This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X100-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X100-30 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 SUJ100X100-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-30 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 SAUJ100X100-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-30
The AirTAC SUJ100X100-30 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, yielding a usable 70-100 mm stroke out of the 100 mm nominal maximum. At 0.5 MPa it delivers 3927 N push and 3681 N pull force through a 1/2" port. This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X100-30, matching the bore, stroke, force, port, and FA/LB mounting.
The SAUJ upgrade accepts current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. Because this specific SKU lacks a magnet, it cannot take a magnetic switch. For sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X100-30 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 SAUJ100X100-30 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 SUJ100X100-30 Is Used
Variable Stroke Pressing
Allows operators to dial in the exact 70-100 mm extend position for assembling parts with varying heights without re-engineering the fixture.
Adjustable Diverter Arm
Tunes the pusher extension on-site to handle different package widths on a packaging line, ensuring positive contact without overtravel.
Custom End-Stop Positioning
Provides a mechanical end-stop for pallet lifting or positioning where the exact bottom position must be tweaked after installation.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-30 with the SAUJ100X100-30
To replace the discontinued SUJ100X100-30, specify the SAUJ100X100-30 drop-in: it preserves the 100 mm stroke, 30 mm adjust window, 1/2" 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 hits 5497 N at 0.7 MPa. Choose the 30 mm adjust window if you need field tuning between 70 and 100 mm. The SAUJ uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For strokes at or over 300 mm, verify side-load limits. This non-magnet SKU cannot support sensing.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-30
- ✓ 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 SUJ100X100-30 FAQ
Yes, the SUJ100X100-30 is discontinued. The exact drop-in replacement is the SAUJ100X100-30, which matches the 100 mm bore, 100 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and 801 kgf max at 1.0 MPa. The external stop screw provides a 30 mm adjust window, allowing the extend stroke to be shortened from the 100 mm maximum down to 70 mm. The stop sets position only and does not lock the load.
