This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X450-10, 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 SUJ32X450-10 is a double-acting profile-type standard cylinder with a Ø32mm bore and 450mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X450-10, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X450-10 is a double-acting double-rod profile cylinder with a 450 mm maximum extend stroke that can be trimmed by up to 10 mm on-site via an external stop screw, yielding a usable 440-450 mm window. This compact profile barrel is shorter than a standard ISO 15552 cylinder of the same bore. This SUJ model is discontinued; the direct replacement is the SAUJ32X450-10, sharing the same force, port, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock for held loads. Because the 450 mm stroke is long, use external guides to prevent rod bending. This non-magnet SKU cannot take a sensor. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors, whereas this used legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X450-10 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ32X450-10 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Fine-tunes the extend stroke by up to 10 mm on-site to align a diverter gate precisely without machining hard stops.
Allows operators to dial in the exact 440-450 mm extended stop position for varying package sizes on a packing line.
Provides a safe 241 N working load to push lightweight totes, with field stroke tuning to accommodate guide rail changes.
To replace the discontinued SUJ32X450-10, order the direct replacement SAUJ32X450-10, which matches the 32 mm bore, 450 mm stroke, 10 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 10 mm adjust window if you need fine end-position tuning of the extend stroke within a 440-450 mm range. For stroke lengths of 300 mm or more, such as this 450 mm unit, external guides are recommended to manage side loads and prevent rod bending. Note this non-magnet version cannot accept a sensor; the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
Replacement checklist
Yes, the SUJ32X450-10 is discontinued. The direct replacement is the SAUJ32X450-10, which shares the same 32 mm bore, 450 mm stroke, 10 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 10 mm adjust window, allowing you to shorten the 450 mm extend stroke down to 440 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 SAUJ32X450-10 replacement — usually within 7-8 hours.
