This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X275-20S, 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 SUJ32X275-20S
The AirTAC SUJ Adjustable Cylinder SUJ32X275-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 275mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X275-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X275-20S
The AirTAC SUJ32X275-20S is a double-acting double-rod profile cylinder with a 32mm bore and 1/8" port. An external stop screw lets you trim the extend stroke by up to 20mm on-site, giving a usable 255-275mm range. This discontinued model is fully replaced by the SAUJ32X275-20S.
The direct replacement SAUJ32X275-20S shares the same compact profile body, force, and FA/LB mounting, but upgrades sensing to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B. 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 SAUJ32X275-20S 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 SAUJ32X275-20S 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 SUJ32X275-20S Is Used
Adjustable End Stops
Trimming the extend stroke by up to 20mm on-site allows operators to fine-tune part ejection distances without swapping cylinders.
Feed Position Tuning
Dialing in the 255-275mm extend range accommodates varying package sizes on a packaging line directly at the machine.
Prototype Actuation
Setting precise end positions for test fixtures is simplified using the external stop screw during short-stroke prototyping.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X275-20S with the SAUJ32X275-20S
To replace the discontinued SUJ32X275-20S, order the exact direct replacement SAUJ32X275-20S, which preserves the 32mm bore, 275mm stroke, 1/8" port, and FA/LB mounts. The 20mm adjust window is ideal for field tuning the extend stroke without machining; for fixed lengths, a standard SAU cylinder suffices. The -S magnet on this legacy model used CS1-B/DS1-B switches, which must be upgraded to CMSG/DMSG/EMSG sensors on the SAUJ. For this 275mm stroke, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X275-20S
- ✓ 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 SUJ32X275-20S FAQ
Yes, the SUJ32X275-20S is discontinued. The direct replacement is the SAUJ32X275-20S, which matches the 32mm bore, 275mm stroke, 20mm adjust window, and FA/LB mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
This 32mm bore cylinder features a 20mm adjust window (usable extend stroke 255-275mm). It operates at 30-800mm/s with a 1/8" port.
