This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X125-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X125-30S 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 SIJ80X125-30S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X125-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 125mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X125-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X125-30S
The AirTAC SIJ80X125-30S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 95-125 mm range from the 125 mm nominal maximum. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. It features a Ø25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a fixed G3/8 port. The exact drop-in replacement is the SAIJ80X125-30S, matching the ISO 15552 mounting interface, bore, force, and adjust window.
The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, the 2513 N push at 0.5 MPa yields a safe working load of roughly 1508 N (60%), or a 128 kg vertical lift with a 2:1 margin. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note the stop screw sets end position only; it is not a load lock. For held loads, use an external rod lock or the SAIL/BSAI variants.

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 SAIJ80X125-30S 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 SIJ80X125-30S Is Used
Press Fit Tuning
Allows on-site extend stroke reduction by up to 30 mm to dial in exact press-fit depths without machining new hard stops.
Variable Length Diverter
Adjusts the extend endpoint on the fly to accommodate different package lengths on a sorting line.
Adjustable End Stop
Sets precise 95-125 mm extend positions for varying pallet sizes while maintaining ISO 15552 mounting compatibility.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X125-30S with the SAIJ80X125-30S
To replace the discontinued SIJ80X125-30S, specify the SAIJ80X125-30S drop-in: it preserves the 80 mm bore, 125 mm nominal stroke, 30 mm adjust window, G3/8 port, and ISO 15552 mounting. Size both ways using 0.5 MPa force: the 63 mm bore yields 1559 N push, while the 100 mm bore yields 3927 N push. Choose the 30 mm adjust window when you need field tuning of the extend stroke within a 95-125 mm range. Mounting options include Basic, FA, LB, and TC. The -S suffix provides a piston magnet for position sensing. For strokes at or above 300 mm, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X125-30S
- ✓ 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 SIJ80X125-30S FAQ
