This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X250-10, 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 SUJ100X250-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X250-10 is a double-acting profile-type standard cylinder with a Ø100mm bore and 250mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X250-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X250-10
The AirTAC SUJ100X250-10 is a double-acting double-rod profile cylinder with a 250 mm nominal stroke and a 10 mm adjustable extend window. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable stroke of 240-250 mm. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ unit is discontinued and the direct replacement is the SAUJ100X250-10, which retains the exact bore, stroke, force, 1/2" port, and SC-series FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X250-10 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 SAUJ100X250-10 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 SUJ100X250-10 Is Used
Press Fit Tuning
Allows operators to dial in the exact 240-250 mm extend endpoint on-site for seating bearings without remachining hard stops.
Divertor Positioning
Provides a micro-adjustable extend stop to fine-tune the actuator reach at a transfer station, compensating for minor mechanical drift.
Pallet Stop Adjustment
Enables precise field tuning of the extend position to accommodate varying pallet dimensions without changing the cylinder body.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X250-10 with the SAUJ100X250-10
To replace the discontinued SUJ100X250-10, order the direct replacement SAUJ100X250-10, matching the 100 mm bore, 250 mm stroke, 10 mm adjust window, and 1/2" port. Choose the 10 mm adjust window when you need fine field-tuning of the extend endpoint rather than a fixed stop. This non-magnetic SKU cannot take a switch; the SAUJ uses CMSG/DMSG/EMSG sensors. Mounting is via FA or LB brackets. For strokes at or above 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X250-10
- ✓ 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 SUJ100X250-10 FAQ
Yes, the SUJ100X250-10 is discontinued. The direct replacement is the SAUJ100X250-10, offering the same 100 mm bore, 250 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 provides a 10 mm adjust window, allowing you to shorten the 250 mm extend stroke down to 240 mm. The stop sets end position and is not a load lock.
