This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X275-75, 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 SUJ32X275-75 is a double-acting profile-type standard cylinder with a Ø32mm bore and 275mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X275-75, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X275-75 is a double-acting, double-rod profile cylinder with an adjustable extend stroke, discontinued and replaced by the SAUJ32X275-75. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 200-275 mm stroke window. The nominal 275 mm stroke represents the maximum extend length.
This compact profile barrel is shorter than an ISO 15552 cylinder of the same bore. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ direct retains FA/LB mounting but upgrades sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X275-75 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ32X275-75 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.
Feeding parts of differing lengths on a line by dialing the extend stroke within the 200-275 mm window without swapping cylinders.
Tuning a sorting gate's reach on-site to handle changing package widths on a conveyor belt.
Ejecting products from a shelf at varying depths by trimming the extend stroke up to 75 mm.
To replace the discontinued SUJ32X275-75, order the direct replacement SAUJ32X275-75, which matches the 32 mm bore, 275 mm max stroke, 1/8" port, and FA/LB mounting. Choose the 75 mm adjust window if your mechanism requires field tuning the extend stroke between 200 and 275 mm. Because this SKU lacks a magnet, it cannot take a switch; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
Yes, the SUJ32X275-75 is discontinued. The direct replacement is the SAUJ32X275-75, which matches the 32 mm bore, 275 mm stroke, 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 75 mm adjust window, allowing the extend stroke to be shortened on-site from the 275 mm maximum down to 200 mm. 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 SAUJ32X275-75 replacement — usually within 7-8 hours.
