This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X160-30, 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 SUJ50X160-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-30 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 SAUJ50X160-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X160-30
The AirTAC SUJ50X160-30 is a double-acting double-rod profile cylinder with a 50mm bore and 160mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable extend range of 130-160mm. The stop sets the end position but is not a load lock.
This SUJ model is discontinued; the direct replacement is the SAUJ50X160-30, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade shifts to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. As a non-magnet SKU, it cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X160-30 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 SAUJ50X160-30 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 SUJ50X160-30 Is Used
Variable Stroke Clamping
Allows operators to dial in the exact clamping extend position on-site by trimming up to 30mm, accommodating different material thicknesses without changing the cylinder.
Adjustable Transfer Pusher
Enables a transfer pusher to fine-tune its end-stop distance for varied product sizes, using the external screw to set the precise 130-160mm extend window.
Tunable Forming Stop
Provides a compact profile body for packaging lines where the forming stroke needs frequent manual adjustment to set the correct end position for different carton depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-30 with the SAUJ50X160-30
To replace the discontinued SUJ50X160-30, order the direct replacement SAUJ50X160-30. Choose the 30mm adjust window when you need precise field tuning of the extend end-position; the 160mm nominal stroke is the maximum. Mounting is compatible with AirTAC SC-series FA and LB brackets. Because this is a non-magnet SKU, it cannot accept sensors, but the SAUJ upgrade uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For strokes of 300mm or longer, verify side-load limits to prevent rod binding. A plain cylinder does not hold loads on air loss; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-30
- ✓ 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 SUJ50X160-30 FAQ
Yes, the SUJ50X160-30 is discontinued. The direct replacement is the SAUJ50X160-30, which shares the same 50mm bore, 160mm stroke, 30mm adjust window, 1/4" 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 provides a 30mm adjust window, allowing the 160mm extend stroke to be shortened to 130mm on-site. The stop sets end position but is not a load lock.
