This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X160-50, 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 SUJ50X160-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-50 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 SAUJ50X160-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X160-50
The AirTAC SUJ50X160-50 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 110-160 mm extend out of the 160 mm nominal maximum. The 1/4" port and M16x1.5 rod end match the standard SAU series, but the extruded aluminum profile barrel is notably shorter than an ISO 15552 cylinder of the same bore.
This SUJ model is DISCONTINUED. The direct replacement is the SAUJ50X160-50, retaining the same bore, stroke, force, adjust window, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors (this unit used legacy CS1-B/DS1-B) and opens access to the SAUF built-in-valve variant the SU line lacked. Because this SKU has no magnet, it cannot take a magnetic switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X160-50 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAUJ50X160-50 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×160 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ50X160-50 Is Used
Probe Positioning
Testing fixtures requiring exact extend endpoints can dial in the contact travel precisely without swapping cylinders.
Variable Depth Forming
Light press operations that occasionally change material thicknesses benefit from the 50 mm on-site stroke trim.
Adjustable Diverters
Sorting gates that must reposition for different package sizes can set the extend stop mechanically on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-50 with the SAUJ50X160-50
To replace the discontinued SUJ50X160-50, specify the SAUJ50X160-50 direct. Choose the 50 mm adjust window when you need on-site extend tuning between 110 and 160 mm; the stop screw sets end position but is not a load lock. Mounting uses basic, FA, or LB brackets compatible with AirTAC SC series hardware. Since this SKU lacks a magnet, it cannot accept sensors; if you need position detection, select an SAUJ with the -S suffix and use CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. A plain cylinder drifts on air loss, so add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-50
- ✓ 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 SUJ50X160-50 FAQ
Yes, the SUJ50X160-50 is discontinued. The direct replacement is the SAUJ50X160-50, which matches the 50 mm bore, 160 mm stroke, 50 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 110-160 mm range. The stop sets end position but is not a load lock.
