This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-75, 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 SUJ32X300-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-75 is a double-acting profile-type standard cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X300-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-75
The AirTAC SUJ32X300-75 is a double-acting, double-rod profile cylinder with a 300 mm nominal stroke and a 75 mm external stop-screw window, letting you trim the extend stroke on-site down to 225 mm. This compact extruded-aluminum body is shorter than a standard cylinder of the same bore and uses a 1/8" port with an M10x1.25 rod thread. This SKU has no magnet and cannot accept a magnetic switch.
The SUJ series is discontinued; the direct replacement is the SAUJ32X300-75, matching the 32 mm bore, force, and FA/LB mounting. The SAUJ upgrade switches to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B, but the stop screw only sets end position and is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X300-75 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 SAUJ32X300-75 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 SUJ32X300-75 Is Used
Variable Length Stops
Trimming the extend stroke by up to 75 mm on-site allows precise positioning of parts without machining custom spacers.
Adjustable Ejector Pins
Dialing in the extend stroke from 225 to 300 mm accommodates changing material thicknesses on an ejection line.
Tuning Transfer Pushers
Field-tuning the push stroke lets operators adjust the end position for different product sizes on a transfer conveyor.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-75 with the SAUJ32X300-75
To replace the discontinued SUJ32X300-75, order the direct replacement SAUJ32X300-75, which preserves the 32 mm bore, 300 mm nominal stroke, 1/8" port, and FA/LB mounting. Choose the 75 mm adjust window if you need to trim the extend stroke by up to 75 mm on-site. Because this non-magnet SKU cannot take a switch, the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For the 300 mm stroke, use external guides to prevent rod bending and side-load wear. The stop screw sets end position but is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-75
- ✓ 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 SUJ32X300-75 FAQ
Yes, the SUJ32X300-75 is discontinued. The direct replacement is the SAUJ32X300-75, offering the same 32 mm bore, 300 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 75 mm adjust window, allowing you to shorten the extend stroke from 300 mm down to 225 mm. The stop sets end position and is not a load lock.
