This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X35-30, 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 SUJ50X35-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X35-30 is a double-acting profile-type standard cylinder with a Ø50mm bore and 35mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X35-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X35-30
The AirTAC SUJ50X35-30 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. The nominal 35 mm stroke is the maximum, yielding a usable extend range of 5-35 mm.
The direct replacement is the SAUJ50X35-30, matching the 50 mm bore, 35 mm stroke, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this SUJ used legacy CS1-B/DS1-B switches. As a non-magnet SKU, it cannot take a switch. The stop screw sets end position only; it is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X35-30 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 SAUJ50X35-30 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 SUJ50X35-30 Is Used
Variable Stroke Clamping
Adjusts the extend stroke on-site to clamp parts of varying widths without swapping cylinders.
Positional Stop Tuning
Dials in the exact extend end position for a push-off operation where the 5-35 mm range is critical.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X35-30 with the SAUJ50X35-30
To replace this discontinued SUJ50X35-30, order the SAUJ50X35-30 direct, which preserves the 50 mm bore, 35 mm stroke, 30 mm adjust window, 1/4" port, and SC-series FA/LB mounting. Choose the 30 mm adjust window when you need on-site extend tuning between 5 and 35 mm. Because this is a non-magnet SKU, you cannot mount switches; if sensing is required, select an SAUJ with the -S option for CMSG/DMSG/EMSG compatibility. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. The stop screw sets end position but does not hold loads on air loss; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X35-30
- ✓ 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 SUJ50X35-30 FAQ
Yes, the SUJ50X35-30 is discontinued. The direct replacement is the SAUJ50X35-30, which matches the 50 mm bore, 35 mm stroke, 30 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.
The nominal 35 mm stroke is the maximum; the external stop screw trims the extend stroke by up to 30 mm on-site, yielding a 5-35 mm usable range. The stop sets end position and is not a load lock.
