This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X300-10, 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 SUJ100X300-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X300-10 is a double-acting profile-type standard cylinder with a Ø100mm bore and 300mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X300-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X300-10
The AirTAC SUJ100X300-10 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, giving a usable 290-300 mm stroke. The 1/2" port and extruded aluminum profile barrel make it shorter than standard cylinders of the same bore.
This SUJ model is discontinued; the direct replacement is the SAUJ100X300-10, sharing the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. Note this SKU lacks a magnet and cannot take a sensor; the stop screw sets end position but is not a load lock.

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 SAUJ100X300-10 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 SUJ100X300-10 Is Used
Press Fit Tuning
Trimming the 300 mm extend stroke by up to 10 mm on-site allows exact bottoming position for pressing bearings without machining hard stops.
Divertor Positioning
Adjusting the extend end position in 1 mm increments lets operators fine-tune divertor arm reach on the fly as product sizes change.
Pallet Stop Calibration
The external stop screw provides a field-adjustable mechanical end position for pallet stops, ensuring precise alignment without reprogramming.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X300-10 with the SAUJ100X300-10
To replace the discontinued SUJ100X300-10, use the direct replacement SAUJ100X300-10, which preserves the 100 mm bore, 300 mm max stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 10 mm adjust window if you need precise 290-300 mm extend tuning; a fixed SAU plus external stop is bulkier. Because this SKU has no magnet, you cannot mount sensors; upgrading to the SAUJ requires switching to CMSG/DMSG/EMSG switches. Since the stroke is 300 mm, use external guides to prevent rod bending under side loads. The stop screw sets end position only; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X300-10
- ✓ 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 SUJ100X300-10 FAQ
Yes, the SUJ100X300-10 is discontinued. The direct replacement is the SAUJ100X300-10, which matches the 100 mm bore, 300 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 external stop screw allows you to trim the extend stroke by up to 10 mm on-site, yielding a usable 290-300 mm stroke. The stop sets end position only; it is not a load lock.
