This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X30-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X30-30S 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 SUJ100X30-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X30-30S is a double-acting profile-type standard cylinder with a Ø100mm bore and 30mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X30-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X30-30S
The AirTAC SUJ100X30-30S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site (usable extend range 0-30 mm). The nominal 30 mm stroke is the maximum. It 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 Ø25 rod provide high flow and rigidity. This unit is discontinued; the exact drop-in replacement is the SAUJ100X30-30S, sharing the same bore, stroke, force, port, and FA/LB mounting.
For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), equating to a 200 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade keeps the compact profile body but switches sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. The -S suffix confirms the built-in magnet for position sensing.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X30-30S 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 SAUJ100X30-30S 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 SUJ100X30-30S Is Used
Short-Stroke Clamping
Field-tunes the extend stop to dial in exact clamping force on variable-width parts without reprogramming the machine cycle.
Transfer Diverter
Adjusts the extend stroke on-site to accommodate different product sizes on a packaging line, ensuring precise diverting angles.
Pallet Positioning
Trims the extend stroke to set exact push distances for aligning pallets before stretch wrapping, adapting to pallet variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X30-30S with the SAUJ100X30-30S
To replace the discontinued SUJ100X30-30S, order the drop-in SAUJ100X30-30S. If you need to size both ways, the neighbouring 80 mm bore gives 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. Choose the 30 mm adjust window when you need precise field tuning of the extend stroke. Mounting is compatible with AirTAC SC series FA and LB brackets. Because this model has the -S suffix, you must upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For any stroke >=300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X30-30S
- ✓ 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 SUJ100X30-30S FAQ
Yes, the SUJ100X30-30S is discontinued. The exact drop-in replacement is the SAUJ100X30-30S. It shares the same 100 mm bore, 30 mm stroke, 3927 N push force at 0.5 MPa, 1/2" port, and FA/LB mounting. You only need to upgrade the -S position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 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. The external stop screw provides a 30 mm adjust window, allowing you to shorten the extend stroke from the 30 mm maximum down to 0 mm on-site. The stop sets the end position and is not a load lock.
