This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-50SH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-50SH 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 SIJ80X100-50SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X100-50SH, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X100-50SH is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder featuring a 50mm external stop screw window. This allows you to trim the extend stroke by up to 50mm on-site, yielding a usable 50-100mm extend out of the 100mm nominal maximum. The drop-in replacement is the SAIJ80X100-50SH, which preserves the exact G3/8 port, M20x1.5 rod thread, 36mm cushions, and 4523N push force at 0.9MPa. This -H variant specifies Viton/FKM seals for 0-150C high-temperature environments.
The SAIJ successor incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life compared to the legacy SIJ. Because the stop screw only sets the end position, it is not a load lock; a plain cylinder drifts on air loss. For sizing, the 2513N push force at 0.5MPa yields a safe working load of roughly 1508N, or a 128kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

The SAIJ80X100-50SH 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 to clamp parts of varying heights without repositioning the entire fixture.
Tunes the extend stroke to deflect different package sizes accurately on a sorting conveyor line.
Sets the exact extend stop position to divert products at specific heights without changing cylinder mounts.
To replace the discontinued SIJ80X100-50SH, order the exact drop-in SAIJ80X100-50SH, matching the 80mm bore, 100mm nominal stroke, 50mm adjust window, G3/8 port, and M20x1.5 rod. If resizing, the neighboring 63mm bore yields 2182N push at 0.7MPa, while the 100mm bore yields 5497N push at 0.7MPa. Choose the 50mm adjust window when your extend stroke needs field tuning between 50 and 100mm. Mounting interfaces include Basic, FA, LB, and TC. The -S suffix ensures piston magnet compatibility for legacy CS1-B/DS1-B switches. For stroke lengths >=300mm, verify side-load limits to prevent rod binding. The stop screw sets end position only; it is not a lock, so use an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
Yes, the SIJ80X100-50SH is discontinued. The exact drop-in replacement is the SAIJ80X100-50SH. It shares the identical ISO 15552 interface, 80mm bore, 100mm nominal stroke, 50mm adjust window, G3/8 port, and 4523N push force at 0.9MPa.
The double-acting single-rod 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a 513kgf max at 1.0MPa. The 50mm external stop screw window allows trimming the extend stroke by up to 50mm on-site, yielding a usable 50-100mm extend. The stop sets end position only and is not a load lock.
