This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X160, 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 SU32X160
The AirTAC Airtac SU32~50 Standard Cylinder SU32X160 is a double-acting profile-type standard cylinder with a Ø32mm bore and 160mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X160, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X160
The AirTAC SU32X160 is a discontinued double-acting profile cylinder featuring a 32mm bore and 160mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore while delivering 402 N of push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU32X160, a direct upgrade retaining the exact body dimensions, 1/8" port, M10x1.25 rod thread and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU32X160 replacement modernizes sensing with CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B) and introduces the SAUF built-in 4M valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X160 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 SAU32X160 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 SU32X160 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to eject light machined components from a fixture without damaging the surface.
Package Diverting
Cycles at 30-800 mm/s to push small cartons off a packaging line, fitting easily into tight transfer spaces.
Clamp Actuation
Provides reliable clamping pressure for lightweight jig assemblies where a 20 kg vertical lift margin is sufficient.
Replacing the Airtac SU32~50 Standard Cylinder SU32X160 with the SAU32X160
To replace this SU32X160 with the SAU32X160, verify your 32mm bore, 160mm stroke, 1/8" port (PT/G/NPT) and SC-series mounting hardware. Since this non-magnetic SKU cannot take a switch, order the SAU32X160-S if you need position sensing. Note the SAU upgrade shifts sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. For higher loads, the 40mm bore yields 628 N push at 0.5 MPa. A plain cylinder drifts on air loss, so add an external rod lock for vertical holding. The SAUF variant integrates a valve if you need self-switching. At 160mm stroke, guide rods prevent side-load bending.
Replacement checklist
- ✓ Same bore / stroke → SAU32X160
- ✓ 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 SU32X160 FAQ
Yes, the AirTAC SU32X160 is discontinued. The direct replacement is the SAU32X160, which shares the same 32mm bore, 160mm stroke, 402 N force, 1/8" port and SC-series mounting.
It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU32X160-S replacement uses CMSG/DMSG/EMSG switches.
