This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X100-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X100-75S 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 SUJ100X100-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-75S is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X100-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-75S
The AirTAC SUJ100X100-75S 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 25-100 mm stroke from the 100 mm nominal maximum. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 rod thread, and a 1/2 inch port. This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X100-75S, sharing the same bore, stroke, force, and SC-series FA/LB mounting.
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. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. Upgrading to the SAUJ retains the compact profile body but moves from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches, and the SAU line adds an SAUF built-in-valve variant the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X100-75S 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 SAUJ100X100-75S 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.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X100-75S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ100X100-75S Is Used
Variable Depth Boring
Adjusts the extend stroke on-site to control boring depth precisely without swapping the entire cylinder setup.
Variable Pitch Sorting
Trims the extend stroke by up to 75 mm to push parts onto different conveyor lanes based on runtime pitch requirements.
Adjustable Height Palletizing
Tunes the extend end position to accommodate varying pallet heights dynamically on the packaging line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-75S with the SAUJ100X100-75S
To replace the discontinued SUJ100X100-75S, specify the SAUJ100X100-75S drop-in: it matches the 100 mm bore, 100 mm nominal stroke, 75 mm adjust window, 1/2 inch port, and FA/LB mounting. 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; select the 100 mm if you need the 200 kg vertical lift capacity. Choose the 75 mm adjust window when you need to tune the extend stroke down to 25 mm on-site, which often beats installing a fixed SAU plus an external stop. Because this unit has the -S magnet, swap the legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAUJ. For stroke lengths of 300 mm or more, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-75S
- ✓ 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 SUJ100X100-75S FAQ
Yes, the SUJ100X100-75S is discontinued. The exact drop-in replacement is the SAUJ100X100-75S, which matches the 100 mm bore, 100 mm stroke, 75 mm adjust window, 1/2 inch port, and FA/LB mounting. You will need to upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 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 push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw window is 75 mm, allowing you to shorten the 100 mm nominal extend stroke down to 25 mm on-site. The stop sets end position only and is not a load lock.
