This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X350-10, 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 SUJ40X350-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X350-10 is a double-acting profile-type standard cylinder with a Ø40mm bore and 350mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X350-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X350-10
The AirTAC SUJ40X350-10 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 340-350 mm stroke. It is discontinued; the direct replacement is the SAUJ40X350-10, matching the 40 mm bore, 350 mm stroke, 1/4" port, and FA/LB mounting. The stop screw sets the end position but is not a load lock.
The SAUJ upgrade retains the compact profile barrel but switches sensing to current CMSG/DMSG/EMSG switches, as this non-magnetic SUJ SKU cannot take a sensor and used legacy CS1-B/DS1-B brackets.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X350-10 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X350-10 produces the same force from the same bore. 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 SUJ40X350-10 Is Used
Dialing in Clamp Depth
Trimming the 350 mm extend stroke by up to 10 mm on-site to set an exact clamping depth on varying workpiece heights without swapping the cylinder.
Transfer Stop Positioning
Fine-tuning the end position of a diverter gate on a packaging line by adjusting the external stop screw to account for belt wear or product size changes.
Adjustable Pusher Stroke
Setting a precise ejection distance for cartons of different lengths, using the 10 mm adjust window to prevent overtravel on shorter boxes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X350-10 with the SAUJ40X350-10
To replace the discontinued SUJ40X350-10, order the direct replacement SAUJ40X350-10, which preserves the 10 mm adjust window, 1/4" port, M12x1.25 rod thread, and 21 mm cushions. The SAUJ is ideal when you need on-site stroke tuning without adding an external stop to a fixed SAU cylinder. Because this is a non-magnetic SKU, it cannot take a switch; if sensing is needed, use the SAUJ with CMSG/DMSG/EMSG sensors. For the 350 mm stroke, support the rod against side-load bending with external guides. Note that the adjustable stop sets end position only; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X350-10
- ✓ 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 SUJ40X350-10 FAQ
Yes, the SUJ40X350-10 is discontinued. The direct replacement is the SAUJ40X350-10, which shares the same 40 mm bore, 350 mm stroke, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B, though this specific non-magnetic SKU cannot take a switch.
The external stop screw offers a 10 mm adjust window, allowing you to shorten the 350 mm extend stroke down to 340 mm on-site. The stop sets end position only and is not a load lock.
