This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X1000-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X1000-20 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 SIJ80X1000-20
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-20 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 SAIJ80X1000-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-20
The AirTAC SIJ80X1000-20 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and superseded by the drop-in SAIJ80X1000-20. It features an 80mm bore, a maximum 1000mm stroke, and a G3/8 port. The external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 980-1000mm extend window. This stop sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.
Force output matches the standard single-rod SAI figures: 2513N push and 2268N pull at 0.5MPa, reaching 4523N at 0.9MPa. The upgraded SAIJ replacement employs a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508N (60% of the 0.5MPa push), equating to a 128kg vertical lift with a 2:1 margin. This SKU lacks a -S magnet and cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X1000-20 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 SAIJ80X1000-20 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 SIJ80X1000-20 Is Used
Transfer Line Diverter
Needs field stroke tuning to dial in the exact 980-1000mm extend reach for a pallet diverter without machining a new stop.
Long-Press Forming
Requires trimming the extend stroke by up to 20mm on-site to set the precise final forming position on a 1000mm press bed.
Depalletizer Arm
Demands an adjustable end position to account for varying pallet heights, using the external stop screw to set the exact extend limit.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-20 with the SAIJ80X1000-20
To replace the discontinued SIJ80X1000-20, order the exact drop-in SAIJ80X1000-20, reusing your existing ISO 15552 FA, LB, or TC mounting hardware. The 20mm adjust window lets you fine-tune the extend end position from 980 to 1000mm on-site. If you need to size both ways, the neighbouring 63mm bore yields 2182N push at 0.7MPa, while the 100mm bore yields 5497N push at 0.7MPa. Because this is a 1000mm long stroke, verify external guides to prevent rod bending and side-load damage. Note this non-magnetic SKU cannot accept a legacy CS1-B or DS1-B sensor.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1000-20
- ✓ 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 SIJ80X1000-20 FAQ
Yes, the SIJ80X1000-20 is discontinued. The exact drop-in replacement is the SAIJ80X1000-20, offering the same ISO 15552 interface, 80mm bore, 1000mm stroke, 20mm adjust window, G3/8 port, and mounting options.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa. The external stop screw window is 20mm, allowing you to shorten the 1000mm extend stroke to 980mm on-site. The stop sets end position but is not a load lock.
