This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-100S 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 SIJ80X160-100S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100S 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 SAIJ80X160-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100S
The AirTAC SIJ80X160-100S 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, giving a usable 60-160 mm extension out of the 160 mm nominal maximum. The Ø80 mm bore features a Ø25 mm rod, M20x1.5 thread, G3/8 port, and 36 mm adjustable air cushions. It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N push at 0.9 MPa.
Because this SIJ model is end-of-life, the exact drop-in replacement is the SAIJ80X160-100S, retaining the same interface, force, port, and mounting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. A computed buyer insight: the safe working load is roughly 1508 N (60% of the 2513 N push at 0.5 MPa), yielding a 128 kg vertical lift capacity with a 2:1 safety margin. The stop screw sets the end position but is not a load lock; for held loads use SAIL, BSAI, or an external rod lock.

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 SAIJ80X160-100S 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 SIJ80X160-100S Is Used
Variable Depth Forming
Adjusts the extend stroke on-site for pressing or forming operations where material thickness varies, using the 100 mm window to alter the end position without changing cylinders.
Adjustable Transfer Pusher
Tunes the pusher extension length precisely to the product width on a packaging line, trimming the extend stroke by up to 100 mm to accommodate different carton sizes.
Dynamic Sorting Diverter
Modifies the divert stroke distance on the fly for sorting mixed parcel depths, using the external stop screw to set the exact 60 to 160 mm extend position required.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100S with the SAIJ80X160-100S
To replace the discontinued SIJ80X160-100S, order the drop-in SAIJ80X160-100S, which preserves the ISO 15552 mounting dimensions, G3/8 port, and 100 mm adjust window. When sizing both ways, the neighboring 63 mm bore provides 1559 N push at 0.5 MPa, while the 100 mm bore offers 3927 N push at 0.5 MPa. Choose the 100 mm adjust window if your setup requires trimming the 160 mm nominal extend down to a 60 mm minimum. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. For stroke lengths of 300 mm or more, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-100S
- ✓ 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 SIJ80X160-100S FAQ
Yes, the SIJ80X160-100S is discontinued. The exact drop-in replacement is the SAIJ80X160-100S. It shares the same ISO 15552 interface, 80 mm bore, 160 mm stroke, 100 mm adjust window, G3/8 port, and mounting options, while adding an upgraded piston seal.
The full force set is 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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 100 mm adjust window, allowing you to shorten the 160 mm nominal extend stroke down to 60 mm on-site. The stop sets end position and is not a load lock.
