This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X500-40S, 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 SUJ100X500-40S
The AirTAC SUJ Adjustable Cylinder SUJ100X500-40S is a double-acting profile-type standard cylinder with a Ø100mm bore and 500mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X500-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X500-40S
The AirTAC SUJ100X500-40S is a double-acting double-rod profile cylinder with a 500 mm nominal stroke and a 40 mm adjustable extend window, letting you trim the forward stroke on-site down to 460 mm via an external stop screw. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ unit is discontinued and superseded by the direct replacement SAUJ100X500-40S, which retains the exact bore, stroke, force, 1/2" port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. At 500 mm stroke, external guides are recommended to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X500-40S 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 SAUJ100X500-40S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×500 | 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 SUJ100X500-40S Is Used
Variable Pitch Indexing
Tuning the extend stroke on-site by up to 40 mm to alter part spacing without machining new hard stops.
Adjustable Transfer Pusher
Trimming the forward stroke from 500 mm down to 460 mm to adapt to varying package sizes on the fly.
Pallet Positioning Stop
Fine-tuning the end-stop position in the field to square pallets accurately before wrapping.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X500-40S with the SAUJ100X500-40S
To replace the discontinued SUJ100X500-40S, order the SAUJ100X500-40S; it is a direct swap matching the 100 mm bore, 500 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 40 mm adjust window if your mechanism needs field-tuning the extend stroke between 460 mm and 500 mm without shimming. Because this unit has the -S magnet, you must migrate from legacy CS1-B/DS1-B sensors to the modern CMSG/DMSG/EMSG switches on the SAUJ. Finally, at 500 mm stroke, verify side-load limits and add external guides to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X500-40S
- ✓ 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 SUJ100X500-40S FAQ
Yes, the SUJ100X500-40S is discontinued. The direct replacement is the SAUJ100X500-40S, matching the 100 mm bore, 500 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. You simply migrate the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 40 mm external stop screw window allows you to shorten the 500 mm extend stroke down to 460 mm on-site. The stop sets end position only; it is not a load lock.
