This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X500-20, 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 SUJ100X500-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X500-20 is a double-acting profile-type standard cylinder with a Ø100mm bore and 500mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X500-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X500-20
The AirTAC SUJ100X500-20 is a double-acting, double-rod profile cylinder with an adjustable stroke, discontinued and replaced direct by the SAUJ100X500-20. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 480-500 mm stroke (the 500 mm nominal is the maximum).
The SAUJ successor keeps the exact bore, force, and FA/LB mounting but upgrades sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. Note this non-magnet SKU cannot accept sensors, and the stop screw sets end position without locking the load.

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 SAUJ100X500-20 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 SUJ100X500-20 Is Used
Press Fit Tuning
Allows precise 480-500 mm extend adjustment for pressing parts where exact end-position varies per batch.
Transfer Diverter
Adjusts the extend stop on-site to accommodate different package widths without changing cylinder mounts.
Pallet Stopper
Trims the extend stroke by up to 20 mm to fine-tune pallet end-stops in dynamic layout cells.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X500-20 with the SAUJ100X500-20
To replace the discontinued SUJ100X500-20, order the direct replacement SAUJ100X500-20, which preserves the 100 mm bore, 500 mm stroke, 1/2" port, and FA/LB mounting. The 20 mm adjust window is ideal if your extend target needs on-site tuning between 480-500 mm. Because this is a non-magnet SKU, it cannot take sensors; upgrading to the SAUJ with a -S suffix enables CMSG/DMSG/EMSG sensor accuracy. For the 500 mm stroke, support side-load and rod-bending with external guides. The stop screw sets end position but is not a lock—use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X500-20
- ✓ 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 SUJ100X500-20 FAQ
Yes, the SUJ100X500-20 is discontinued. The direct replacement is the SAUJ100X500-20, matching the 100 mm bore, 500 mm stroke, 1/2" port, and FA/LB mounting. The SAUJ also upgrades sensors to CMSG/DMSG/EMSG.
The external stop screw trims the extend stroke by up to 20 mm on-site (usable 480-500 mm). The stop sets end position and is not a load lock.
