This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X1400-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X1400-40S 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 SIJ80X1400-40S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1400-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1400mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X1400-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1400-40S
The AirTAC SIJ80X1400-40S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw trims the extend stroke by up to 40 mm on-site, yielding a usable 1360-1400 mm range. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, with a G3/8 port and M20x1.5 rod thread. The exact drop-in replacement is the SAIJ80X1400-40S, sharing the same interface, force, and mounting.
The SAIJ upgrade uses an upgraded two-piece Y-shaped piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is ~1508 N (60% of the 0.5 MPa push), offering a 128 kg vertical lift with a 2:1 margin. The stop sets end position only; it is not a load lock. For held loads, use an external rod lock or SAIL/BSAI variant. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X1400-40S 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 SAIJ80X1400-40S 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 SIJ80X1400-40S Is Used
Variable Press Stroke
Trimming the extend endpoint by up to 40 mm on-site allows precise positioning of a press head without machining spacers.
Adjustable Transfer Pusher
Tuning the push-off distance on a long 1400 mm transfer line accommodates varying package widths on the fly.
Variable Height Diverter
Setting the exact extend stop position lets a diverter gate handle different pallet profiles accurately.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1400-40S with the SAIJ80X1400-40S
To replace the discontinued SIJ80X1400-40S, order the drop-in SAIJ80X1400-40S, reusing your existing ISO 15552 FA, LB, or TC mounts. When sizing both ways, the 63 mm neighbor yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 40 mm adjust window if your extend endpoint needs on-site tuning between 1360 and 1400 mm. The -S magnet ensures position detection. Because the 1400 mm stroke exceeds 300 mm, support the rod against side-load bending and use external guides to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1400-40S
- ✓ 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 SIJ80X1400-40S FAQ
Yes, the SIJ80X1400-40S is discontinued. The exact drop-in replacement is the SAIJ80X1400-40S, which shares the same ISO 15552 interface, 80 mm bore, 1400 mm stroke, 40 mm adjust window, G3/8 port, and mounting options.
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. The external stop screw offers a 40 mm adjust window, shortening the extend stroke from the 1400 mm maximum down to 1360 mm. The stop sets end position and is not a load lock.
