This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAUJ32X350-30S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 SUJ32X350-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X350-30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X350-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X350-30S
The AirTAC SUJ32X350-30S is a double-acting single-rod profile cylinder with a 32 mm bore and 350 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 320-350 mm window. The 1/8" port and extruded aluminum barrel make it shorter than standard cylinders of the same bore. This unit is discontinued; the exact drop-in replacement is the SAUJ32X350-30S, retaining the 402 N push force at 0.5 MPa and M10x1.25 rod thread.
At 0.5 MPa it delivers 402 N push and 345 N pull, giving a safe working load of roughly 241 N or a 20 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. Because the 350 mm stroke invites rod bending, add external guides to manage side loads. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches, which the SAUJ upgrades to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X350-30S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X350-30S 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 SUJ32X350-30S Is Used
Adjustable End-Stop Machining
Dialing in the exact extend position for a machining head or deburring tool on-site, using the 30 mm trim window to fine-tune the 350 mm stroke without swapping cylinders.
Variable-Length Sorting Diverter
Accommodating different package sizes on a conveyor line by adjusting the extend stroke within the 320-350 mm range to hit the correct sorting lane position.
Custom Positioning Stops
Setting precise mechanical end stops for pallet positioning fixtures, allowing operators to trim the extend stroke by up to 30 mm as payload dimensions change.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X350-30S with the SAUJ32X350-30S
To replace the discontinued SUJ32X350-30S, order the drop-in SAUJ32X350-30S, which matches the 32 mm bore, 350 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. When sizing, the 40 mm neighbor bore offers higher force (628 N push at 0.5 MPa), while dropping to 0.5 MPa operation on the 32 mm bore yields a 402 N push. Select the 30 mm adjust window if you need on-site extend tuning between 320-350 mm. For the -S magnet version, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG on the SAUJ. Because the 350 mm stroke exceeds 300 mm, ensure external guides are used to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X350-30S
- ✓ 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 SUJ32X350-30S FAQ
Yes, the SUJ32X350-30S is discontinued. The exact drop-in replacement is the SAUJ32X350-30S, which shares the same 32 mm bore, 350 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The double-acting single-rod cylinder delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and 724 N push at 0.9 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The external stop screw provides a 30 mm adjust window, allowing you to shorten the 350 mm extend stroke down to 320 mm on-site. The stop sets end position and is not a load lock.
