This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X200-75, 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 SUJ100X200-75
The AirTAC SUJ Adjustable Cylinder SUJ100X200-75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 200mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X200-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X200-75
The AirTAC SUJ100X200-75 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke on-site by up to 75 mm, yielding a usable 125 to 200 mm stroke. The nominal 200 mm remains the maximum. Because this SKU lacks a magnet, it cannot accept a magnetic switch.
The direct replacement is the SAUJ100X200-75, matching the bore, stroke, 1/2" port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X200-75 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 SAUJ100X200-75 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 SUJ100X200-75 Is Used
Press Fit Tuning
Allows operators to dial in the exact 125 to 200 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke by up to 75 mm to deflect varying package sizes on a conveyor line without swapping the cylinder.
Adjustable Height Stop
Provides a field-tunable end stop for pallets or lifts where the final extend position must be tweaked during commissioning.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X200-75 with the SAUJ100X200-75
To replace the discontinued SUJ100X200-75, order the SAUJ100X200-75 direct: same 100 mm bore, 200 mm max stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. Choose the -75 mm adjust window if your mechanism needs on-site extend tuning between 125 and 200 mm; for fixed endpoints, a standard SAU cylinder is simpler. Because this SKU has no magnet, you cannot mount sensors; the SAUJ with a -S suffix adds a magnet for CMSG/DMSG/EMSG switches. For strokes at or over 300 mm, verify side-load guidance to prevent rod binding. The stop screw sets end position and does not hold loads on air loss—add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X200-75
- ✓ 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
Airtac SUJ Adjustable Cylinder SUJ100X200-75 FAQ
