This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-100SFA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-100SFA 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 SIJ80X160-100SFA
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100SFA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X160-100SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100SFA
The AirTAC SIJ80X160-100SFA 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 100 mm on-site, yielding a usable 60-160 mm extension out of the 160 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 rod thread, 36 mm adjustable cushions, a G3/8 port, and an FA mount.
This EOL model drops directly into the SAIJ80X160-100SFA replacement, retaining the exact ISO 15552 interface, bore, force, adjust window, and porting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Based on the 0.5 MPa push force, the computed safe working load is roughly 1508 N (60% of 2513 N), translating to a vertical lift capacity of about 128 kg with a 2:1 margin. Note the stop screw sets the end position; it is not a lock, and a plain cylinder drifts on air loss, so use an external rod lock or SAIL/BSAI variant for held loads.

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 SAIJ80X160-100SFA 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 SIJ80X160-100SFA Is Used
Variable Depth Spot Facing
Machine operators trim the extend stroke by up to 100 mm on-site to hit changing casting depths without swapping the entire cylinder.
Adjustable Transfer Pusher
A packaging line dials the 160 mm stroke back to push varying box widths, using the external stop screw to set the exact end position.
Tiered Pallet Stops
Logistics conveyors utilize the 60-160 mm usable extend window to create multiple physical stop positions for different pallet heights.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100SFA with the SAIJ80X160-100SFA
To replace the discontinued SIJ80X160-100SFA, map directly to the SAIJ80X160-100SFA, keeping the 160 mm nominal stroke, 100 mm adjust window, FA mount, and -S magnet for legacy CS1-B/DS1-B switches. When sizing both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa; hold the 80 mm bore if you need its 3518 N push at 0.7 MPa. Choose the 100 mm adjust window when your assembly requires field tuning the extend stroke down to 60 mm. The FA foot mount interfaces with ISO 15552 dimensions. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-100SFA
- ✓ 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 SIJ80X160-100SFA FAQ
Yes, the SIJ80X160-100SFA is discontinued. The exact drop-in replacement is the SAIJ80X160-100SFA, which shares the identical ISO 15552 interface, 80 mm bore, 160 mm stroke, 100 mm adjust window, G3/8 port, and FA mounting.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a max of 513 kgf at 1.0 MPa. The external stop screw window is 100 mm, allowing an extend stroke range of 60-160 mm. The stop sets end position but is not a load lock.
