This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X150-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X150-75S 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 SUJ100X150-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X150-75S 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 SAUJ100X150-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X150-75S
The AirTAC SUJ100X150-75S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75mm on-site, yielding a usable 75-150mm range from the 150mm nominal maximum. It delivers 3927N push and 3681N pull at 0.5MPa, peaking at 7068N push at 0.9MPa. The 100mm bore carries a 25mm rod, M20x1.5 rod-end thread, 29mm adjustable air cushions, and a 1/2" port. This model is discontinued; the exact drop-in replacement is the SAUJ100X150-75S, sharing the same bore, stroke, force, port, and FA/LB mounting.
For sizing, the computed safe working load is roughly 2356N (about 60% of the 3927N push at 0.5MPa), translating to a 200kg vertical lift with a 2:1 margin. Two distinct advantages stand out: first, the SAUJ upgrade shifts legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches while retaining the compact profile barrel; second, tuning the extend stop on-site often beats fitting a fixed-stroke SAU plus a bulky external mechanical stop. Remember the stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X150-75S 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 SAUJ100X150-75S 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 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 SUJ100X150-75S Is Used
Variable Depth Boring
Machining fixtures requiring field stroke tuning to set precise boring depths between 75mm and 150mm without swapping the entire cylinder.
Adjustable Carton Sealing
Packaging lines handling varied box heights where the extend stroke must be trimmed on-site to lower a sealing head precisely onto different cartons.
Variable Height Palletizing
Automated palletizing cells needing to adjust the extend end position on the fly to accommodate varying pallet load heights safely.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X150-75S with the SAUJ100X150-75S
To replace this discontinued SUJ100X150-75S, specify the SAUJ100X150-75S drop-in, retaining the 150mm nominal stroke, 75mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighbouring 80mm bore yields 2513N push at 0.5MPa, while the 100mm bore provides 3927N push and 3681N pull at 0.5MPa. Select the 75mm adjust window if your extend stroke needs on-site tuning between 75mm and 150mm. Because this model has the -S magnet, you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes at or above 300mm, verify side-load limits to prevent guide wear. The stop screw sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X150-75S
- ✓ 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 SUJ100X150-75S FAQ
Yes, the SUJ100X150-75S is discontinued. The exact drop-in replacement is the SAUJ100X150-75S, which shares the same 100mm bore, 150mm stroke, 75mm adjust window, 1/2" port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The 100mm bore double-acting single-rod cylinder delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and 7068N push at 0.9MPa, with a theoretical max of 801kgf. The external stop screw provides a 75mm adjust window, allowing you to trim the extend stroke on-site from the 150mm maximum down to 75mm. The stop sets end position only and is not a load lock.
