This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-50S in place of this model. 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 SUJ32X500-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X500-50S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X500-50S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 450-500 mm stroke. The nominal 500 mm is the maximum. At 32 mm it delivers 402 N push and 345 N pull at 0.5 MPa, features a 1/8" port, and uses a compact extruded aluminum barrel shorter than an ISO 15552 cylinder of the same bore. This discontinued SUJ model is replaced by the SAUJ32X500-50S.
The SAUJ32X500-50S is a drop-in replacement retaining the exact bore, stroke, force, port, and FA/LB mounting. For sizing, a safe working load is roughly 241 N (60% of the 402 N push at 0.5 MPa), translating to a 20 kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock for held loads. This -S model used legacy CS1-B/DS1-B sensors, whereas the SAUJ uses current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-50S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X500-50S produces the same force from the same bore — a true drop-in on output. 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.
A fixture needing precise depth control without swapping cylinders can use the 50 mm adjust window to tune the extend stroke on-site for different material thicknesses.
An end-of-line diverter can field-trim the 500 mm extend stroke by up to 50 mm to accommodate changing package sizes without reprogramming the motion controller.
A sorting lane uses the external stop screw to set exact ejection distances for various product lengths, ensuring gentle contact without hard mechanical stops.
To replace this discontinued unit, order the SAUJ32X500-50S, which matches the 32 mm bore, 500 mm max stroke, 1/8" port, and FA/LB mounting. The -50 adjust window lets you trim the extend stroke by up to 50 mm on-site, useful when a fixed SAU plus external stop would be cumbersome. If you need more force, the neighboring 40 mm bore provides 628 N push at 0.5 MPa; if less force is acceptable, there is no smaller standard SUJ bore, so confirm from datasheet. Because the stroke is 500 mm, add external guides to prevent rod bending under side loads. The -S suffix means this SUJ used CS1-B/DS1-B sensors; the SAUJ replacement requires CMSG/DMSG/EMSG switches.
Replacement checklist
Yes, the SUJ32X500-50S is discontinued. The exact drop-in replacement is the SAUJ32X500-50S, which matches the 32 mm bore, 500 mm stroke, 1/8" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The external stop screw provides a 50 mm adjust window, allowing you to shorten the 500 mm extend stroke down to 450 mm on-site. The stop sets end position but is not a load lock.
