This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X100-75, 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 SUJ100X100-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X100-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-75
The AirTAC SUJ100X100-75 is a double-acting double-rod adjustable-stroke profile cylinder, now discontinued. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable forward stroke of 25 to 100 mm from the 100 mm nominal maximum. This unit features a 1/2" port, a 25 mm rod, and 29 mm adjustable cushions. The direct replacement is the SAUJ100X100-75, matching the bore, stroke, force, and SC-series FA/LB mounting.
This SKU lacks a magnet (-S omitted) and cannot accept a magnetic switch. The SAUJ upgrade transitions to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads, as air cushions only decelerate.

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 SAUJ100X100-75 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 SUJ100X100-75 Is Used
Variable Depth Forming Press
Dial in the exact material upset distance on-site by trimming the extend stroke up to 75 mm, avoiding the need to machine custom fixed-length spacers for each new batch.
Adjustable Transfer Diverter
Tune the pusher extension length precisely to accommodate different carton widths on a packaging line without swapping out the entire actuator assembly.
Multi-Position Pallet Stop
Set custom end positions for varying pallet depths by adjusting the external stop screw, providing flexible physical limits without complex multi-position valve plumbing.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-75 with the SAUJ100X100-75
To replace the discontinued SUJ100X100-75, order the direct replacement SAUJ100X100-75, which preserves the 100 mm bore, 100 mm nominal stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 75 mm adjust window if your fixture requires a usable extend stroke between 25 and 100 mm. Because this non-magnetic SKU cannot take a switch, upgrading to the SAUJ allows using current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-75
- ✓ 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
