This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X275-30, 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 SUJ100X275-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X275-30 is a double-acting profile-type standard cylinder with a Ø100mm bore and 275mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X275-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X275-30
The AirTAC SUJ100X275-30 is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, giving a usable 245-275 mm extension out of the 275 mm nominal maximum. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable cushions. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
The direct replacement is the SAUJ100X275-30, matching the bore, stroke, force, port, and SC-series FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors, as this legacy model used CS1-B/DS1-B switches. Because this SKU lacks a magnet, it cannot take a magnetic switch.

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 SAUJ100X275-30 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 SUJ100X275-30 Is Used
Press Fit Tuning
Trimming the extend stroke by up to 30 mm on-site allows precise depth control for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusting the extend position dynamically lets a single diverter accommodate changing package sizes on a packing line.
Pallet Positioning Stop
Field-tuning the stroke end position compensates for pallet height variances, ensuring accurate placement without reprogramming.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X275-30 with the SAUJ100X275-30
To replace the discontinued SUJ100X275-30, order the direct replacement SAUJ100X275-30, which preserves the 100 mm bore, 275 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 30 mm adjust window if you need precise field tuning of the extend stroke; the stop screw sets the end position but does not lock the load, so add an external rod lock for vertical holding. Since this non-magnetic SKU cannot accept switches, migrating to the SAUJ lets you use current CMSG/DMSG/EMSG sensors. For this 275 mm stroke, verify side-load limits, as plain cylinders drift without air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X275-30
- ✓ 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 SUJ100X275-30 FAQ
Yes, the SUJ100X275-30 is discontinued. The direct replacement is the SAUJ100X275-30, which matches the 100 mm bore, 275 mm stroke, 30 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.
The double-acting double-rod cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with an 801 kgf max. The external stop screw shortens the extend stroke by up to 30 mm on-site, yielding a 245-275 mm usable range. The stop sets end position but is not a load lock.
