This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X175-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X175-75 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 SIJ80X175-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X175-75, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X175-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and 175 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 100-175 mm extension window. It features a Ø25 mm piston rod, M20x1.5 rod-end thread, G3/8 port, and 36 mm adjustable air cushions. Because this SIJ model is end-of-life, the exact drop-in replacement is the SAIJ80X175-75—delivering the same interface, force, and mounting footprint.
Force output matches the standard single-rod SAI figures: 2513 N push and 2268 N pull at 0.5 MPa, or 3518 N push at 0.7 MPa. A computed buyer insight from the 0.5 MPa data suggests a safe working load around 1508 N (60% of push), translating to a vertical lift capacity of roughly 128 kg with a 2:1 margin. The SAIJ upgrade incorporates an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. Remember the stop screw sets the end position; it is not a load lock, so use an external rod lock or SAIL variant for held loads.

The SAIJ80X175-75 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).
Adjusts the extend stroke on-site by up to 75 mm to accommodate varying material thicknesses without changing the entire actuator setup.
Tunes the pusher end position in real-time to handle different package sizes on a single ISO 15552 mounted line.
Provides a field-trimmable hard stop for pallets of varying heights, relying on the external screw to set the exact extend limit.
To replace the discontinued SIJ80X175-75, order the drop-in SAIJ80X175-75, which preserves the G3/8 port, M20x1.5 thread, and ISO 15552 mounting dimensions for direct reuse of FA, LB, or TC brackets. When sizing both ways, the neighbouring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore provides 5497 N push at 0.7 MPa. Choose the 75 mm adjust window if your assembly requires field tuning between 100 and 175 mm; for tighter needs, select a smaller adjust figure. This non-magnetic SKU lacks a -S sensor groove and cannot accept a reed switch. For strokes at or above 300 mm, verify side-load limits to prevent guide bushing wear. Note that the stop screw only sets end position; it does not hold loads on air loss.
Replacement checklist
Yes, the SIJ80X175-75 is discontinued. The exact drop-in replacement is the SAIJ80X175-75. It shares the identical ISO 15552 interface, 80 mm bore, 175 mm stroke, 75 mm adjust window, G3/8 port, and mounting options, ensuring a seamless swap.
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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extension range of 100-175 mm. The stop sets end position and is not a load lock.
