This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X350-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X350-100 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 SUJ100X350-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X350-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 350mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X350-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-100
The AirTAC SUJ100X350-100 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 250-350 mm extend window from the 350 mm nominal 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 are fixed to the 100 mm bore. This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X350-100, matching the bore, stroke, force, port, and FA/LB mounting.
For sizing, a safe working load is roughly 2356 N (about 60% of the 3927 N push at 0.5 MPa), translating to a vertical lift capacity of about 200 kg with a 2:1 margin. 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. The SAUJ upgrade retains the compact profile barrel and adopts current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches (this no-magnet SKU cannot take a switch).

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 SAUJ100X350-100 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 SUJ100X350-100 Is Used
Variable Pitch Indexing
Adjusting the extend stroke on-site by up to 100 mm allows a single 350 mm cylinder to drive varying material pitches without swapping the entire actuator.
Dynamic Rejecter Arm
Trimming the extend window down to 250 mm lets a sorting arm accommodate changing package sizes on the fly while maintaining the full 7068 N push force at 0.9 MPa.
Variable Height Pallet Stops
The external stop screw sets precise mechanical end positions for different pallet heights, providing a hard physical stop independent of pneumatic pressure.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-100 with the SAUJ100X350-100
To replace the discontinued SUJ100X350-100, order the drop-in SAUJ100X350-100, which preserves the 100 mm bore, 350 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N push at 0.5 MPa. Choose the 100 mm adjust window when you need on-site extend trimming between 250 and 350 mm. Because this SKU lacks a magnet, it cannot accept a sensor; if sensing is required, select an SAUJ with the -S suffix and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. At the 350 mm stroke length, minimize side-load and rod-bending by using external guides to support the payload.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-100
- ✓ 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 SUJ100X350-100 FAQ
Yes, the SUJ100X350-100 is discontinued. The exact drop-in replacement is the SAUJ100X350-100, which matches the 100 mm bore, 350 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B 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 allows you to trim the extend stroke by up to 100 mm on-site, giving a usable window of 250-350 mm. The stop sets end position but is not a load lock; use an external rod lock for held loads.
