This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-40S 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 SIJ80X100-40S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X100-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-40S
The AirTAC SIJ80X100-40S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 100 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 60-100 mm window. The exact drop-in replacement is the SAIJ80X100-40S, matching the G3/8 port, M20x1.5 rod thread, and 36 mm cushions. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, rising to 4523 N at 0.9 MPa.
The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. Computed buyer insight: 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. Upgrading to SAIJ brings a two-piece Y-shaped piston seal for lower start-up pressure, and the SAI family adds SAIF valve and lock variants the SI line lacked.

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 SAIJ80X100-40S 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 SIJ80X100-40S Is Used
Press Fit Tuning
Adjusting the extend stroke on-site by up to 40 mm allows precise press-fit depth without machining custom spacers.
Variable Transfer Stops
Trimming the 100 mm extend stroke lets a single actuator adapt to varying package sizes on a ISO 15552 conveyor line.
Pallet Positioning
Field tuning the extend end position accommodates different pallet widths while maintaining 2513 N push force at 0.5 MPa.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-40S with the SAIJ80X100-40S
To replace the discontinued SIJ80X100-40S, order the drop-in SAIJ80X100-40S, reusing your existing ISO 15552 FA, LB, or TC mounts. Size both ways by force: the 63 mm neighbor gives 1559 N push at 0.5 MPa, while the 100 mm bore gives 3927 N. Select the 40 mm adjust window if you need to trim the extend stroke on-site; the external stop sets end position but does not lock the load. The -S suffix provides a piston magnet for CS1-B/DS1-B switches. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-40S
- ✓ 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 SIJ80X100-40S FAQ
Yes, the SIJ80X100-40S is discontinued. The exact drop-in replacement is the SAIJ80X100-40S, offering the same ISO 15552 interface, 80 mm bore, 100 mm stroke, 40 mm adjust window, and G3/8 port.
