This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X500-10S, 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 SUJ100X500-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X500-10S 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 SAUJ100X500-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X500-10S
The AirTAC SUJ100X500-10S is a double-acting double-rod profile cylinder with a 500 mm nominal stroke and a 10 mm external stop screw window, letting you trim the extend stroke down to 490 mm on-site. It features a 100 mm bore, a 25 mm rod, M20x1.5 rod-end thread, 1/2" port, 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.
Because the SUJ series is discontinued, the direct replacement is the SAUJ100X500-10S, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here, and also offers the SAUF built-in-valve variant. At 500 mm stroke, external guides are recommended to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X500-10S 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 SAUJ100X500-10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 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 SUJ100X500-10S Is Used
Press Fit Tuning
Allows precise 0-10 mm field adjustment of the extend stroke to perfect the seating force of bearings or pins without re-mounting the cylinder.
Transfer Stopper Alignment
Enables operators to dial in the exact 490-500 mm extend position to match varying product widths on a packaging line.
Pallet Positioning
Provides a mechanical stop screw to trim the extend endpoint by up to 10 mm, ensuring precise pallet placement before stretch wrapping.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X500-10S with the SAUJ100X500-10S
To replace the discontinued SUJ100X500-10S, order the direct replacement SAUJ100X500-10S, which preserves the 100 mm bore, 500 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. The 10 mm adjust window is ideal for fine-tuning the extend end position within a 490-500 mm range; if you need more on-site trim, consider a larger adjust window. For the -S magnet option, migrate from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Because the stroke is 500 mm, add external guides to manage side-load and rod-bending risks.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X500-10S
- ✓ 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 SUJ100X500-10S FAQ
Yes, the SUJ100X500-10S is discontinued. The direct replacement is the SAUJ100X500-10S, which matches the 100 mm bore, 500 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 10 mm external stop screw window allows trimming the extend stroke from 500 mm down to 490 mm on-site. The stop sets end position and is not a load lock.
