This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X200-50, 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 SUJ40X200-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X200-50 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 SAUJ40X200-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X200-50
The AirTAC SUJ40X200-50 is a discontinued double-acting double-rod profile cylinder with an adjustable stroke. An external stop screw allows you to trim the extend stroke by up to 50 mm on-site, giving a usable extend range of 150-200 mm from the 200 mm nominal maximum. The stop sets the end position but is not a load lock.
The direct replacement is the SAUJ40X200-50, which matches the bore, stroke, force, port, and SC-series FA/LB mounting. Because this SKU lacks a magnet (-S), it cannot take a switch; furthermore, a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X200-50 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 SAUJ40X200-50 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 SUJ40X200-50 Is Used
Variable Depth Forming
Adjusting the extend stroke on-site by up to 50 mm allows operators to tune press depth for different material thicknesses without changing the cylinder.
Adjustable Transfer Stops
Trimming the extend stroke from 200 mm down to 150 mm lets a single diverter accommodate varying package sizes on a packing line.
Tunable Pusher Pins
The external stop screw provides precise end-position tuning for pusher pins that must adapt to different pallet configurations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-50 with the SAUJ40X200-50
To replace the discontinued SUJ40X200-50, order the direct replacement SAUJ40X200-50, ensuring you migrate from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches if you add an -S option. Choose the 50 mm adjust window if you need on-site extend trimming between 150-200 mm; a fixed SAU plus external stop is bulkier than this integrated profile body. For the 200 mm stroke, verify side-load alignment. Remember the stop screw sets end position only—it is not a lock.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-50
- ✓ 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 SUJ40X200-50 FAQ
Yes, the SUJ40X200-50 is discontinued. The direct replacement is the SAUJ40X200-50, which matches the 40 mm bore, 200 mm stroke, 1/4" 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 50 mm, allowing you to shorten the 200 mm nominal extend stroke down to 150 mm on-site. The stop sets end position and is not a load lock.
