This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X950-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X950-100 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 SIJ80X950-100
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X950-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 950mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X950-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X950-100
The AirTAC SIJ80X950-100 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and a 950 mm maximum extend stroke. An external stop screw lets you trim the extend stroke on-site by up to 100 mm, yielding a usable 850-950 mm window. It delivers 2513 N push and 2268 N pull at 0.5 MPa, features a Ø25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a G3/8 port. The drop-in replacement is the SAIJ80X950-100, sharing the exact interface, force, and mounting.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Computed buyer insight: safe working load is ~1508 N (60% of the 2513 N push @0.5 MPa), giving a ~128 kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot take a switch. The stop screw sets 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 SAIJ80X950-100 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 SAIJ80X950-100 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 SIJ80X950-100 Is Used
Variable-Length Pressing
Tuning a 850-950 mm pressing stroke on-site to accommodate different material thicknesses without changing the cylinder body.
Adjustable Transfer Pusher
Setting precise push-off distances for varying pallet sizes on a long conveyor line using the 100 mm stop-screw window.
Multi-Position Diverting
Field-adjusting the extend endpoint to divert packages of differing depths into specific sorting lanes.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X950-100 with the SAIJ80X950-100
To replace the discontinued SIJ80X950-100, order the drop-in SAIJ80X950-100, reusing your FA, LB, or TC ISO 15552 mounts. The 100 mm adjust window lets you tune the extend from 850 to 950 mm on-site. If sizing both ways: the 63 mm bore yields 1559 N push @0.5 MPa, while the 100 mm bore yields 3927 N. Because the 950 mm stroke invites rod bending, ensure external guides to minimize side-load. This SKU lacks the -S magnet, so it cannot support legacy CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X950-100
- ✓ 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 SIJ80X950-100 FAQ
Yes, the SIJ80X950-100 is discontinued. The exact drop-in replacement is the SAIJ80X950-100. It shares the same ISO 15552 interface, 80 mm bore, 950 mm stroke, 100 mm adjust window, G3/8 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull @0.5 MPa, 3518 N push @0.7 MPa, and 4523 N push @0.9 MPa (513 kgf max @1.0 MPa). The external stop screw provides a 100 mm adjustment window, allowing the 950 mm extend stroke to be shortened to 850 mm. The stop sets end position only; it is not a load lock.
