This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X335S, 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.
Airtac SU32~50 Standard Cylinder SU32X335S
The AirTAC SU32~50 Standard Cylinder SU32X335S is a double-acting profile-type standard cylinder with a Ø32mm bore and 335mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X335S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X335S
The AirTAC SU32X335S is a discontinued double-acting profile-type cylinder with a 32mm bore and 335mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this legacy unit with the SAU32X335S, a direct upgrade retaining the exact bore, stroke, force, and SC-series mounting footprint.
Because this SKU includes a magnet (-S), it originally used CS1-B/DS1-B switches; the SAU replacement transitions to modern CMSG/DMSG/EMSG sensors. The extruded aluminum profile is more compact than a standard ISO 15552 unit. The SAU family also introduces a SAUF variant with a built-in valve, an option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X335S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X335S 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.
Where the Airtac SU32~50 Standard Cylinder SU32X335S Is Used
Package Diverting
Actuates a routing gate on a packaging conveyor, relying on the 335mm stroke to clear the belt path.
Bin Push-Off
Transfers small inventory items from a staging shelf into a shipping tote with controlled air cushions.
Replacing the Airtac SU32~50 Standard Cylinder SU32X335S with the SAU32X335S
To replace this discontinued SU32X335S, order the SAU32X335S. Confirm the 1/8" port, M10x1.25 rod thread, and default PT threads. The -S magnet means you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. If you need higher force, the neighboring 40mm bore offers 628N push at 0.5MPa; if lower force is acceptable, check smaller options. At 335mm stroke, prevent rod bending by using an external guide to absorb side loads. This cylinder does not hold load without live air; use a pilot-operated check valve or external rod lock for drop prevention. The SAUF built-in-valve option can simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU32X335S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU32~50 Standard Cylinder SU32X335S FAQ
Yes, the SU32X335S is discontinued. The direct replacement is the SAU32X335S. It matches the 32mm bore, 335mm stroke, 402N force at 0.5MPa, 1/8" port, and SC-series mounting. You just swap the cylinder and update your sensors.
It provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because this is an -S model with a magnet, it used legacy CS1-B/DS1-B switches. The SAU32X335S replacement requires CMSG/DMSG/EMSG sensors instead.
