This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X1000-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X1000-40S 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 SIJ80X1000-40S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X1000-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-40S
The AirTAC SIJ80X1000-40S 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 40 mm on-site, giving a usable range of 960-1000 mm. It features a 25 mm rod, M20x1.5 thread, G3/8 port, and 36 mm adjustable cushions. The drop-in replacement is the SAIJ80X1000-40S, matching the interface, force, and port.
At 80 mm bore, thrust is 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. The computed safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift with a 2:1 margin. The SAIJ upgrade uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Note the stop sets end position but is not a load lock; use SAIL or BSAI for holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X1000-40S 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 SAIJ80X1000-40S 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 SIJ80X1000-40S Is Used
Long-stroke press ejection
Uses the 1000 mm extend to reach deep into a press bed, then dials back the stop screw by 40 mm to tune the ejection point precisely for varying mold depths.
Variable-length pallet stops
Acts as a pneumatic stop gate on a conveyor where pallet lengths vary, using the 960-1000 mm adjustable window to set the exact physical end-position barrier on-site.
Telescopic ram extension
Provides a long 1000 mm reach for actuating telescopic mechanisms or heavy doors, allowing a 40 mm trim to compensate for mechanical tolerance stack-up without adding spacers.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-40S with the SAIJ80X1000-40S
To replace the discontinued SIJ80X1000-40S, order the drop-in SAIJ80X1000-40S, which retains the G3/8 port, 25 mm rod, and ISO 15552 mounting. For sizing both ways: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. The 40 mm adjust window is ideal for field-tuning the extend end position without machining. Mounting includes FA, LB, and TC brackets. The -S suffix includes a piston magnet for legacy CS1-B/DS1-B switches. Because the 1000 mm stroke is long, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1000-40S
- ✓ 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 SIJ80X1000-40S FAQ
Yes, the SIJ80X1000-40S is discontinued. The exact drop-in replacement is the SAIJ80X1000-40S. It shares the identical ISO 15552 interface, 80 mm bore, 1000 mm max stroke, 40 mm adjust window, G3/8 port, and 25 mm rod. The SAIJ family also features an upgraded piston seal and adds lock variants like SAIL and BSAI.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa (max 513 kgf at 1.0 MPa). The external stop screw provides a 40 mm adjustable window, making the usable extend stroke 960-1000 mm. The stop only sets the end position; it is not a load lock.
