This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X80-30, 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.

The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X80-30 is a double-acting profile-type standard cylinder with a Ø32mm bore and 80mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X80-30, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X80-30 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 50-80 mm extension from the 80 mm nominal maximum. This compact profile body is shorter than an ISO 15552 cylinder of the same bore.
Because this model is end-of-life, the direct replacement is the SAUJ32X80-30, which matches the bore, stroke, 1/8" port, force, and FA/LB mounting. Upgrading to the SAUJ is advantageous because it accepts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here, and the SAU family offers a built-in-valve SAUF variant the SU line lacked. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position rather than locking the load.

The SAUJ32X80-30 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.
Tuning the extend stroke by up to 30 mm on-site allows precise alignment of diverter gates on a conveyor without machining custom spacers.
Adjusting the extend endpoint accommodates different package depths on the fly, ensuring consistent sealing pressure across product changeovers.
Trimming the extend stroke lets an ejection pin retract completely clear of the tool while hitting varied part depths without reprogramming the machine.
To replace the discontinued SUJ32X80-30, specify the direct replacement SAUJ32X80-30, which preserves the 32 mm bore, 80 mm nominal stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 30 mm adjust window if your fixture requires on-site extend tuning between 50 and 80 mm; a fixed SAU plus external stop is bulkier, making the SAUJ preferable for tight profile-body layouts. This non-magnetic SKU cannot accept a switch, but if you need position sensing on the SAUJ, order the -S suffix and migrate to CMSG/DMSG/EMSG sensors since the old CS1-B/DS1-B are obsolete. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear. The stop screw sets the end position and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve.
Replacement checklist
Yes, the SUJ32X80-30 is discontinued. The direct replacement is the SAUJ32X80-30, matching the 32 mm bore, 80 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ accepts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 30 mm adjust window, allowing you to shorten the 80 mm nominal extend stroke down to 50 mm on-site. The stop sets end position and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ32X80-30 replacement — usually within 7-8 hours.
