This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X300-30S, 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 SUJ100X300-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X300-30S 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 SAUJ100X300-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X300-30S
The AirTAC SUJ100X300-30S is a double-acting double-rod profile cylinder with a 100mm bore and 300mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable 270-300mm window. This unit is discontinued; the direct replacement is the SAUJ100X300-30S, matching the bore, stroke, force, port and FA/LB mounting.
The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. At 300mm stroke, use external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X300-30S 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 SAUJ100X300-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X300-30S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×300 | 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 SUJ100X300-30S Is Used
Press Fit Tuning
Adjusting the extend stop on-site by up to 30mm allows operators to dial in the exact insertion depth for press-fit pins without re-engineering the fixture.
Variable Length Diverter
A 270-300mm extend window lets a single diverter arm accommodate changing package sizes on a packing line by trimming the stroke endpoint in the field.
Adjustable End Stop
Set precise mechanical end positions for pallet stops, using the external screw to compensate for wear or varying pallet depths without repositioning the cylinder.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X300-30S with the SAUJ100X300-30S
To replace the discontinued SUJ100X300-30S, order the direct replacement SAUJ100X300-30S, keeping the 100mm bore, 300mm nominal stroke, 30mm adjust window, 1/2" port and FA/LB mounting. Choose the 30mm adjust window when you need precise field tuning of the extend endpoint. For the -S magnet option, switch from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Because the stroke is 300mm, ensure external guides to manage side-load and rod-bending forces.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X300-30S
- ✓ 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 SUJ100X300-30S FAQ
Yes, the SUJ100X300-30S is discontinued. The direct replacement is the SAUJ100X300-30S. It matches the 100mm bore, 300mm stroke, 30mm adjust window, 1/2" port and FA/LB mounting. The SAUJ also offers the SAUF built-in-valve variant the SU line lacked.
The external stop screw provides a 30mm adjust window, making the usable extend stroke 270-300mm. The stop sets end position but is not a load lock.
