This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X200-100S, 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 SUJ40X200-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X200-100S is a double-acting profile-type standard cylinder with a Ø40mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X200-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X200-100S
The AirTAC SUJ40X200-100S is a double-acting double-rod profile cylinder with a 40mm bore and 200mm maximum stroke, discontinued and replaced direct by the SAUJ40X200-100S. An external stop screw lets you trim the extend stroke by up to 100mm on-site, giving a usable 100-200mm end position.
The stop screw sets the extend end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade keeps the SC-series FA/LB mounting and force but switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X200-100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X200-100S 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 SUJ40X200-100S Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 100mm on-site allows a single cylinder to drive multiple drilling depths on a 40mm bore fixture without changing the entire actuator.
Adjustable Diverter Arms
Routing products of varying sizes on a line is simplified by tuning the pusher end position between 100mm and 200mm to accommodate different package widths.
Variable Height Stops
Adjustable physical stops for pallets or trays allow operators to field-tune the extend position for different pallet heights without reprogramming pneumatic logic.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-100S with the SAUJ40X200-100S
To replace this discontinued SUJ40X200-100S, order the exact direct replacement SAUJ40X200-100S, which preserves the 40mm bore, 200mm nominal stroke, 100mm adjust window, 1/4" port, and FA/LB mounting. Choose the 100mm adjust window if your fixture needs on-site extend tuning from 100 to 200mm; a fixed SAU plus external stop is bulkier. Because this unit has the -S magnet, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For this 200mm stroke, verify side-load limits on the rod end.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-100S
- ✓ 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 SUJ40X200-100S FAQ
Yes, the AirTAC SUJ40X200-100S is discontinued. The direct replacement is the SAUJ40X200-100S, which matches the 40mm bore, 200mm stroke, 100mm adjust window, 1/4" port, and FA/LB mounting. You must upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw window is 100mm, allowing the 200mm maximum extend stroke to be shortened on-site to a 100mm minimum. The stop sets end position and is not a load lock.
