This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X150-20, 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 SUJ32X150-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X150-20 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 SAUJ32X150-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X150-20
The AirTAC SUJ32X150-20 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 130-150 mm extend window from the 150 mm nominal maximum. This SUJ model is discontinued; the direct replacement is the SAUJ32X150-20, matching the bore, stroke, force, and SC-series FA/LB mounting.
The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here, and the SAU family adds an SAUF built-in-valve variant. This non-magnet SKU cannot take a switch. The stop screw sets end position only; it is not a lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X150-20 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 SAUJ32X150-20 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 SUJ32X150-20 Is Used
Diverter Gate Positioning
Trimming the extend stroke by up to 20 mm on-site allows a diverter gate to be perfectly dialed in to match product chute geometry without machining hard stops.
Variable Carton Sealing
Adjusting the extend end position lets a sealing head accommodate slight fluctuations in carton height on the fly, ensuring consistent contact pressure.
Transfer Pusher Tuning
Shortening the extend stroke by up to 20 mm provides exact positioning for a transfer pusher to align parts precisely onto a downstream conveyor lane.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X150-20 with the SAUJ32X150-20
To replace the discontinued SUJ32X150-20, order the direct replacement SAUJ32X150-20, which preserves the 32 mm bore, 150 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if you need precise field tuning of the extend end-position; the stop screw merely sets this position and does not lock the load. Because this specific SKU lacks a magnet, it cannot accept sensors; if sensing is required, select an SAUJ-S model and pair it with current CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, carefully verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X150-20
- ✓ 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 SUJ32X150-20 FAQ
Yes, the SUJ32X150-20 is discontinued. The direct replacement is the SAUJ32X150-20, which matches the 32 mm bore, 150 mm stroke, 20 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 switches.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the 150 mm nominal extend stroke down to 130 mm on-site. The stop sets end position and is not a load lock.
