This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X160-100, 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 SUJ50X160-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-100 is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X160-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X160-100
The AirTAC SUJ50X160-100 is a double-acting double-rod profile cylinder with a 160 mm nominal extend stroke that you can shorten on-site by up to 100 mm via an external stop screw, yielding a usable 60-160 mm stroke window. The stop screw sets the end position; it is not a load lock, so fit an external rod lock for held loads.
The direct replacement is the SAUJ50X160-100, which preserves the exact bore, stroke, 1/4" port, force, and SC-series FA/LB mounting. Upgrading to the SAUJ is driven by sensor compatibility: this legacy SUJ used CS1-B/DS1-B switches, whereas the SAUJ accepts current CMSG/DMSG/EMSG sensors. Because this specific SKU lacks a magnet, it cannot take a magnetic switch.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X160-100 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 SUJ50X160-100 Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site to push parts of varying widths into a press without re machining hard stops.
Adjustable Diverter Arms
Setting precise reach distances on a packaging line to deflect different carton sizes accurately.
Custom Format Stops
Dialing in the extend position on demand for sorting pallets of varying depths in a compact profile layout.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-100 with the SAUJ50X160-100
To replace the discontinued SUJ50X160-100, order the direct replacement SAUJ50X160-100, matching the 50 mm bore, 160 mm nominal stroke, 100 mm adjust window, and 1/4" port. Choose the 100 mm adjust window when you need to tune the extend stroke down to a 60 mm minimum on-site; the external stop sets end position but is not a lock, so add an external rod lock for held loads. Retain your FA or LB mounts from the SC series. If adding sensing, note the SAUJ uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B, though this non-magnet SKU cannot accept a switch. For this 160 mm stroke, side-load is minimal, but for any stroke over 300 mm, verify your guide shafts to prevent binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-100
- ✓ 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 SUJ50X160-100 FAQ
Yes, the SUJ50X160-100 is discontinued. The direct replacement is the SAUJ50X160-100, which matches the 50 mm bore, 160 mm stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw shortens the 160 mm extend stroke by up to 100 mm on-site, yielding a 60-160 mm usable window. The stop sets end position and is not a load lock.
