This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-50S 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 SIJ80X160-50S 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 SAIJ80X160-50S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X160-50S 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 50 mm on-site, giving a usable 110-160 mm window from the 160 mm nominal maximum. The exact drop-in replacement is the SAIJ80X160-50S, matching the G3/8 port, M20x1.5 rod thread, and 36 mm cushions. This 80 mm bore outputs 2513 N push and 2268 N pull at 0.5 MPa.
The SAIJ successor retains the ISO 15552 mounting interface while upgrading to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; the cylinder drifts on air loss. For safe sizing, expect a working load around 1508 N (60% of the 0.5 MPa push) or a 128 kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X160-50S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ80X160-50S 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).
Tuning the extend stroke on-site by up to 50 mm allows a single 160 mm cylinder to drive multiple product pitches without changing the entire actuator assembly.
Trimming the extend stroke to 110-160 mm accommodates varying package sizes on a transfer line, ensuring precise placement without repositioning hard stops.
Field-adjusting the extend end position handles different pallet depths or layer heights, providing flexible 2513 N push force for diverse load profiles.
To replace the discontinued SIJ80X160-50S, order the exact drop-in SAIJ80X160-50S to reuse the existing ISO 15552 mounting (Basic, FA, LB, TC). If sizing both ways, the adjacent 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 50 mm adjust window when you need on-site extend tuning between 110-160 mm. Select the -S option for position sensing. Note: for strokes >=300 mm, guide the side-load to prevent rod binding. The stop screw defines end position only; for load holding on air loss, use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
Yes, the SIJ80X160-50S is discontinued. The exact drop-in replacement is the SAIJ80X160-50S. It shares the same ISO 15552 interface, 80 mm bore, 160 mm stroke, 50 mm adjust window, G3/8 port, and mounting dimensions, but features 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 provides a 50 mm adjust window, shortening the extend stroke from 160 mm down to 110 mm. The stop sets end position and is not a load lock.
