This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X25-10LB, 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 SUJ32X25-10LB is a double-acting profile-type standard cylinder with a Ø32mm bore and 25mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X25-10LB, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X25-10LB is a double-acting, double-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 15-25 mm extend window from the 25 mm nominal maximum. This compact profile body is shorter than an ISO 15552 cylinder of the same bore.
This SUJ model is discontinued and the direct replacement is the SAUJ32X25-10LB, retaining the same bore, stroke, force, and LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. Note that this specific SKU lacks a magnet and cannot take a magnetic switch.

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.
Ideal for clamping small parts where the exact extend position must be trimmed by up to 10 mm on-site to accommodate varying material thicknesses without changing the cylinder.
Useful in tight machinery layouts where a short 15-25 mm extend stroke is needed to eject lightweight components, leveraging the compact profile body to save space.
Suitable for applying a gauging force up to 402 N, where the external stop screw allows precise field adjustment of the extend end position for inspection stops.
To replace the discontinued SUJ32X25-10LB, specify the SAUJ32X25-10LB direct equivalent, which matches the 32 mm bore, 25 mm stroke, 10 mm adjust window, 1/8" port, and LB mounting. The 10 mm adjust window is ideal for fine-tuning the extend end position in tight spaces. Because this SKU has no magnet, you cannot fit sensors; if sensing is needed, select an SAUJ with the -S option for CMSG/DMSG/EMSG compatibility. The stop screw sets the end position but is not a lock; for load holding on air loss, use an external rod lock or pilot-operated check valve. Since the stroke is under 300 mm, side-load concerns are minimal.
Replacement checklist
Yes, the AirTAC SUJ32X25-10LB is discontinued. The direct replacement is the SAUJ32X25-10LB. It offers the same 32 mm bore, 25 mm nominal stroke, 10 mm adjust window, 1/8" port, and LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 10 mm adjustment window, allowing the extend stroke to be shortened from the 25 mm nominal maximum down to 15 mm on-site. 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 SAUJ32X25-10LB replacement — usually within 7-8 hours.
