This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X150-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X150-20S 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 SUJ100X150-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X150-20S is a double-acting profile-type standard cylinder with a Ø100mm bore and 150mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X150-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X150-20S
The AirTAC SUJ100X150-20S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 130-150 mm extend window from the 150 mm nominal maximum. This discontinued unit delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa. The 1/2" port and M20x1.5 rod end handle high flow, while the 29 mm adjustable air cushions absorb heavy end-of-stroke kinetic energy. The stop sets end position but is not a load lock; a plain cylinder drifts on air loss, so fit an external rod lock for held loads.
Because this model is discontinued, the exact drop-in replacement is the SAUJ100X150-20S, retaining the same bore, stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ upgrades the -S magnet sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push figure), translating to a vertical lift capacity of about 200 kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X150-20S 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 SAUJ100X150-20S 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 SUJ100X150-20S Is Used
Press Fit Tuning
Dial in the exact insertion depth of bearings or pins by trimming the extend stroke up to 20 mm on-site, preventing over-travel on delicate press fits.
Variable Height Sealing
Adjust the extend end position to accommodate different carton heights or film cutoff points without reprogramming the machine cycle.
End-Stop Calibration
Fine-tune the final resting position of heavy forming tools to compensate for mechanical wear or material thickness variation directly at the fixture.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X150-20S with the SAUJ100X150-20S
To replace the discontinued SUJ100X150-20S, specify the SAUJ100X150-20S as a direct drop-in, keeping the 100 mm bore, 150 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounts. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N push at 0.5 MPa and 7068 N at 0.9 MPa. Choose the 20 mm adjust window when you need precise end-position tuning without shimming. The -S suffix means a built-in magnet; swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAUJ. For strokes at or above 300 mm, verify side-load limits to prevent guide bushing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X150-20S
- ✓ 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 SUJ100X150-20S FAQ
Yes, the SUJ100X150-20S is discontinued. The exact drop-in replacement is the SAUJ100X150-20S, which shares the same 100 mm bore, 150 mm nominal stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. You only need to upgrade the -S magnet switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
The 100 mm bore single-rod cylinder provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. The external stop screw offers a 20 mm adjust window, shortening the 150 mm nominal extend stroke down to 130 mm on-site. This stop sets the end position but does not lock the load; use an external rod lock for load holding.
