This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-20, 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 SUJ100X350-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X350-20 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 direct replacement is the SAUJ100X350-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-20
The AirTAC SUJ100X350-20 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, giving a usable extend range of 330-350 mm (the 350 mm nominal stroke is the maximum). The direct replacement is the SAUJ100X350-20, which matches the 100 mm bore, 350 mm stroke, 1/2" port, M20x1.5 rod thread, and FA/LB mounting.
This non-magnetic SKU cannot accept a sensing switch, but the SAUJ upgrade supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. At 350 mm, add external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X350-20 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 SAUJ100X350-20 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 SUJ100X350-20 Is Used
Press Fit Tuning
Trimming the extend stroke by up to 20 mm on-site allows precise depth control for pressing bearings without machining hard stops.
Divertor Positioning
Adjusting the extend end position on the fly accommodates varying package sizes on a sorting line without swapping cylinders.
Pallet Stop Adjustment
Field-tuning the extend stroke lets operators set exact pallet stop locations for different pallet footprints.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-20 with the SAUJ100X350-20
To replace the discontinued SUJ100X350-20, use the SAUJ100X350-20 direct: same 100 mm bore, 350 mm stroke, 1/2" port, and FA/LB mounting. The -20 adjust window allows trimming the extend stroke by up to 20 mm on-site (330-350 mm range), which beats installing a fixed SAU plus an external stop. Because this SKU lacks a magnet, it cannot take sensors; upgrading to the SAUJ allows current CMSG/DMSG/EMSG sensors (replacing CS1-B/DS1-B). For the 350 mm stroke, use external guides to manage side-load and rod bending. The stop screw sets end position only; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-20
- ✓ 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 SUJ100X350-20 FAQ
Yes, the SUJ100X350-20 is discontinued. The direct replacement is the SAUJ100X350-20, matching the 100 mm bore, 350 mm stroke, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 20 mm, allowing the extend stroke to be shortened from 350 mm to 330 mm on-site. The stop sets end position and is not a load lock.
