This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X80, 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 SU32~50 Standard Cylinder SU32X80 is a double-acting profile-type standard cylinder with a Ø32mm bore and 80mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X80, which matches its bore, stroke, force and mounting.
The AirTAC SU32X80 is a discontinued double-acting profile-type cylinder featuring an extruded aluminum barrel and adjustable air cushions at both ends. Delivering 402 N push force at 0.5 MPa, it is replaced directly by the SAU32X80. This direct upgrade retains the exact 32 mm bore, 80 mm stroke, 1/8" port, and SC-series mounting compatibility.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU replacement also omits one but introduces compatibility with modern CMSG/DMSG/EMSG switches if you need sensing later.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X80 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAU32X80 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.
Uses the 402 N push force at 0.5 MPa to reliably push lightweight molded plastic parts out of a machining fixture.
Short 80 mm stroke actuates a diverter arm to sort small boxes on a conveyor line without taking up much space.
Compact profile body fits between tight shelving clearances to index storage bins forward on a roller track.
To replace this discontinued SU32X80, order the SAU32X80, confirming the 1/8" port, M10x1.25 rod thread, and PT/G/NPT thread choice. If sensing is needed, note the SAU uses CMSG/DMSG/EMSG switches. Sizing both ways: dropping to a smaller bore loses thrust, while stepping up to 40 mm yields 628 N at 0.5 MPa. This plain cylinder drifts on air loss—the cushion only decelerates—so use a rod lock for held loads. The SAUF variant adds a built-in valve the SU lacked.
Replacement checklist
Yes, the SU32X80 is discontinued. The direct replacement is the AirTAC SAU32X80. It shares the same 32 mm bore, 80 mm stroke, output force, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
It provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The cushion only decelerates near stroke end; it does not hold load on air loss, so use an external rod lock for vertical holding.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X80 replacement — usually within 7-8 hours.
