This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-40 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 SIJ80X160-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X160-40, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X160-40 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder. This discontinued unit uses an external stop screw to trim the extend stroke by up to 40 mm on-site, yielding a usable 120-160 mm extension out of the 160 mm nominal maximum. It features a 25 mm rod, M20x1.5 thread, 36 mm adjustable air cushions, a G3/8 port, and operates at 30-800 mm/s. The exact drop-in replacement is the SAIJ80X160-40, matching the bore, stroke, force, and mounting interface.
At 0.5 MPa it delivers 2513 N push and 2268 N pull force, peaking at 4523 N push at 0.9 MPa. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. The SAIJ successor reuses your ISO 15552 mounting and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. This SKU lacks a -S magnet, so it cannot accept position sensors. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

The SAIJ80X160-40 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).
Sheet metal lines needing field stroke tuning to accommodate different bend depths without swapping the entire actuator.
Diverters on packaging conveyors requiring precise extend endpoint adjustments on-site for varying carton lengths.
End-of-line pallet handling where the external stop screw sets different push heights for mixed-load stacking.
To replace the discontinued SIJ80X160-40, order the exact drop-in SAIJ80X160-40, keeping the 160 mm nominal stroke and 40 mm adjust window (120-160 mm usable extend). If resizing, 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. Reuse existing FA, LB, or TC ISO 15552 mounts. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; add external physical switches if detection is required. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. Remember the stop screw merely sets the end position and does not hold loads on air loss—specify a SAIL or BSAI lock variant if load holding is needed.
Replacement checklist
Yes, the SIJ80X160-40 is discontinued. The exact drop-in replacement is the SAIJ80X160-40, which shares the identical ISO 15552 interface, 80 mm bore, 160 mm stroke, 40 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded piston seal for longer life.
This 80 mm bore cylinder has a 40 mm adjust window (usable extend stroke 120-160 mm). Force ratings are: 2513 N push / 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. It uses a G3/8 port and 36 mm adjustable cushions. The stop screw sets end position only and is not a load lock.
