This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X225-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X225-20S 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 SIJ80X225-20S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X225-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20S
The AirTAC SIJ80X225-20S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, officially discontinued and replaced by the SAIJ80X225-20S. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, giving a usable 205-225 mm window (the 225 mm nominal stroke is the maximum). The 80 mm bore uses a G3/8 port, a 25 mm rod, and delivers 2513 N push / 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa.
The drop-in SAIJ replacement retains the exact ISO 15552 mounting interface, force, and adjust window, while upgrading to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Computed buyer insight: 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 stop screw sets the end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X225-20S 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 SAIJ80X225-20S 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 SIJ80X225-20S Is Used
Variable Stroke Forming
Allows precise 205-225 mm extend tuning for pressing or forming tasks where material thickness varies, using the external stop screw to set the exact end position.
Adjustable Transfer Pusher
Enables on-site stroke trimming for diverter arms pushing different package sizes, ensuring items reach the correct transfer point without re-mounting hardware.
Tunable End-Stop Diverter
Provides a field-adjustable end position for sorting gates, allowing operators to quickly shorten the extend stroke by up to 20 mm to accommodate new product dimensions.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20S with the SAIJ80X225-20S
To replace the discontinued SIJ80X225-20S, order the drop-in SAIJ80X225-20S, which keeps the 225 mm stroke, 20 mm adjust window, G3/8 port, and 2513 N push @0.5 MPa. When sizing both ways, the neighbouring 63 mm bore yields 1559 N push @0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 20 mm adjust window if you need precise 205-225 mm extend tuning on-site; a fixed SAI with an external stop lacks this integrated trim. Mounting options include Basic, FA, LB, and TC. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For strokes >=300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X225-20S
- ✓ 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 SIJ80X225-20S FAQ
Yes, the SIJ80X225-20S is discontinued. The exact drop-in replacement is the SAIJ80X225-20S, which shares the same ISO 15552 interface, 80 mm bore, 225 mm stroke, 20 mm adjust window, G3/8 port, and mounting options.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N at 0.9 MPa. The external stop screw provides a 20 mm adjust window, allowing the extend stroke to be shortened from the 225 mm maximum down to 205 mm on-site.
