based on your exact force requirement. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors. The external stop screw sets the end position but is not a lock; for load holding on air loss, use an external rod lock or pilot-operated check valve. Since the stroke is under 300 mm, side-load lever arm risks are minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X75-10
- ✓ 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 SIJ80X75-10 FAQ
Yes, the SIJ80X75-10 is discontinued. The exact drop-in replacement is the SAIJ80X75-10. It shares the same ISO 15552 interface, 80 mm bore, 75 mm stroke, 10 mm adjust window, G3/8 port, and mounting options. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a 513 kgf max at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing you to trim the 75 mm nominal extend stroke down to 65 mm on-site. The stop sets end position only; it is not a load lock.
