This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X100-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X100-100S 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 SIJ80X100-100S 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 SAIJ80X100-100S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X100-100S 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 100 mm on-site, giving a usable 0-100 mm extend window from the 100 mm nominal maximum. This 80 mm bore uses a G3/8 port, a Ø25 mm rod, and 36 mm adjustable air cushions. The stop screw sets the end position; it is not a load lock, and loads drift without live air.
The exact drop-in replacement is the SAIJ80X100-100S, reusing the same ISO 15552 mounting interface, force, and porting. Force output is 2513 N push and 2268 N pull at 0.5 MPa, rising to 3518 N at 0.7 MPa. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. Computed buyer insight: safe working load is ~1508 N (60% of the 0.5 MPa push), yielding a ~128 kg vertical lift with a 2:1 margin.

The SAIJ80X100-100S 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 allows a single cylinder to drive a drill head to multiple precise depths without changing the entire actuator assembly.
Sorting lines can tune the pusher extension distance on the fly to accommodate varying package sizes moving down the belt.
End-of-line pallet stops can be field-adjusted to present different loading heights for manual wrapping or banding operations.
To replace this discontinued model, order the SAIJ80X100-100S; it is a drop-in swap retaining the G3/8 port, M20x1.5 rod thread, and ISO 15552 mounting dimensions (Basic, FA, LB, TC). When sizing both ways, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 100 mm adjust window when you need maximum field flexibility to trim the extend stroke. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches (SAIJ uses current switches). For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding. Because the stop screw is not a lock, specify an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
Yes, the SIJ80X100-100S is discontinued. The exact drop-in replacement is the SAIJ80X100-100S, which matches the 80 mm bore, 100 mm stroke, 100 mm adjust window, G3/8 port, and ISO 15552 mounting interface.
The double-acting single-rod force is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N at 0.9 MPa, with a 513 kgf theoretical max at 1.0 MPa. The external stop screw window is 100 mm, letting you shorten the extend stroke by up to 100 mm on-site. The stop sets end position and is not a load lock.
