This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X275-75S, 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 SUJ32X275-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X275-75S 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 SAUJ32X275-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X275-75S
The AirTAC SUJ32X275-75S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75mm on-site, yielding a usable 200-275mm stroke from the 275mm nominal maximum. This SUJ32X275-75S is discontinued; the direct replacement is the SAUJ32X275-75S, sharing the same compact profile body, force, and SC-series FA/LB mounting.
Note that the stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade transitions from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches while retaining the M10x1.25 rod thread and 21mm cushions.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X275-75S 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 SAUJ32X275-75S 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 SUJ32X275-75S Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning down to 200mm for machines running mixed product lengths without swapping the entire cylinder.
Adjustable Divert Stroke
Fine-tunes the pusher end position by up to 75mm on-site to accommodate varying package widths on a packaging line.
Customizable Stop Position
Sets precise material stop locations in a 32mm bore handling system, adjusting the extend endpoint for different pallet sizes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X275-75S with the SAUJ32X275-75S
To replace the discontinued SUJ32X275-75S, specify the direct replacement SAUJ32X275-75S, which preserves the 32mm bore, 275mm nominal stroke, 75mm adjust window, 1/8" port, and FA/LB mounting. Select the 75mm adjust window if your application requires field tuning the extend stroke down to 200mm; otherwise, a fixed-stroke SAU avoids the external stop. Because this unit has an -S magnet, upgrade your legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches. For this 275mm stroke, verify side-load alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X275-75S
- ✓ 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 SUJ32X275-75S FAQ
Yes, the SUJ32X275-75S is discontinued. The direct replacement is the SAUJ32X275-75S, which matches the 32mm bore, 275mm stroke, 75mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 75mm adjust window, allowing you to shorten the extend stroke from 275mm down to 200mm. The stop sets end position and is not a load lock.
