This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X75-75, 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 SUJ32X75-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-75 is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X75-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-75
The AirTAC SUJ32X75-75 is a double-acting double-rod profile cylinder with a 32mm bore and 75mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, providing exact end-position tuning without mechanical shims. The extruded aluminum profile barrel is more compact than standard cylinders of the same bore. This SKU lacks a magnet and cannot accept a magnetic switch. Operating pressure is 0.15-1.0 MPa, and the 1/8" port drives speeds of 30-800 mm/s.
This SUJ model is discontinued; the direct replacement is the SAUJ32X75-75, matching the bore, stroke, 1/8" port, and FA/LB mounting. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads. The SAUJ upgrade switches sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-75 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 SAUJ32X75-75 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 SUJ32X75-75 Is Used
Custom Clamping Stops
Adjust the extend stroke on-site to clamp parts of varying widths without swapping out the entire cylinder or adding external mechanical spacers.
Variable Transfer Pushers
Tune the pusher end-position precisely for diverting different package sizes on a conveyor line, ensuring positive contact without overtravel.
Prototype Actuation
Dial in the exact extend distance during fixture development, allowing rapid iteration of the motion sequence before finalizing the design.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-75 with the SAUJ32X75-75
To replace the discontinued SUJ32X75-75, order the direct replacement SAUJ32X75-75, which retains the 32mm bore, 75mm stroke, 1/8" port, and FA/LB mounting. The 75mm adjust window allows trimming the extend stroke down to zero on-site, which is ideal when a fixed SAU plus external stop would waste space. Because this is a non-magnet SKU, it cannot accept sensors; the SAUJ upgrade uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For strokes of 300mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-75
- ✓ 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 SUJ32X75-75 FAQ
Yes, the AirTAC SUJ32X75-75 is discontinued. The direct replacement is the SAUJ32X75-75, which matches the 32mm bore, 75mm stroke, 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 75mm adjust window, allowing you to trim the 75mm extend stroke down to zero on-site. The stop sets end position only and is not a load lock.
