This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X75-75, 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.

The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X75-75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 75mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X75-75, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X75-75 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. The nominal 75 mm stroke is the maximum, yielding a usable extend window of 0-75 mm. The stop screw sets the end position; it is not a load lock, so use an external rod lock for held loads.
This SKU has no magnet (-S omitted) and cannot take a magnetic switch. The direct replacement is the SAUJ100X75-75, which retains the exact bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X75-75 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X75-75 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×75 | 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.
Allows operators to dial in the exact 0-75 mm extend position for pressing bearings without machining custom spacers.
Tunes the extend reach on a sorting line to handle changing package widths on the fly via the stop screw.
Sets a precise ejection point for parts of varying lengths, using the full 75 mm trim window to adapt the stroke.
To replace the discontinued SUJ100X75-75, order the SAUJ100X75-75 direct. It keeps the 1/2" port, M20x1.5 rod, 29 mm cushions, and FA/LB mounts. Choose the 75 mm adjust window when you need field-tuning flexibility that beats a fixed SAU plus external stop. This non-magnetic SKU cannot take sensors; if you need position detection, select the SAUJ-S variant and use CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SUJ100X75-75 is discontinued. The direct replacement is the SAUJ100X75-75, which matches the 100 mm bore, 75 mm stroke, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 75 mm, letting you shorten the extend stroke from the 75 mm maximum down to 0 mm on-site. The stop sets end position and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ100X75-75 replacement — usually within 7-8 hours.
