This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X270-20S, 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 SUJ32X270-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X270-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 270mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X270-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X270-20S
The AirTAC SUJ32X270-20S 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, giving a usable 250-270 mm stroke. This SUJ model is discontinued; order the direct replacement SAUJ32X270-20S instead.
The SAUJ32X270-20S keeps the same 32 mm bore, 270 mm nominal stroke, force, and SC-series FA/LB mounting. Upgrading is required for sensing: this legacy -S model uses CS1-B/DS1-B switches, while the SAUJ uses current CMSG/DMSG/EMSG sensors. The stop screw sets end position only; it is not a load lock, so add an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X270-20S 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 SAUJ32X270-20S 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 SUJ32X270-20S Is Used
Adjustable End Stops
Trimming the extend stroke by up to 20 mm on-site allows operators to fine-tune end positions for parts with slight dimensional variations without re-engineering the fixture.
Sorting Diverter Setup
A 250-270 mm extend window provides the exact reach needed to deflect varying package sizes on a sorting line, ensuring positive contact without bottoming out.
Packaging Pinch Adjustments
Field-tuning the extend stroke lets packaging machinery accommodate different carton depths on the fly, ensuring proper sealing pressure across product changeovers.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X270-20S with the SAUJ32X270-20S
To replace the discontinued SUJ32X270-20S, order the direct replacement SAUJ32X270-20S. It preserves the 32 mm bore, 270 mm stroke, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if you need field tuning of the extend stroke. Because this -S model uses legacy CS1-B/DS1-B switches, you must migrate to CMSG/DMSG/EMSG sensors on the SAUJ. At 270 mm stroke (over 300 mm), verify side-load alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X270-20S
- ✓ 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 SUJ32X270-20S FAQ
Yes, the SUJ32X270-20S is discontinued. The direct replacement is the SAUJ32X270-20S, which matches the 32 mm bore, 270 mm stroke, 1/8" port, and FA/LB mounting. You must upgrade sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 20 mm adjust window, making the usable extend stroke 250-270 mm. The stop sets end position and is not a load lock.
