This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X20-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X20-10S 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 SIJ80X20-10S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X20-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 20mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X20-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X20-10S
The AirTAC SIJ80X20-10S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 20 mm maximum extend stroke and a 10 mm on-site trim window. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, setting the exact end position. This 80 mm bore features a Ø25 mm piston rod, M20x1.5 rod-end thread, G3/8 air port, and 36 mm adjustable air cushions at each end. It delivers 2513 N push and 2268 N pull at 0.5 MPa, with a 4523 N push at 0.9 MPa. The exact drop-in replacement is the SAIJ80X20-10S, sharing the same ISO 15552 mounting interface, force, and porting.
The SAIJ replacement retains the physical interface but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Computed buyer insight: the safe working load is roughly 1508 N (60% of the 2513 N push at 0.5 MPa), yielding a vertical lift capacity of about 128 kg with a 2:1 margin. The external stop screw sets end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or the SAIL/BSAI lock variant for held loads. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X20-10S Is Used
Short-Stroke Clamping
Ideal for clamping parts where the exact 10 to 20 mm extend position must be tuned on-site to accommodate material thickness variations without changing the cylinder body.
Transfer Stopper Fingers
Deployed as an adjustable stop finger on a conveyor line, allowing technicians to trim the extend stroke by up to 10 mm to align with varying product widths.
Compact Ejector Pins
Used in tight machinery ejector setups where a 20 mm maximum stroke is required, but a 10 mm external screw adjustment is needed to dial in the precise ejection distance.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X20-10S with the SAIJ80X20-10S
To replace the discontinued SIJ80X20-10S, order the drop-in SAIJ80X20-10S, which preserves the G3/8 port, 20 mm nominal stroke, and 10 mm adjust window. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N push at 0.5 MPa; this 80 mm bore provides 2513 N push at 0.5 MPa. Select the 10 mm adjust window if you need to fine-tune the extend stroke between 10 and 20 mm on-site. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix confirms the piston magnet is present for switch sensing. Because the 20 mm stroke is well under 300 mm, side-load rod deflection is negligible. Operating speed is 30-800 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X20-10S
- ✓ 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 SIJ80X20-10S FAQ
Yes, the SIJ80X20-10S is discontinued. The exact drop-in replacement is the SAIJ80X20-10S. It shares the same ISO 15552 interface, 80 mm bore, 20 mm stroke, 10 mm adjust window, G3/8 port, and mounting options, but features an upgraded piston seal.
The 80 mm bore delivers 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 10 mm adjust window, allowing you to shorten the 20 mm extend stroke down to 10 mm on-site. The stop sets end position and is not a load lock.
