This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X75-30, 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 SUJ100X75-30 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 SAUJ100X75-30, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X75-30 is a discontinued double-acting double-rod profile cylinder with a 75 mm nominal stroke and a 30 mm adjustable-stroke window. An external stop screw lets you trim the extend stroke on-site by up to 30 mm, giving a usable extend range of 45-75 mm. The stop sets the end position but is not a load lock; use an external rod lock for held loads. This 100 mm bore unit features a 1/2" port, a 25 mm rod, M20x1.5 rod thread, and 29 mm adjustable cushions.
The direct replacement is the SAUJ100X75-30, retaining the same bore, stroke, force, port, and FA/LB mounting. This SKU lacks a magnet (-S omitted) and cannot take a magnetic switch. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches, and the compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

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

The SAUJ100X75-30 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.
Sheet metal stamping fixtures needing field stroke tuning to accommodate different material thicknesses without swapping the entire cylinder.
Package routing gates that require precise extend endpoint trimming on-site to handle varying box sizes on a shared line.
Palletizing cells where the extend stroke must be dialed in by up to 30 mm to establish exact stacking heights for mixed product runs.
To replace the discontinued SUJ100X75-30, order the direct replacement SAUJ100X75-30, which matches the 100 mm bore, 75 mm nominal stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, note the 80 mm neighbour bore provides less force, while larger bores add bulk. Choose the 30 mm adjust window if your fixture needs on-site extend tuning between 45 and 75 mm; the external stop sets end position but will not hold a load without live air. Because this specific SKU has no magnet, it cannot accept a sensor; the SAUJ replacement requires CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent rod bearing wear. Mounting compatibility is strictly with the AirTAC SC series.
Replacement checklist
Yes, the SUJ100X75-30 is discontinued. The direct replacement is the SAUJ100X75-30, which matches the 100 mm bore, 75 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 30 mm adjust window allows trimming the 75 mm extend stroke down to 45 mm on-site. The stop screw sets end position but is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ100X75-30 replacement — usually within 7-8 hours.
