This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ160X120-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ160X120-75S 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 SIJ160 Double Rod Adjustable Cylinder SIJ160X120-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 120mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ160X120-75S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ160X120-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 160mm bore and 120mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 45-120mm end position. It delivers 10053N push and 9425N pull at 0.5MPa, features a 50mm adjustable air cushion at each end, and uses a G3/4 port. The exact drop-in replacement is the SAIJ160X120-75S, retaining the same interface, force, and mounting.
The SAIJ successor incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, a computed buyer insight from the 0.5MPa data suggests a safe working load around 6032N (60% of push) and a vertical lift capacity of roughly 512kg with a 2:1 margin. Remember 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 SAIJ160X120-75S 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).
Dialing in the exact 45-120mm extend position on-site to seat bearings without overshooting, leveraging the 18095N push force at 0.9MPa.
Adjusting the extend stop by up to 75mm to deflect varying package sizes on a heavy-duty ISO 15552 line without swapping cylinders.
Field-tuning the extend endpoint to act as a physical stop for pallets, using the 50mm adjustable cushion to decelerate heavy 512kg loads.
To replace the discontinued SIJ160X120-75S, order the SAIJ160X120-75S drop-in (insert A after S). The 75mm adjust window is ideal if your exact extend target is unknown during design, letting you dial in 45-120mm on-site. If sizing both ways, the 125mm bore yields 6136N push at 0.5MPa, while the 200mm bore yields 15708N. Mounting options include Basic, FA, LB, and TC. This unit includes the -S magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current switches). For strokes >=300mm, verify side-load guidance to prevent rod binding.
Replacement checklist
Yes, the SIJ160X120-75S is discontinued. The exact drop-in replacement is the SAIJ160X120-75S. It shares the identical ISO 15552 interface, 160mm bore, 120mm nominal stroke, 75mm adjust window, G3/4 port, and mounting options, but adds an upgraded piston seal.
The 160mm bore delivers 10053N push / 9425N pull at 0.5MPa, 14074N push at 0.7MPa, and 18095N push at 0.9MPa. The external stop screw window is 75mm, allowing you to trim the 120mm maximum extend stroke down to 45mm on-site. The stop sets end position and is not a load lock.
