This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X150-50, 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 SUJ32X150-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X150-50 is a double-acting profile-type standard cylinder with a Ø32mm bore and 150mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X150-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X150-50
The AirTAC SUJ32X150-50 is a discontinued double-acting double-rod profile cylinder with an adjustable extend stroke. An external stop screw lets you trim the extend stroke by up to 50mm on-site, giving a usable stroke of 100-150mm from the 150mm nominal maximum. This compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because this SUJ model is discontinued, the direct replacement is the SAUJ32X150-50, which retains the same 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 this SKU has no magnet and cannot take a sensor; the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X150-50 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 SAUJ32X150-50 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 SUJ32X150-50 Is Used
Variable Pitch Indexing
Tuning the extend stroke by up to 50mm on-site allows a single actuator to drive multiple part lengths without swapping mechanical spacers.
Adjustable Diverter Gate
Field-trim the 150mm extend stroke to set precise gate penetration depths for varying package widths on a sorting line.
Variable Depth Pusher
Shorten the extend stroke on-site to push boxes of different depths into a packing station without reprogramming the motion controller.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X150-50 with the SAUJ32X150-50
To replace the discontinued SUJ32X150-50, specify the SAUJ32X150-50 direct equivalent, matching the 32mm bore, 150mm nominal stroke, 50mm adjust window, and 1/8" port. Choose the 50mm adjust window if your mechanism needs field tuning between 100mm and 150mm extend lengths without machining spacers. Mounting remains interchangeable via FA and LB brackets with the AirTAC SC series. Because this SKU lacks a magnet, you cannot fit a switch; the SAUJ upgrade requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300mm or longer, verify side-load guidance to prevent rod binding. The external stop sets end position but does not lock the load; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X150-50
- ✓ 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 SUJ32X150-50 FAQ
Yes, the SUJ32X150-50 is discontinued. The direct replacement is the SAUJ32X150-50, matching the 32mm bore, 150mm stroke, 50mm adjust window, and 1/8" port. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw shortens the extend stroke by up to 50mm, yielding a usable 100-150mm stroke. The stop sets end position but is not a load lock.
