This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X200-50, 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 SUJ32X200-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X200-50 is a double-acting profile-type standard cylinder with a Ø32mm bore and 200mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X200-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X200-50
The AirTAC SUJ32X200-50 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, giving a usable extend range of 150 to 200 mm from the 200 mm nominal maximum. This compact extruded-aluminum body is shorter than a standard cylinder of the same bore.
This SUJ model is discontinued; the direct replacement is the SAUJ32X200-50, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. Note that this non-magnet SKU cannot accept a sensor, and the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X200-50 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X200-50 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 SUJ32X200-50 Is Used
Variable Pitch Feed
Adjusting the extend stroke on-site by up to 50 mm allows a packaging machine to handle varying product lengths without swapping cylinders.
Transfer Gate Positioning
Trimming the 200 mm extend stroke lets operators fine-tune a diverter gate's resting position to match changing conveyor lane widths.
Adjustable Mechanical Stop
Using the external stop screw to set a precise 150 mm extend endpoint provides a hard mechanical limit for stacking or lifting tasks.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X200-50 with the SAUJ32X200-50
To replace the discontinued SUJ32X200-50, specify the SAUJ32X200-50 direct, which preserves the 32 mm bore, 200 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if your mechanism needs field tuning of the extend stroke by up to 50 mm; otherwise, a fixed SAU cylinder is simpler. Because this is a non-magnet SKU, it cannot accept a sensor—upgrade to the -S suffix on the SAUJ for CMSG/DMSG/EMSG compatibility. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. Finally, the external stop screw only sets the end position; it is not a lock, so add an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X200-50
- ✓ 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 SUJ32X200-50 FAQ
Yes, the SUJ32X200-50 is discontinued. The direct replacement is the SAUJ32X200-50, which matches the 32 mm bore, 200 mm stroke, 50 mm adjust window, 1/8" 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 trim the 200 mm nominal extend stroke down to 150 mm on-site. The stop sets end position and is not a load lock.
