This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X35-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X35-10S 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 SIJ80X35-10S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X35-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 35mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X35-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X35-10S
The AirTAC SIJ80X35-10S 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 10 mm on-site, giving a usable 25-35 mm window (35 mm nominal maximum). It features a Ø25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, a G3/8 port, and speeds of 30-800 mm/s. The exact drop-in replacement is the SAIJ80X35-10S, matching the interface, bore, force, and mountings.
At 0.5 MPa it delivers 2513 N push and 2268 N pull (3518 N @0.7 MPa; 4523 N @0.9 MPa). A computed buyer insight: safe working load is ~1508 N (60% of the 0.5 MPa push), yielding a ~128 kg vertical lift with a 2:1 margin. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure. The stop sets end position but is not a load lock; for held loads use SAIL or BSAI.

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 SAIJ80X35-10S 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 SIJ80X35-10S Is Used
Short-Stroke Clamping
Tune the exact 25-35 mm extend reach on-site to clamp varying workpiece thicknesses without changing the cylinder body.
Transfer Diverter
Adjust the stop screw to set the precise extension length for a diverter gate, allowing quick field changes to product flow.
Pallet Stopper
Trim the extend stroke by up to 10 mm to act as a fixed-height pallet stop, accommodating different pallet profiles on the line.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X35-10S with the SAIJ80X35-10S
To replace the discontinued SIJ80X35-10S, use the drop-in SAIJ80X35-10S (insert A after S), retaining the -S magnet for CS1-B/DS1-B switches. Size both ways: the 63 mm neighbor gives 1559 N push @0.5 MPa, while the 100 mm bore gives 3927 N. Choose the 10 mm adjust window if you need to tune the extend stroke on-site (25-35 mm range). Mounting uses Basic, FA, LB, or TC via the ISO 15552 interface. Note: stroke is under 300 mm, so side-load risks are minimal. The stop screw sets end position; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X35-10S
- ✓ 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 SIJ80X35-10S FAQ
Yes, the SIJ80X35-10S is discontinued. The exact drop-in replacement is the SAIJ80X35-10S, offering the same ISO 15552 interface, 80 mm bore, 35 mm stroke, 10 mm adjust window, G3/8 port, and mounting options. The SAIJ uses an upgraded two Y-shaped one-way piston seal for longer life.
The 80 mm bore delivers 2513 N push and 2268 N pull @0.5 MPa, 3518 N @0.7 MPa, and 4523 N @0.9 MPa (max 513 kgf @1.0 MPa). The external stop screw provides a 10 mm adjust window, allowing you to shorten the extend stroke from the 35 mm maximum down to 25 mm on-site. The stop sets end position and is not a load lock.
