This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X120-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X120-50 in place of this model. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SUJ Adjustable Cylinder SUJ100X120-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X120-50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 120mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X120-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X120-50
The AirTAC SUJ100X120-50 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 70-120 mm extend out of the 120 mm nominal maximum. This bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. The 1/2" port and M20x1.5 rod end handle high flow, while the 29 mm adjustable cushions absorb kinetic energy.
As this SKU is end-of-life, the exact drop-in replacement is the SAUJ100X120-50, matching the bore, stroke, force, and SC-series mounting. A computed buyer insight: the 3927 N push at 0.5 MPa implies a safe working load of roughly 2356 N, capable of a 200 kg vertical lift with a 2:1 margin. Note this variant lacks a magnet (-S), so it cannot accept a sensor; the SAUJ upgrade transitions to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B. The stop screw sets end position only—it is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X120-50 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X120-50 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 SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SUJ Adjustable Cylinder SUJ100X120-50 Is Used
Variable Stroke Pressing
Trimming the extend stroke by up to 50 mm on-site allows operators to dial in precise pressing depths for different material stacks without swapping the entire cylinder.
Adjustable Diverter Arms
A 70-120 mm extend window lets a single diverter accommodate changing package sizes on a packaging line, tuning the stop position externally via the screw.
Custom End-of-Stroke Stops
When test fixtures require slight positional variations between batches, the external stop screw provides field tuning that avoids machining custom spacers.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X120-50 with the SAUJ100X120-50
To replace the discontinued SUJ100X120-50, order the SAUJ100X120-50; it is a true drop-in retaining the 1/2" port, 120 mm nominal stroke, and 50 mm adjust window. When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Choose the 50 mm adjust window if your fixture needs on-site extend tuning between 70 and 120 mm, which often beats machining a custom fixed-stroke SAU plus an external stop. Mounting uses FA or LB brackets (SC-series compatible). Because this specific SKU has no magnet, you cannot mount a reed switch; upgrading to the SAUJ allows modern CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The stop screw sets the end position but does not lock the load—add an external rod lock or pilot-operated check valve if air loss would cause drifting.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X120-50
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ100X120-50 FAQ
Yes, the SUJ100X120-50 is discontinued. The exact drop-in replacement is the SAUJ100X120-50, which matches the 100 mm bore, 120 mm stroke, 50 mm adjust window, 1/2" port, and force. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The double-acting single-rod 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N at 0.9 MPa (max 801 kgf at 1.0 MPa). The external stop screw trims the extend stroke by up to 50 mm on-site, giving a usable 70-120 mm extend. The stop sets position only and is not a load lock.
