This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X75-50S, 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 SUJ100X75-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X75-50S 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 SAUJ100X75-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X75-50S
The AirTAC SUJ100X75-50S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 25-75 mm extend window from the 75 mm nominal maximum. The stop screw sets the end position and is not a load lock; a plain cylinder drifts on air loss, so fit an external rod lock for held loads.
This SUJ100X75-50S is discontinued; the direct replacement is the SAUJ100X75-50S, matching the bore, stroke, force, port and FA/LB mounting. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B sensors, which must change to current CMSG/DMSG/EMSG switches on the SAUJ.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X75-50S 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 SAUJ100X75-50S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×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.
Where the Airtac SUJ Adjustable Cylinder SUJ100X75-50S Is Used
Variable Press Stroke
Allows operators to dial in the exact 25-75 mm extend reach for a pressing or staking operation without swapping cylinders.
Adjustable Diverter Arm
Tunes the extend length on-site to accommodate different package sizes on a packaging line, ensuring precise routing.
Custom End-Stop Positioning
Provides a field-adjustable hard stop for a pallet lifting or positioning fixture where the exact end point varies by product run.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X75-50S with the SAUJ100X75-50S
To replace the discontinued SUJ100X75-50S, order the direct replacement SAUJ100X75-50S; it retains the 100 mm bore, 75 mm nominal stroke, 50 mm adjust window, 1/2" port and FA/LB mounting. Choose the 50 mm adjust window when you need field-tuning of the extend stroke from 25 to 75 mm. Because this model has the -S magnet, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes at or above 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X75-50S
- ✓ 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 SUJ100X75-50S FAQ
Yes, the SUJ100X75-50S is discontinued. The direct replacement is the SAUJ100X75-50S, offering the same 100 mm bore, 75 mm nominal stroke, 50 mm adjust window, 1/2" port and FA/LB mounting. You must upgrade the -S piston magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
It is a double-acting double-rod cylinder with a 50 mm adjust window, allowing you to shorten the 75 mm nominal extend stroke down to 25 mm. The external stop sets end position but is not a load lock.
