This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X75-40TC, 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 SUJ Adjustable Cylinder SUJ32X75-40TC is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X75-40TC, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X75-40TC is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, giving a usable extend range of 35-75 mm from the 75 mm nominal maximum. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 32 mm bore version features a 12 mm rod, M10x1.25 rod thread, and a 1/8" port.
This SUJ model is discontinued and the direct replacement is the SAUJ32X75-40TC, which matches the bore, stroke, force, port, and TC mounting interface. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches; note this specific SKU lacks a magnet and cannot take a sensor at all. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-40TC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ32X75-40TC 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.
Bending or pressing stations that need to alter the extend reach by up to 40 mm between product runs without swapping the entire actuator.
Diverting or stopping different package sizes on a line by tuning the extend stroke on-site to hit the exact required protrusion.
Pushing parts out of a machined pocket at differing depths using the external stop screw to set the precise end position.
To replace the discontinued SUJ32X75-40TC, order the direct replacement SAUJ32X75-40TC, which preserves the 32 mm bore, 75 mm nominal stroke, 40 mm adjust window, 1/8" port, and TC mounting. Choose the 40 mm adjust window if your fixture requires cutting the extend stroke down to a 35 mm minimum on-site. The TC mount utilizes SC-series accessories. Because this SKU has no magnet, you cannot add a switch; the SAUJ replacement with an -S suffix is required for CMSG/DMSG/EMSG sensing. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SUJ32X75-40TC is discontinued. The direct replacement is the SAUJ32X75-40TC, which matches the 32 mm bore, 75 mm stroke, 40 mm adjust window, 1/8" port, and TC mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors, while this legacy model used CS1-B/DS1-B.
The external stop screw provides a 40 mm adjust window, allowing you to shorten the 75 mm nominal extend stroke down to 35 mm on-site. The stop sets end position but is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ32X75-40TC replacement — usually within 7-8 hours.
