This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X300-100, 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 SUJ100X300-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X300-100 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 SAUJ100X300-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X300-100
The AirTAC SUJ100X300-100 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 200-300 mm extend window from the 300 mm nominal maximum. The stop screw sets the end position but is not a load lock. It features a 1/2 inch port, a 25 mm rod, and 29 mm adjustable cushions.
Because this model is end-of-life, the direct replacement is the SAUJ100X300-100, which preserves the bore, stroke, force, and SC-series FA/LB mounting. Note this non-magnet SKU cannot take a switch; the SAUJ upgrade moves sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X300-100 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 SAUJ100X300-100 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 SUJ100X300-100 Is Used
Variable Press Stroke
Allows operators to dial in the exact extend distance on a press without changing the cylinder, trimming up to 100 mm to accommodate different material thicknesses.
Adjustable Diverter Arm
Fine-tunes the reach of a sorting arm on a conveyor line by shortening the extend stroke on-site to handle varying package sizes.
Custom End-Stop Positioning
Sets a precise physical end position for a pallet stopper where the exact 200-300 mm engagement point must be tuned during machine commissioning.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X300-100 with the SAUJ100X300-100
To replace the discontinued SUJ100X300-100, order the direct replacement SAUJ100X300-100, matching the 100 mm bore, 300 mm nominal stroke, 100 mm adjust window, and 1/2 inch port. Choose the 100 mm adjust window only if you need the full 200-300 mm extend trim range. Retain FA or LB mounting from the SC series. This SKU lacks a magnet and cannot accept a sensor; the SAUJ upgrade requires switching from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For the 300 mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X300-100
- ✓ 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 SUJ100X300-100 FAQ
Yes, the SUJ100X300-100 is discontinued. The direct replacement is the SAUJ100X300-100, which matches the 100 mm bore, 300 mm stroke, 100 mm adjust window, 1/2 inch port, and SC-series FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw trims the extend stroke by up to 100 mm on-site, giving a 200-300 mm usable window. The stop sets end position and is not a load lock; add an external rod lock for held loads.
