This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X30-10S, 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 SUJ40X30-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X30-10S is a double-acting profile-type standard cylinder with a Ø40mm bore and 30mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X30-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X30-10S
The AirTAC SUJ40X30-10S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site. This yields a usable 20-30 mm extend window from the 30 mm nominal maximum, ideal for field stroke tuning. It features a 1/4" port, a 16 mm rod, and adjustable 21 mm cushions.
This SUJ unit is discontinued and replaced by the direct replacement SAUJ40X30-10S, which retains the exact bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. The stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X30-10S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X30-10S 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 SUJ40X30-10S Is Used
Short-Stroke Clamping
Provides adjustable 20-30 mm clamping travel for delicate workpieces, allowing operators to dial in the exact grip without changing the entire cylinder.
Sensor Positioning
Fine-tunes the extend endpoint by up to 10 mm on-site for precise part detection, compensating for mechanical wear or fixture variations.
Ejector Stroke Tuning
Sets a custom ejection distance within a 20-30 mm window to push varying product sizes off a line without re-engineering the pneumatic layout.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X30-10S with the SAUJ40X30-10S
To replace the discontinued SUJ40X30-10S, order the direct replacement SAUJ40X30-10S, matching the 40 mm bore, 30 mm nominal stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window when you need precise 20-30 mm extend tuning. Because this unit has the -S magnet, you must switch from legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches on the SAUJ. As this 30 mm stroke is under 300 mm, side-load risks are minimal. Remember the stop screw is not a lock; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X30-10S
- ✓ 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 SUJ40X30-10S FAQ
Yes, the SUJ40X30-10S is discontinued. The direct replacement is the SAUJ40X30-10S, offering the same 40 mm bore, 30 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw allows trimming the extend stroke by up to 10 mm on-site, giving a usable 20-30 mm extend window. The stop sets end position and is not a load lock.
