This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X165S, 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 SU50X165S
The AirTAC SU32~50 Standard Cylinder SU50X165S is a double-acting profile-type standard cylinder with a Ø50mm bore and 165mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X165S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X165S
The AirTAC SU50X165S is a discontinued double-acting profile-type cylinder with a 50mm bore and 165mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced it with the SAU50X165S, a direct upgrade retaining the exact bore, stroke, output force, and SC-series mounting footprint.
The SAU upgrade switches the -S magnet compatibility from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in 4M solenoid valve variant the SU line lacked. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X165S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X165S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU50X165S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×165 | Stroke length in mm. |
| -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.
Where the Airtac SU32~50 Standard Cylinder SU50X165S Is Used
Package Diverting
Pushes cartons at 30-800 mm/s on packaging lines, using the 982N push force to redirect items without stalling.
Pallet Stopper Gate
Acts as a compact 50mm bore stop gate for light pallets, fitting neatly into existing SC-series bracket mounts.
Replacing the Airtac SU32~50 Standard Cylinder SU50X165S with the SAU50X165S
To replace this SU50X165S, order the SAU50X165S. Confirm your 1/4" port, M16x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB) carry over directly. Because this SKU includes the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. For loads needing 1374N at 0.7MPa, the 50mm bore fits; if less force is needed, a 40mm bore offers 628N push. A plain cylinder drifts on air loss—the cushions only decelerate—so add an external rod lock for vertical holding. At 165mm stroke, side-load is low, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same bore / stroke → SAU50X165S
- ✓ 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 SU50X165S FAQ
Yes, the SU50X165S is discontinued. The direct replacement is the AirTAC SAU50X165S. It shares the same 50mm bore, 165mm stroke, 1/4" port, and SC-series mounting accessories. You simply order the SAU equivalent.
The SAU50X165S matches the SU force ratings: 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a 200kgf max at 1.0MPa. Because your old model has the -S magnet, note that the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
