This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X500-50S, 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 SUJ100X500-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X500-50S 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 SAUJ100X500-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X500-50S
The AirTAC SUJ100X500-50S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 450-500 mm extend window from the 500 mm nominal maximum. It features a 1/2" port, a 25 mm rod, M20x1.5 rod threads, and 29 mm adjustable cushions. This SUJ model is discontinued; the direct replacement is the SAUJ100X500-50S, which retains the bore, stroke, force, port, and FA/LB mounting.
The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Remember the stop screw sets end position only; it is not a load lock, so add an external rod lock for held loads. At 500 mm stroke, use external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X500-50S 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 SAUJ100X500-50S 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 SUJ100X500-50S Is Used
Variable-Length Ejector
Tuning the extend stroke by up to 50 mm on-site allows an ejection mechanism to adapt to mixed part lengths without re-mounting the cylinder.
Adjustable Transfer Stop
Field-trim the 500 mm stroke to act as a precise transfer stop for varying pallet widths on a conveyor line.
Variable-Height Lift Platen
Shorten the extend stroke on-site to set exact lifting heights for different container sizes, using the external stop screw.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X500-50S with the SAUJ100X500-50S
To replace the discontinued SUJ100X500-50S, order the direct replacement SAUJ100X500-50S, ensuring you migrate from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. The 50 mm adjust window is ideal if your extend endpoint needs field tuning between 450-500 mm. Mounting remains compatible with AirTAC SC series FA and LB brackets. Because the 500 mm stroke is long, verify side-load limits and use external guides to prevent rod bending. The stop screw merely sets the end position; it is not a lock, so specify an external rod lock for pneumatic load-holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X500-50S
- ✓ 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 SUJ100X500-50S FAQ
Yes, the SUJ100X500-50S is discontinued. The direct replacement is the SAUJ100X500-50S, which matches the 100 mm bore, 500 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw allows you to trim the extend stroke by up to 50 mm on-site, giving a usable 450-500 mm extend window. The stop sets end position only and is not a load lock.
