This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X75-30S, 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 SUJ100X75-30S is a double-acting profile-type standard cylinder with a Ø100mm bore and 75mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X75-30S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X75-30S is a 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 45-75 mm extend window from the 75 mm nominal maximum. The bore dictates a 1/2" port, a Ø25 mm piston rod, and M20x1.5 rod threads, operating at 30-800 mm/s with 29 mm adjustable air cushions.
This SUJ100X75-30S unit is discontinued and drops in directly with the SAUJ100X75-30S, retaining the exact bore, stroke, force, port, and FA/LB mounting. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAUJ replacement migrates to current CMSG/DMSG/EMSG sensors. Note the stop screw sets end position only—it is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X75-30S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ100X75-30S 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.
Parts pushing stations that require on-site stroke tuning to accommodate varying product widths without swapping the entire cylinder.
Routing mechanisms on packaging lines where the external stop screw trims the extend stroke by up to 30 mm to handle different carton sizes.
End-of-line pallet stops needing precise end-position adjustment in the field to align with varying pallet heights.
To replace the discontinued SUJ100X75-30S, order the direct replacement SAUJ100X75-30S, which matches the 100 mm bore, 75 mm nominal stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. Select the -30 adjust window when your assembly requires field tuning between 45 and 75 mm. Because this unit has the -S magnet, you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load guidance to prevent rod binding.
Replacement checklist
Yes, the SUJ100X75-30S is discontinued. The direct replacement is the SAUJ100X75-30S, which shares the same 100 mm bore, 75 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also offers the SAUF built-in-valve variant the SU line lacked. If your unit has the -S magnet, upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable extend window of 45-75 mm. The stop sets end position only and is not a load lock; use an external rod lock for held loads.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ100X75-30S replacement — usually within 7-8 hours.
