This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X175-100, 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 SUJ100X175-100
The AirTAC SUJ Adjustable Cylinder SUJ100X175-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X175-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-100
The AirTAC SUJ100X175-100 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, giving a usable extend range of 75-175 mm from the 175 mm nominal maximum. It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable air cushions. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
The direct replacement is the SAUJ100X175-100, sharing the same bore, stroke, force, port, and FA/LB mounting. This base SKU has no magnet and cannot take a switch. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B and offers the SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-100 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 SAUJ100X175-100 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 SUJ100X175-100 Is Used
Variable Pitch Forming
Bends or stamps parts to different lengths on the same fixture by dialing the extend stroke down 100 mm on-site, avoiding cylinder swaps between product runs.
Adjustable Transfer Pusher
Tunes the pusher extend distance to match varying package widths on a packaging line, using the stop screw to set precise ejection endpoints.
Custom Sorting Diverter
Adjusts the diverter stroke on-site to route different carton sizes into specific lanes without needing multiple fixed-stroke actuators.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-100 with the SAUJ100X175-100
To replace the discontinued SUJ100X175-100, order the direct replacement SAUJ100X175-100, which matches the 100 mm bore, 175 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 100 mm adjust window only if you genuinely need to trim the extend stroke on-site across a 75-175 mm range. Because this SKU lacks a magnet, it cannot take a switch; if you need position sensing, select an SAUJ with the -S suffix and use CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-100
- ✓ 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 SUJ100X175-100 FAQ
Yes, the SUJ100X175-100 is discontinued. The direct replacement is the SAUJ100X175-100, which matches the 100 mm bore, 175 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 100 mm, allowing you to trim the extend stroke from the 175 mm nominal maximum down to 75 mm on-site. The stop sets end position but is not a load lock.
