This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X150-50SN, 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 SUJ32X150-50SN
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X150-50SN 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 SAUJ32X150-50SN, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X150-50SN
The AirTAC SUJ32X150-50SN 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, yielding a usable 100-150 mm extend range from the 150 mm nominal maximum. The stop sets the end position but is not a load lock. This DISCONTINUED unit is directly replaced by the SAUJ32X150-50SN, matching the 32 mm bore, 1/8" port, and 21 mm cushions.
The SAUJ upgrade retains the compact SC-series mounting but switches from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X150-50SN 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 SAUJ32X150-50SN 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 SUJ32X150-50SN Is Used
Diverter Gate Positioning
Allows operators to field-tune the extend stop within the 100-150 mm window to hit diverter gates precisely without swapping entire actuators.
Variable Carton Sealing
Provides adjustable end-positioning for sealing heads handling mixed carton heights, trimming the extend stroke by up to 50 mm on the fly.
Adjustable Product Stops
Sets a physical end stop for varying product lengths on a conveyor line, using the external screw to dial in the exact 100-150 mm extend distance.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X150-50SN with the SAUJ32X150-50SN
To replace the discontinued SUJ32X150-50SN, order the direct replacement SAUJ32X150-50SN. Select the adjust window based on your exact on-site stroke trim needs (here, up to 50 mm). The SAUJ keeps the FA/LB mounts and the 1/8" port. Because this unit has the -S magnet, you must migrate from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 150 mm stroke, verify side-load limits. A plain cylinder drifts on air loss; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X150-50SN
- ✓ 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 SUJ32X150-50SN FAQ
Yes, the SUJ32X150-50SN is discontinued. The direct replacement is the SAUJ32X150-50SN, which matches the 32 mm bore, 150 mm stroke, 1/8" port, and mounting. You will need to upgrade your sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG.
The external stop screw provides a 50 mm adjust window, meaning the usable extend stroke is 100-150 mm. The stop sets end position only; it is not a load lock.
