This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X400-75, 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 SUJ32X400-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X400-75 is a double-acting profile-type standard cylinder with a Ø32mm bore and 400mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X400-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X400-75
The AirTAC SUJ32X400-75 is a double-acting, double-rod adjustable-stroke profile cylinder, now discontinued and superseded by the direct replacement SAUJ32X400-75. It features a 32mm bore, 12mm rod, and a 1/8" port. The external stop screw lets you trim the extend stroke by up to 75mm on-site, giving a usable extend range of 325-400mm (the 400mm nominal stroke is the maximum). This stop screw strictly sets the end position; it is not a load lock, so external rod locks are required for held loads.
The compact profile barrel is shorter than standard cylinders of the same bore. The SAUJ replacement retains the exact bore, stroke, force, and SC-series FA/LB mounting, but upgrades sensing to current CMSG/DMSG/EMSG sensors (this non-magnetic SUJ lacks a piston magnet and cannot take switches).

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X400-75 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 SAUJ32X400-75 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SUJ Adjustable Cylinder SUJ32X400-75 Is Used
Variable Depth Boring
Machine tools needing field stroke tuning to hit precise boring depths between 325mm and 400mm without swapping the entire cylinder body.
Adjustable Transfer Stops
Conveyor diverters where the extend stop screw is fine-tuned on-site to accommodate changing package sizes or varying product lengths on the line.
Custom Pusher Fixtures
Material handling pushers that require a 75mm adjustment window to dial in the exact ejection distance for different pallet configurations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X400-75 with the SAUJ32X400-75
To replace this discontinued model, order the SAUJ32X400-75; it is a direct swap matching the 32mm bore, 400mm stroke, 75mm adjust window, 1/8" port, and FA/LB mounting. Choose the 75mm adjust window if your fixture needs on-site extend tuning between 325-400mm. Because this SKU lacks a piston magnet, it cannot accept sensors; the SAUJ upgrade supports modern CMSG/DMSG/EMSG switches (the SUJ used legacy CS1-B/DS1-B). For the 400mm stroke, use external guides to prevent rod bending and manage side loads. Remember, the adjustable stop sets end position but does not lock the load on air loss—add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X400-75
- ✓ 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 SUJ32X400-75 FAQ
Yes, the SUJ32X400-75 is discontinued. The direct replacement is the SAUJ32X400-75, which matches the 32mm bore, 400mm stroke, 75mm adjust window, 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 adjustment window, allowing you to shorten the extend stroke from the 400mm maximum down to 325mm on-site. This stop sets the end position and is not a load lock.
