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

About the Airtac SUJ Adjustable Cylinder SUJ50X160-50S
The AirTAC SUJ50X160-50S is a discontinued 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 window from the 160 mm nominal maximum. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This stop screw strictly sets the end position and is not a load lock.
As the SUJ series is end-of-life, the direct replacement is the SAUJ50X160-50S, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. A plain cylinder drifts on air loss, so add an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X160-50S 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 SAUJ50X160-50S 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 SUJ50X160-50S
| 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 SUJ50X160-50S Is Used
Variable Pitch Indexing
Allows operators to dial in exact extend distances from 110 to 160 mm on the fly for parts with differing heights or pitch requirements without swapping cylinders.
Adjustable Reject Diverter
Provides field-tuned extension to push varying product sizes off a belt, letting maintenance shorten the stroke by up to 50 mm to accommodate new package dimensions.
Dynamic Stop Positioning
Acts as a hard stop for incoming pallets where the exact contact point varies, using the external screw to set the final resting position precisely on-site.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-50S with the SAUJ50X160-50S
To replace the discontinued SUJ50X160-50S, order the direct replacement SAUJ50X160-50S, which preserves the 50 mm bore, 160 mm nominal stroke, 50 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 50 mm adjust window when you need on-site extend tuning from 110 to 160 mm; the external stop sets end position but is not a load lock, so specify an external rod lock for vertical holding. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For this 160 mm stroke, side-load is minimal, but for any stroke >=300 mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-50S
- ✓ 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 SUJ50X160-50S FAQ
Yes, the SUJ50X160-50S is discontinued. The direct replacement is the SAUJ50X160-50S, which matches the 50 mm bore, 160 mm stroke, 50 mm adjust window, 1/4" port, and FA/LB mounting. You must upgrade the position sensing from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 50 mm adjust window, allowing you to shorten the extend stroke from the 160 mm maximum down to 110 mm on-site. This stop sets the end position and is not a load lock.
