This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-30S 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 SIJ80X160-30S 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 SAIJ80X160-30S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X160-30S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 130-160 mm window from the 160 mm nominal maximum. The 80 mm bore yields 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. It features a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions. The exact drop-in replacement is the SAIJ80X160-30S, sharing the same interface, force, and mounting.
For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), equating to a 128 kg vertical lift with a 2:1 margin. The stop sets end position but is not a load lock; use SAIL or BSAI for held loads. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X160-30S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ80X160-30S 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).
Adjusting the extend stroke on-site by up to 30 mm allows a single 80 mm bore cylinder to press parts of varying heights without changing the entire actuator setup.
Trimming the extend stroke from 160 mm down to 130 mm accommodates different package sizes on a sorting line, providing flexible physical stopping points.
Fine-tuning the end position by 30 mm on-site lets a lift mechanism settle pallets into distinct rack tiers without requiring multiple fixed-stroke cylinders.
To replace the discontinued SIJ80X160-30S, order the drop-in SAIJ80X160-30S, reusing your FA, LB, or TC ISO 15552 mounts. To size both ways: the 63 mm bore gives 1559 N push at 0.5 MPa, while the 100 mm bore gives 3927 N. Choose the 30 mm adjust window when you need on-site extend trimming between 130-160 mm. The -S magnet supports legacy CS1-B/DS1-B sensors (current AirTAC switches on the SAIJ). For strokes >=300 mm, verify side-load guide tolerance. Remember the stop screw sets end position and does not lock; for load holding without live air, specify an external rod lock or SAIL variant.
Replacement checklist
Yes, the SIJ80X160-30S is discontinued. The exact drop-in replacement is the SAIJ80X160-30S. It shares the same ISO 15552 interface, 80 mm bore, 160 mm stroke, 30 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 at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The external stop screw window is 30 mm, allowing the extend stroke to be shortened from the 160 mm maximum down to 130 mm on-site. The stop sets end position and is not a load lock.
