This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X310S, 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 SU32X310S is a double-acting profile-type standard cylinder with a Ø32mm bore and 310mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X310S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X310S is a discontinued double-acting profile-type cylinder with a 32mm bore and 310mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8" port. The direct replacement is the SAU32X310S, matching the bore, stroke, force, port and SC-series mounts.
The SAU upgrade switches the legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors, and introduces the SAUF valve-integrated variant. The 310mm stroke requires external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X310S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X310S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Provides 402N push at 0.5MPa to eject machined small parts from a fixture, utilizing the 310mm stroke to clear the work area completely.
Handles the sorting of lightweight inventory trays by extending 310mm to push items into designated chutes at speeds up to 800mm/s.
To replace this discontinued SU32X310S, order the SAU32X310S direct equivalent. Verify your 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If you need integrated air control, explore the SAUF variant which features a built-in 4M solenoid valve. For loads needing 563N at 0.7MPa, this 32mm bore fits, but if you need 628N consider the 40mm bore. At 310mm stroke, use external guides to prevent rod bending. Note that air cushions only decelerate; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
Yes, the AirTAC SU32X310S is discontinued. The direct replacement is the SAU32X310S, which shares the same 32mm bore, 310mm stroke, 1/8" port, output force, and SC-series mounting accessories.
It delivers 402N push and 345N pull at 0.5MPa, 563N at 0.7MPa, and a maximum theoretical force of 82kgf at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the new SAU unit.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X310S replacement — usually within 7-8 hours.
