This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X150-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X150-10S 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.

The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X150-10S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X150-10S 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 10 mm on-site, yielding a usable 140-150 mm stroke. The nominal 150 mm is the maximum. It features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, a G3/8 port, and speeds of 30-800 mm/s. The exact drop-in replacement is the SAIJ80X150-10S, retaining the same interface, force, and mounting.
Force output is 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. A computed buyer insight indicates a safe working load of roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. The SAIJ upgrade utilizes an upgraded two Y-shaped one-way piston seal for low start-up pressure. Note that the external stop sets end position but is not a load lock; for held loads use SAIL/BSAI variants.

The SAIJ80X150-10S 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).
Allows operators to dial in the exact 140-150 mm extend position for seating bearings without remachining hard stops.
Adjusts the extend stroke on-site to accommodate slight product size variations on a packaging line.
Provides a field-tunable end position to align pallets precisely before stretch wrapping.
To replace the discontinued SIJ80X150-10S, map directly to the SAIJ80X150-10S (insert A after S), keeping the 80 mm bore, 150 mm stroke, 10 mm adjust window, G3/8 port, and -S magnet for legacy CS1-B/DS1-B switches. If sizing both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa. The 10 mm adjust window is ideal for fine-tuning the extend end position. Mounting options include Basic, FA, LB, and TC using genuine ISO 15552 interface dimensions. Because the 150 mm stroke is under 300 mm, side-load concerns are minimal. The stop screw is not a lock; without live air the piston drifts.
Replacement checklist
Yes, the SIJ80X150-10S is discontinued. The exact drop-in replacement is the SAIJ80X150-10S. It shares the same ISO 15552 interface, 80 mm bore, 150 mm stroke, 10 mm adjust window, G3/8 port, and mounting. The SAIJ features an upgraded piston seal.
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. The theoretical max is 513 kgf at 1.0 MPa. The external stop screw window is 10 mm, shortening the extend stroke from 150 mm to 140 mm. The stop sets position and is not a load lock.
