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

About the Airtac SUJ Adjustable Cylinder SUJ100X500-10
The AirTAC SUJ100X500-10 is a discontinued double-acting double-rod profile cylinder with an adjustable stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 490-500 mm stroke from the 500 mm nominal maximum. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
As SUJ is end-of-life, the direct replacement is the SAUJ100X500-10, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. Note this SKU lacks a magnet for position sensing. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

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 SAUJ100X500-10 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SUJ100X500-10 Is Used
Press Fit Tuning
Dial in the exact bottoming position of a 500 mm extend press fit by trimming up to 10 mm on-site, ensuring parts seat without over-travel.
Divertor End-Stop
Set a precise divertor arm resting position on a packaging line, using the stop screw to micro-adjust the extend endpoint for varying product widths.
Pallet Stop Gate
Adjust the stopping face of a pallet gate actuator by up to 10 mm to accommodate slight pallet size variances without repositioning the cylinder.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X500-10 with the SAUJ100X500-10
To replace the discontinued SUJ100X500-10, use the SAUJ100X500-10 direct: insert an A after the leading S, keeping 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 when you need precise end-position tuning without machining a custom fixed-stroke cylinder. Because this SKU lacks a magnet, it cannot take a switch; if sensing is needed, specify an SAUJ-S and migrate to CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. At 500 mm stroke, mind the side-load and rod-bending limits—use external guides to prevent binding. The adjust stop sets the end position but is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X500-10
- ✓ 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 SUJ100X500-10 FAQ
Yes, the SUJ100X500-10 is discontinued. The direct replacement is the SAUJ100X500-10, offering the same 100 mm bore, 500 mm stroke, 10 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.
This double-acting double-rod cylinder has a 10 mm adjust window, allowing you to trim the extend stroke from 500 mm down to 490 mm. The 1/2" port bore features 29 mm adjustable air cushions.
