This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X600-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X600-100S 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 SIJ80X600-100S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X600-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-100S
The AirTAC SIJ80X600-100S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 500-600 mm extension from the 600 mm nominal maximum. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 thread, G3/8 port, and 36 mm adjustable cushions. The exact drop-in replacement is the SAIJ80X600-100S, matching the interface, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting dimensions but uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B sensors. Note that the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X600-100S 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 SAIJ80X600-100S 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 SIJ80X600-100S Is Used
Variable Pitch Forming
Sheet metal lines needing field stroke tuning to alter bend depths without swapping cylinders, using the 100 mm adjust window to dial in the exact 500-600 mm extend position.
Adjustable Transfer Pushers
Packaging conveyors where product lengths change frequently, allowing operators to shorten the extend stroke on-site to accommodate varied box sizes.
Multi-Position Diverters
Warehouse sorting gates requiring precise physical end-stop positioning at different points along the 600 mm travel without complex multi-position valve setups.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-100S with the SAIJ80X600-100S
To replace the discontinued SIJ80X600-100S, order the exact drop-in SAIJ80X600-100S, which preserves the G3/8 port, 25 mm rod, and 100 mm adjust window. When sizing both ways, the neighbouring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore provides 5497 N push at 0.7 MPa. Choose the 100 mm adjust window if your setup requires trimming up to 100 mm off the 600 mm nominal extend; for smaller trims, select a narrower window to minimize screw overhang. Reuse FA, LB, or TC mounts directly via the ISO 15552 interface. The -S suffix ensures a piston magnet is present for switch sensing. Because the 600 mm stroke exceeds 300 mm, verify side-load limits and use external guides to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-100S
- ✓ 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 SIJ80X600-100S FAQ
Yes, the SIJ80X600-100S is discontinued. The exact drop-in replacement is the SAIJ80X600-100S. It shares the same ISO 15552 interface, 80 mm bore, 600 mm nominal stroke, 100 mm adjust window, G3/8 port, and mounting options, but features an upgraded piston seal.
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 allows you to trim the extend stroke by up to 100 mm on-site, giving a usable 500-600 mm stroke. The stop sets end position and is not a load lock.
