This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X450-40S, 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 SUJ100X450-40S
The AirTAC SUJ Adjustable Cylinder SUJ100X450-40S is a double-acting profile-type standard cylinder with a Ø100mm bore and 450mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X450-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X450-40S
The AirTAC SUJ100X450-40S is a double-acting double-rod adjustable-stroke profile cylinder, now discontinued. It uses an external stop screw to trim the extend stroke by up to 40 mm on-site, giving a usable extend range of 410-450 mm (the 450 mm nominal is the maximum). The stop screw sets the end position but is not a load lock. It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable cushions.
The direct replacement is the SAUJ100X450-40S, sharing the same profile body, bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads. At 450 mm stroke, use external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X450-40S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X450-40S 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 SUJ100X450-40S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×450 | 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 SUJ100X450-40S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 40 mm on-site allows precise press-fit depth adjustment without machining custom spacers.
Variable Length Diverter
Adjusting the extend end position lets a diverter arm accommodate different package lengths on a single conveyor line.
Adjustable End Stop
Setting the extend stroke between 410 and 450 mm creates a field-tunable end stop for varying pallet widths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X450-40S with the SAUJ100X450-40S
To replace the discontinued SUJ100X450-40S, order the direct replacement SAUJ100X450-40S, which retains the exact 100 mm bore, 450 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 40 mm adjust window if you need to trim the extend stroke on-site. For the -S magnet, the SAUJ uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Because the 450 mm stroke exceeds 300 mm, ensure external guides are used to manage side-load and rod-bending forces. Mounting compatibility is with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X450-40S
- ✓ 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 SUJ100X450-40S FAQ
Yes, the SUJ100X450-40S is discontinued. The direct replacement is the SAUJ100X450-40S, which matches the 100 mm bore, 450 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The theoretical max is 801 kgf at 1.0 MPa. The external stop screw provides a 40 mm adjust window, allowing the extend stroke to be shortened from 450 mm down to 410 mm on-site.
