This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X160-40S, 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 SUJ50X160-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-40S 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 SAUJ50X160-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X160-40S
The AirTAC SUJ50X160-40S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, giving a usable extend range of 120-160 mm from the 160 mm nominal maximum. It features a 1/4" port, an M16x1.5 rod thread, and 21 mm adjustable air cushions at each end. This discontinued model is directly replaced by the SAUJ50X160-40S, which matches the bore, stroke, force, port, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; plain cylinders drift on air loss, so use an external rod lock for held loads. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. The SAUJ upgrade retains the compact profile barrel—shorter than an ISO 15552 cylinder of the same bore—and switches to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X160-40S 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 SAUJ50X160-40S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ50X160-40S
| 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 SUJ50X160-40S Is Used
Variable Pitch Push Stations
Adjusting the extend stroke by up to 40 mm on-site allows operators to tune push distance for different product lengths without swapping cylinders.
Diverter Gate Positioning
Trimming the extend stroke on the fly sets the exact gate open width for sorting varying package sizes on a single line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-40S with the SAUJ50X160-40S
To replace the discontinued SUJ50X160-40S, order the direct replacement SAUJ50X160-40S, which preserves the 50 mm bore, 160 mm nominal stroke, 40 mm adjust window, 1/4" port, and FA/LB mounting. The 40 mm adjust window is ideal if your end-stop varies by up to 40 mm, avoiding the need for a fixed SAU plus an external stop. For the -S magnet option, note that the SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-40S
- ✓ 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 SUJ50X160-40S FAQ
Yes, the SUJ50X160-40S is discontinued. The direct replacement is the SAUJ50X160-40S, which matches the 50 mm bore, 160 mm stroke, 40 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 found on the SUJ.
The external stop screw provides a 40 mm adjust window, allowing you to shorten the 160 mm nominal extend stroke down to 120 mm on-site. The stop sets end position only and is not a load lock.
