This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X100-40, 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 SUJ100X100-40 is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X100-40, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X100-40 is a discontinued double-acting double-rod profile cylinder with an on-site stroke-trim window. An external stop screw shortens the extend stroke by up to 40 mm, giving a usable extend range of 60 to 100 mm. The nominal 100 mm stroke is the maximum. It features a 1/2 inch port and a 25 mm rod.
The direct replacement is the SAUJ100X100-40, sharing the same bore, stroke, force, port, and SC-series mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

The SAUJ100X100-40 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.
Allows operators to dial in the exact 60 to 100 mm extend position for inserting bearings without machining fixed spacers.
Adjusts the extend end-point on-site to accommodate different box heights on a packaging line using a single actuator setup.
Provides a field-tunable hard stop for sorting diverts, letting maintenance shorten the stroke by up to 40 mm as layout needs change.
To replace the discontinued SUJ100X100-40, select the SAUJ100X100-40, which is a direct retaining the 100 mm bore, 100 mm nominal stroke, 40 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 40 mm adjust window when you need to trim the extend stroke down to 60 mm on-site, which is often more efficient than fitting a fixed-stroke SAU cylinder with an external mechanical stop. Because this specific SKU lacks a magnet (-S), it cannot take a magnetic switch; the SAUJ replacement uses CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent guide bushing wear.
Replacement checklist
Yes, the SUJ100X100-40 is discontinued. The direct replacement is the SAUJ100X100-40, which matches the 100 mm bore, 100 mm stroke, 40 mm adjust window, 1/2 inch port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 100 mm bore double-acting double-rod cylinder pushes 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa, with a pull of 3681 N at 0.5 MPa. The external stop screw window is 40 mm, allowing the extend stroke to be shortened from the 100 mm maximum down to 60 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 SAUJ100X100-40 replacement — usually within 7-8 hours.
