This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-40S, 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 SUJ32X300-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-40S 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 SAUJ32X300-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-40S
The AirTAC SUJ32X300-40S is a double-acting double-rod adjustable-stroke profile cylinder, now discontinued and replaced by the direct replacement SAUJ32X300-40S. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable 260-300 mm extend range from the 300 mm nominal maximum. The stop sets the end position but is not a load lock.
The SAUJ replacement retains the exact bore, stroke, force, port, and FA/LB mounting, but upgrades sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. A plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X300-40S 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 SAUJ32X300-40S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ32X300-40S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×300 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ32X300-40S Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to control drill depth for different material thicknesses without changing the cylinder.
Variable Length Diverter
Tunes the pusher stroke by up to 40 mm to deflect varying package sizes on a conveyor line accurately.
Adjustable Stop Positioning
Sets a precise mechanical end-stop for pallets or workpieces when exact spacing is required on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-40S with the SAUJ32X300-40S
To replace the discontinued SUJ32X300-40S, order the direct replacement SAUJ32X300-40S, which matches the 32 mm bore, 300 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. Choose the adjust window based on your maximum needed extend length; here you can shorten the stroke by up to 40 mm on-site. The -S magnet version requires switching from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. For this 300 mm stroke, use external guides to prevent rod bending and manage side loads. Mounting is compatible with AirTAC SC series accessories.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-40S
- ✓ 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 SUJ32X300-40S FAQ
Yes, the SUJ32X300-40S is discontinued. The direct replacement is the SAUJ32X300-40S, which shares the same 32 mm bore, 300 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ upgrades the sensor compatibility from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw allows you to trim the extend stroke by up to 40 mm on-site, yielding a usable extend range of 260-300 mm. The stop sets end position and is not a load lock.
