This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X165-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X165-75S 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 SUJ100X165-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X165-75S is a double-acting profile-type standard cylinder with a Ø100mm bore and 165mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X165-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X165-75S
The AirTAC SUJ100X165-75S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 90 to 165 mm extension from the 165 mm nominal maximum. This 100 mm bore generates 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. The 1/2 inch port and M20x1.5 rod thread handle high flow, while the 29 mm adjustable cushions manage kinetic energy. This discontinued unit is a direct drop-in for the SAUJ100X165-75S, sharing the exact bore, stroke, force, and FA/LB mounting.
For sizing, the safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa push force), translating to a 200 kg vertical lift with a 2:1 margin. Upgrading to the SAUJ retains the compact profile body but moves sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

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 SAUJ100X165-75S 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 SUJ100X165-75S Is Used
Variable Depth Boring
Machining fixtures requiring field-tuning of the extend stroke to compensate for varying material thicknesses without swapping the entire actuator.
Adjustable Carton Sealing
Packaging lines handling multiple box heights where the 75 mm stop screw window precisely sets the sealing head descent on-site for each format.
Tiered Pallet Positioning
Palletizing cells that need to vary the press descent depth for different product layers, using the 90 to 165 mm usable stroke to adapt quickly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X165-75S with the SAUJ100X165-75S
To replace the discontinued SUJ100X165-75S, specify the SAUJ100X165-75S, which matches the 100 mm bore, 165 mm stroke, 75 mm adjust window, 1/2 inch port, and FA/LB mounting. When sizing, verify your force needs: this bore yields 3927 N push at 0.5 MPa, while the neighboring 80 mm bore provides 2513 N. If you require less force, step down to the 80 mm; if you need more, confirm a larger custom bore. Select the 75 mm adjust window if your process demands field-tuning the extend stroke between 90 and 165 mm, which often beats installing a fixed-stroke cylinder with an external stop. Retain the -S magnet option, but update your sensing to CMSG/DMSG/EMSG switches since the legacy CS1-B/DS1-B sensors are obsolete. For strokes at or exceeding 300 mm, carefully evaluate side-load guidance to prevent rod bearing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X165-75S
- ✓ 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 SUJ100X165-75S FAQ
Yes, the AirTAC SUJ100X165-75S is discontinued. The exact drop-in replacement is the SAUJ100X165-75S. It shares the same 100 mm bore, 165 mm stroke, 75 mm adjust window, 1/2 inch port, and FA/LB mounting. The SAUJ upgrade also moves sensing to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B.
This double-acting single-rod cylinder delivers 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, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 75 mm adjust window, allowing you to trim the extend stroke from the 165 mm nominal maximum down to 90 mm on-site. The stop sets end position only and is not a load lock.
