This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X40-30S, 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 SUJ32X40-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X40-30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 40mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X40-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X40-30S
The AirTAC SUJ32X40-30S 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 10-40 mm stroke from the 40 mm nominal maximum. The stop sets the end position but is not a load lock.
This unit is discontinued; the direct replacement is the SAUJ32X40-30S, sharing the same compact profile body, 32 mm bore, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X40-30S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X40-30S 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 SUJ32X40-30S Is Used
Short-Stroke Clamping
Ideal for clamping varied part thicknesses where the 30 mm adjust window allows operators to tune the extend stroke perfectly on-site without swapping cylinders.
Compact Ejection
Fits tight machinery profiles to eject parts, using the external stop to precisely set the ejection distance between 10 and 40 mm for delicate components.
Positional Forming
Provides adjustable end-of-stroke positioning for light forming or pressing tasks, allowing 0.5 MPa force to be applied at exact, field-adjusted depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X40-30S with the SAUJ32X40-30S
To replace the SUJ32X40-30S, order the direct replacement SAUJ32X40-30S, which matches the 32 mm bore, 40 mm nominal stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 30 mm adjust window if your fixture needs field-tuning the extend stroke down to 10 mm; this stop screw sets end position and is not a lock. For position sensing, migrate from the -S legacy CS1-B/DS1-B switches to the SAUJ's CMSG/DMSG/EMSG sensors. Because the nominal stroke is under 300 mm, side-load wear is minimal, but always guide the rod externally.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X40-30S
- ✓ 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 SUJ32X40-30S FAQ
Yes, the SUJ32X40-30S is discontinued. The direct replacement is the SAUJ32X40-30S, which shares the same 32 mm bore, 40 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. You simply migrate the position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 30 mm adjustment window, allowing the 40 mm extend stroke to be shortened down to 10 mm on-site. The stop sets end position and is not a load lock.
