This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X275-75S, 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 SUJ100X275-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X275-75S 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 SAUJ100X275-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X275-75S
The AirTAC SUJ100X275-75S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 200 to 275 mm extension from the 275 mm nominal maximum. It features a 1/2 inch port, a 25 mm rod, and 29 mm adjustable cushions. This SUJ model is discontinued; the direct replacement is the SAUJ100X275-75S, which preserves the bore, stroke, force, port, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads. Upgrading to the SAUJ changes the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches while retaining the compact profile barrel that is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X275-75S 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 SAUJ100X275-75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 100 | Bore size in mm. |
| ×275 | 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 SUJ100X275-75S Is Used
Variable Stroke Pressing
Allows operators to dial in the exact 200 to 275 mm extend position for pressing bearings or pins without re-engineering the fixture.
Adjustable Diverters
Tunes the extend reach on packaging lines to handle different carton widths on the fly using the 75 mm on-site trim window.
Variable Height Stops
Sets precise mechanical end positions for pallet stops or lifts where the required extension varies by load configuration.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X275-75S with the SAUJ100X275-75S
To replace the discontinued SUJ100X275-75S, order the direct replacement SAUJ100X275-75S, which matches the 100 mm bore, 275 mm nominal stroke, 75 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 75 mm adjust window if your mechanism needs field tuning between 200 and 275 mm; a fixed SAU cylinder plus external stop lacks this integrated profile. If your stroke is 300 mm or longer, verify side-load limits to protect the 25 mm rod. Because this is an -S model, note that the SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches. Mounting compatibility is with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X275-75S
- ✓ 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
