This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X70-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X70-30 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 SUJ32X70-30 is a double-acting profile-type standard cylinder with a Ø32mm bore and 70mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X70-30, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X70-30 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 40-70 mm extension out of the 70 mm nominal maximum. The extruded aluminum profile barrel is more compact than an ISO 15552 unit of the same bore. This 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa, rising to 563 N at 0.7 MPa. It uses a 1/8" port and M10x1.25 rod thread.
Because the SUJ series is discontinued, the exact drop-in replacement is the SAUJ32X70-30, which retains the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy SUJ used CS1-B/DS1-B switches. For sizing, the 402 N push at 0.5 MPa implies a safe working load of roughly 241 N (about 60 percent of capacity) and a vertical lift capability of approximately 20 kg with a 2:1 safety margin. Note this non-magnet SKU cannot take a switch, and the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X70-30 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ32X70-30 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.
Feed parts of differing lengths on a single station by dialing the extend stroke down 30 mm on-site, avoiding the need to swap entire cylinders between product changeovers.
Tune the actuation reach of a routing flap precisely to the conveyor edge, allowing on-site stroke trimming to compensate for belt wear or varying package widths.
Set the exact extend endpoint for a sealing or folding head to prevent crushing delicate packaging, using the stop screw to define the final position mechanically.
To replace the discontinued SUJ32X70-30, order the drop-in SAUJ32X70-30, which matches the 32 mm bore, 70 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighboring 40 mm bore yields 628 N push at 0.5 MPa if you need more force, while the 32 mm bore itself provides 402 N push at 0.5 MPa. Choose the 30 mm adjust window if you need to field-tune the extend stroke down to a 40 mm minimum; this is often preferable to a fixed SAU plus an external stop because it saves space and avoids extra hardware. Mounting is compatible with the AirTAC SC series only. Since this is a non-magnet SKU, it cannot accept a sensor; if sensing is required, move to the SAUJ and select CMSG/DMSG/EMSG switches (the SUJ used legacy CS1-B/DS1-B). For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. Remember that the stop screw sets end position but does not lock the load; for held loads without live air, specify an external rod lock or pilot-operated check valve.
Replacement checklist
Yes, the AirTAC SUJ32X70-30 is discontinued. The exact drop-in replacement is the SAUJ32X70-30, which matches the 32 mm bore, 70 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B 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 30 mm adjust window, allowing you to shorten the 70 mm nominal extend stroke down to a 40 mm usable minimum. The stop sets end position but is not a load lock.
