This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X130-30S, 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 SUJ50X130-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X130-30S is a double-acting profile-type standard cylinder with a Ø50mm bore and 130mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X130-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X130-30S
The AirTAC SUJ50X130-30S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 100-130 mm extend window from the 130 mm nominal maximum. This discontinued unit features a built-in piston magnet for position sensing, a Ø20 mm rod, adjustable 21 mm cushions, and a 1/4" port. The stop screw sets the end position but is not a load lock; loads drift on air loss.
The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X130-30S 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 SAUJ50X130-30S 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 SUJ50X130-30S Is Used
Variable Pitch Indexing
Allows operators to dial in the exact extend reach between 100 mm and 130 mm on-site to accommodate different material thicknesses without swapping the entire actuator.
Adjustable Diverter Gate
Fine-tunes the pusher stroke by up to 30 mm in the field to handle varying package sizes on a packaging line, ensuring precise routing without reprogramming the motion controller.
Custom Length Stopper
Provides a mechanical end-stop for pallets or workpieces that can be shortened on-site from the 130 mm maximum, offering flexibility when downstream machine spacing changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X130-30S with the SAUJ50X130-30S
To replace the SUJ50X130-30S, specify the SAUJ50X130-30S; it is a direct retaining the 50 mm bore, 130 mm max stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. Select the 30 mm adjust window if you need field tuning between 100 mm and 130 mm; for fixed 130 mm extend, a standard SAU cylinder suffices. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. A plain cylinder does not hold loads without live air; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X130-30S
- ✓ 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 SUJ50X130-30S FAQ
Yes, the AirTAC SUJ50X130-30S is discontinued. The direct replacement is the SAUJ50X130-30S, which matches the 50 mm bore, 130 mm stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. You must upgrade your position sensing from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors.
The external stop screw offers a 30 mm adjust window, meaning the usable extend stroke can be field-trimmed from the 130 mm nominal maximum down to 100 mm. The stop sets end position and is not a load lock.
