This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X20-20S, 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 SUJ32X20-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X20-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X20-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X20-20S
The AirTAC SUJ32X20-20S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site. The nominal 20 mm stroke is the maximum, yielding a usable extend range of 0-20 mm. This stop sets the end position; it is not a load lock, so use an external rod lock for held loads.
This SUJ model is discontinued and the direct replacement is the SAUJ32X20-20S, retaining the same compact profile body, bore, stroke, force, and FA/LB mounting. The SAUJ upgrade shifts from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X20-20S 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 SAUJ32X20-20S 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 SUJ32X20-20S Is Used
Gauge Positioning
Trimming the extend stroke by up to 20 mm on-site allows operators to dial in the exact contact point for a pneumatic gauge without machining custom spacers.
Short-Stroke Clamping
Ideal for clamping delicate components where the 0-20 mm usable stroke must be finely adjusted at the machine to prevent over-travel and part damage.
Sensor Actuation
Provides a compact profile body for triggering limit valves where the physical reach needs field tuning to accommodate varying product heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X20-20S with the SAUJ32X20-20S
To replace the discontinued SUJ32X20-20S, specify the SAUJ32X20-20S direct, which matches the 32 mm bore, 20 mm nominal stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. Because the -S suffix indicates a piston magnet, swap the legacy CS1-B/DS1-B sensors for current CMSG/DMSG/EMSG switches on the SAUJ. The 20 mm adjust window is ideal when you need precise field tuning of the extend end position rather than a fixed stop. For this 20 mm stroke, side-load concerns are minimal, but always mount rigidly using SC-series compatible FA or LB brackets.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X20-20S
- ✓ 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 SUJ32X20-20S FAQ
Yes, the SUJ32X20-20S is discontinued. The direct replacement is the SAUJ32X20-20S, which shares the same 32 mm bore, 20 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
The external stop screw provides a 20 mm adjust window, meaning you can shorten the 20 mm nominal extend stroke by up to 20 mm on-site for a 0-20 mm usable range. The stop sets end position and is not a load lock.
