This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X300-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X300-10S 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 SIJ80X300-10S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X300-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 300mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X300-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X300-10S
The AirTAC SIJ80X300-10S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 300 mm nominal stroke and a built-in piston magnet. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 290-300 mm stroke window. The stop sets the end position; it is not a load lock, as a plain cylinder drifts on air loss. This 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions. It delivers 2513 N push and 2268 N pull at 0.5 MPa.
The exact drop-in replacement is the SAIJ80X300-10S, matching the ISO 15552 interface, bore, force, and mounting. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long 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. The SAI family also adds lock variants like SAIL and BSAI that the SI line lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X300-10S 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 SAIJ80X300-10S 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 SIJ80X300-10S Is Used
Press Fit Calibration
Trimming the extend stroke by up to 10 mm on-site allows precise lower-dwell tuning for a 128 kg press fit without machining hard stops.
Transfer Pusher Adjustment
A 290-300 mm extend window accommodates varying pallet thicknesses on a transfer line, letting operators dial in the final push position quickly.
Pallet Stop Positioning
External stop screw adjustment sets the exact 300 mm end position for pallet stops, ensuring repeatable locating without reprogramming the machine.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X300-10S with the SAIJ80X300-10S
To replace the discontinued SIJ80X300-10S, order the drop-in SAIJ80X300-10S, reusing your existing FA, LB, or TC ISO 15552 mounts. The 10 mm adjust window is ideal for final end-position tuning rather than large stroke changes. If sizing both ways, the neighbouring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches; the SAIJ uses current AirTAC switches. For the 300 mm stroke, use external guides to prevent rod bending and manage side loads. The stop screw sets position but does not hold loads on air loss; for held loads use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X300-10S
- ✓ 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 SIJ80X300-10S FAQ
Yes, the SIJ80X300-10S is discontinued. The exact drop-in replacement is the SAIJ80X300-10S. It shares the identical ISO 15552 interface, 80 mm bore, 300 mm stroke, 10 mm adjust window, G3/8 port, and mounting, but adds 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 window is 10 mm, allowing you to shorten the 300 mm extend stroke down to 290 mm on-site. The stop sets end position and is not a load lock.
