This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X225-100S, 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 SUJ32X225-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X225-100S is a double-acting profile-type standard cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X225-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X225-100S
The AirTAC SUJ32X225-100S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site. This yields a usable extend range of 125-225 mm from the 225 mm nominal maximum. It features a 1/8" port, a Ø12 mm rod, and 21 mm adjustable cushions at each end. This SUJ model is discontinued and is fully replaced by the direct replacement SAUJ32X225-100S, which retains the exact bore, stroke, force, port, and FA/LB mounting.
The SAUJ upgrade transitions from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches while keeping the compact profile barrel shorter than standard cylinders. Remember that the external stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X225-100S 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 SAUJ32X225-100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ32X225-100S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×225 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ32X225-100S Is Used
Variable Length Gauging
Trimming the extend stroke by up to 100 mm on-site allows precise adjustment of measuring arms in quality control fixtures without machining new stops.
Adjustable Forming Stops
Dial in the 125-225 mm extend position for light press operations, accommodating multiple product lengths on the same 32 mm bore cylinder.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X225-100S with the SAUJ32X225-100S
To replace the discontinued SUJ32X225-100S, order the exact direct replacement SAUJ32X225-100S, which preserves the 32 mm bore, 225 mm stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. The 100 mm adjust window is ideal for dialling in the exact 125-225 mm extend position on-site, often beating a fixed SAU plus external stop. If your model has the -S magnet, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, carefully verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X225-100S
- ✓ 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 SUJ32X225-100S FAQ
Yes, the SUJ32X225-100S is discontinued. The direct replacement is the SAUJ32X225-100S, which matches the 32 mm bore, 225 mm stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the 225 mm nominal extend stroke down to 125 mm on-site. The stop sets end position but is not a load lock.
