This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X350-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X350-50S 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 SUJ100X350-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X350-50S 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 SAUJ100X350-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-50S
The AirTAC SUJ100X350-50S is a double-acting single-rod adjustable-stroke profile cylinder with a built-in piston magnet. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 300-350 mm extend range from the 350 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" port.
This SUJ unit is discontinued; the exact drop-in replacement is the SAUJ100X350-50S, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. For sizing, the 3927 N push at 0.5 MPa yields a safe working load of roughly 2356 N (60% factor) or a 200 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock, so add an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X350-50S 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 SAUJ100X350-50S 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.

| ×350 | 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 SUJ100X350-50S Is Used
Variable Pitch Indexing
Adjusts the extend stroke by up to 50 mm on-site to tune part ejection distances without swapping cylinders.
Carton Flap Folding
Trims the 350 mm extend stroke dynamically to accommodate varying box heights on a single profile cylinder.
Diverting Gate Actuation
Sets precise end positions for routing different product sizes, using the external stop to dial in the exact reach.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-50S with the SAUJ100X350-50S
To replace the discontinued SUJ100X350-50S, specify the SAUJ100X350-50S drop-in, which preserves the 100 mm bore, 350 mm nominal stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighboring 80 mm bore provides 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N push at 0.5 MPa and 7068 N at 0.9 MPa. Choose the 50 mm adjust window if your fixture needs on-site extend tuning between 300 and 350 mm; the stop screw sets the end position but is not a load lock. For the -S magnet, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. Because the 350 mm stroke exceeds 300 mm, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-50S
- ✓ 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 SUJ100X350-50S FAQ
Yes, the SUJ100X350-50S is discontinued. The exact drop-in replacement is the SAUJ100X350-50S, which matches the 100 mm bore, 350 mm stroke, 50 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 double-acting single-rod cylinder pushes 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa; pull is 3681 N at 0.5 MPa; theoretical max is 801 kgf at 1.0 MPa. The external stop screw window is 50 mm, allowing you to shorten the 350 mm maximum extend stroke down to 300 mm on-site. The stop sets end position only and does not hold the load on air loss.
