This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-30SN — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-30SN 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.

The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-30SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X100-30SN, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X100-30SL is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 100 mm nominal stroke and a 30 mm on-site extend-trim window, yielding a usable extend range of 70-100 mm. The external stop screw sets the end position but is not a load lock. It delivers 2513 N push and 2268 N pull at 0.5 MPa, features a G3/8 port, and includes the -S magnet and -N NBR seals (-20 to +70 C). The exact drop-in replacement is the SAIJ80X100-30SL.
The SAIJ successor reuses the same ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Computed buyer insight: safe working load is ~1508 N (60% of the 2513 N push), allowing a ~128 kg vertical lift with a 2:1 margin. A plain cylinder drifts on air loss; use an external rod lock or SAIL/BSAI variant for held loads.

The SAIJ80X100-30SN 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.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Trimming the extend stroke by up to 30 mm on-site allows a 80 mm bore actuator to adapt drill depth precisely without changing the entire cylinder body.
An external stop screw shortens the extend stroke to accommodate changing package sizes on a conveyor line, providing flexible 70-100 mm routing.
Field-tuning the extend end position lets a packaging cell adjust mechanical stops for different pallet heights quickly and reliably.
Replace the discontinued SIJ80X100-30SL directly with the SAIJ80X100-30SL, retaining the G3/8 port, M20x1.5 rod thread, and 36 mm cushions. To size both ways: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 30 mm adjust window if your extend stroke needs field tuning between 70 and 100 mm. Mounting options include FA, LB, and TC brackets. The -S magnet enables CS1-B/DS1-B sensors. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
Yes, the SIJ80X100-30SL is discontinued. The exact drop-in replacement is the SAIJ80X100-30SL, which matches the ISO 15552 interface, 80 mm bore, 100 mm stroke, 30 mm adjust window, and G3/8 port.
The 80 mm bore provides 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 (max 513 kgf at 1.0 MPa). The 30 mm adjust window allows shortening the 100 mm extend stroke down to 70 mm on-site.
