This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-30, 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 SUJ100X350-30 is a double-acting profile-type standard cylinder with a Ø100mm bore and 350mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X350-30, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X350-30 is a discontinued 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, giving a usable extend window of 320-350 mm. The nominal 350 mm stroke is the maximum. The 1/2" port, M20x1.5 rod thread, and 29 mm adjustable cushions handle heavy dynamics.
The direct replacement is the SAUJ100X350-30, retaining the same bore, stroke, force, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors, as this legacy model used CS1-B/DS1-B. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X350-30 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ100X350-30 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×350 | Stroke length in mm. |
| -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.
Allows operators to dial in the exact 320-350 mm extend position for pressing bearings without machining hard stops.
Adjusts the extend stroke on-site to deflect different package sizes on a heavy transfer line.
Sets a precise physical end position for pallets, with the 30 mm window accommodating various pallet heights.
To replace the discontinued SUJ100X350-30, swap directly to the SAUJ100X350-30 for identical 100 mm bore, 350 mm stroke, 30 mm adjust window, and 1/2" port. Choose the 30 mm adjust window if your end-of-stroke target varies by up to 30 mm. Use FA or LB mounting (SC-series compatible). This non-magnetic SKU cannot take a switch; the SAUJ uses CMSG/DMSG/EMSG sensors. At 350 mm stroke, support side loads with external guides to prevent rod bending.
Replacement checklist
Yes, the SUJ100X350-30 is discontinued. The direct replacement is the SAUJ100X350-30, which shares the same 100 mm bore, 350 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG sensors.
The double-acting double-rod cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa. The external stop screw trims the extend stroke by up to 30 mm on-site (usable 320-350 mm). The stop sets end position only; it is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ100X350-30 replacement — usually within 7-8 hours.
