This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X100-40S, 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 SUJ100X100-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-40S 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 SAUJ100X100-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-40S
The AirTAC SUJ100X100-40S is a double-acting, double-rod profile cylinder with an adjustable stroke, meaning an external stop screw allows you to trim the extend stroke by up to 40 mm on-site (usable extend range 60-100 mm). The SUJ series is DISCONTINUED; the direct replacement is the SAUJ100X100-40S, which shares the identical bore, stroke, force, port, and FA/LB mounting.
The SAUJ successor upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit relies on CS1-B/DS1-B switches (indicated by the -S suffix). The external stop screw sets the end position but is not a load lock; you must maintain live air or use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X100-40S 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 SAUJ100X100-40S 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 SUJ100X100-40S Is Used
Variable Depth Pressing
Allows operators to fine-tune the extend stroke by up to 40 mm on-site to accommodate material thickness variations without repositioning the actuator.
Adjustable Diverter Stops
Provides a field-adjustable end position for diverting varying package sizes on a line, letting the stop screw absorb impact and set the exact reach.
Tiered Pallet Positioning
Enables a single cylinder to extend to multiple intermediate heights by limiting the extend stroke on-site, adapting to different pallet stack dimensions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-40S with the SAUJ100X100-40S
To replace the discontinued SUJ100X100-40S, order the SAUJ100X100-40S for an direct match in bore, stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 40 mm adjust window when your application needs field tuning of the extend stroke between 60 and 100 mm. Note the -S sensor change: legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-40S
- ✓ 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 SUJ100X100-40S FAQ
Yes, the SUJ100X100-40S is discontinued. The direct replacement is the SAUJ100X100-40S, which matches the 100 mm bore, 100 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw window is 40 mm, allowing you to trim the extend stroke on-site from the 100 mm maximum down to 60 mm.
