This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X485S, 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 SU32X485S is a double-acting profile-type standard cylinder with a Ø32mm bore and 485mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X485S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X485S is a discontinued double-acting profile cylinder featuring a 32mm bore and 485mm stroke. It delivers 402N push and 345N pull at 0.5MPa. AirTAC replaced this unit with the SAU32X485S, a direct equivalent sharing the same 1/8" port, M10x1.25 rod thread, and SC-series mounting.
This compact extruded-aluminum body is shorter than an ISO 15552 cylinder of the same bore. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF valve-integrated option absent in the SU line.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X485S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X485S 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.
Ideal for pushing light parts out of machining fixtures using a safe 241N working load over the 485mm travel distance.
Actuates routing gates on compact conveyors, where the shorter profile body saves space without sacrificing the 402N push force.
Handles vertical lifting of 20kg trays in automated storage systems, guided externally to prevent rod bending on long strokes.
To replace this discontinued SU32X485S, order the SAU32X485S. Verify your 1/8" port thread (PT, G, or NPT) and SC-series mounting (LB, FA, FB, CA, CB, TC). Because the -S magnet uses legacy CS1-B/DS1-B switches, you must migrate to CMSG/DMSG/EMSG sensors on the SAU. At 0.5MPa, push is 402N (pull 345N); if undersized, a 40mm bore yields 628N push. The 485mm stroke requires external guides to prevent rod bending under side loads. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. The SAUF variant offers a built-in valve if needed.
Replacement checklist
Yes, the SU32X485S is discontinued. The direct replacement is the AirTAC SAU32X485S. It matches the 32mm bore, 485mm stroke, 402N force, 1/8" port, and SC-series mounting. The main change is that the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 32mm bore has a 1/8" port. At 0.5MPa it provides 402N push and 345N pull. At 0.7MPa push is 563N, and at 0.9MPa it is 724N. The theoretical maximum force is 82kgf at 1.0MPa. Operating speed is 30-800mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X485S replacement — usually within 7-8 hours.
