This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X850SH, 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 SU32~50 Standard Cylinder SU32X850SH is a double-acting profile-type standard cylinder with a Ø32mm bore and 850mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X850SH, which matches its bore, stroke, force and mounting.
The AirTAC SU32X850SH is a discontinued double-acting profile-type cylinder with a 32mm bore and 850mm stroke. It delivers 402N push force at 0.5MPa and features a 1/8" port. The direct replacement is the SAU32X850SH, matching the exact bore, stroke, output force, port size, and SC-series mounting.
This unit includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF valve-integrated option. The -H Viton seal extends operating temperature to 0-150C.

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.
Actuates diverter arms on hot-end conveyor lines using the Viton -H seal to withstand 150C ambient heat while pushing light packages.
Drives long-travel pneumatic transfer carts between workstations, relying on adjustable 21mm cushions to decelerate at stroke ends.
To replace this SU32X850SH, order the SAU32X850SH direct equivalent, verifying the 32mm bore, 850mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because the -S magnet is present, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. The -H Viton seal is required for 0-150C high-temperature environments. If sizing down, a 32mm bore at 0.5MPa gives 402N push; if sizing up, consider larger bores for more thrust. A plain cylinder does not hold load without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for holding. At 850mm stroke, prevent rod bending by supporting the load with external guides to minimize side loads.
Replacement checklist
Yes, the AirTAC SU32X850SH is discontinued. The direct replacement is the SAU32X850SH. It matches the original 32mm bore, 850mm stroke, 402N force, 1/8" port, and SC-series mounting. You must upgrade your sensors, as the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a maximum theoretical force of 82kgf at 1.0MPa. The -H Viton seal allows operation from 0 to 150C. The cylinder speed ranges from 30-800mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X850SH replacement — usually within 7-8 hours.
