This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X165, 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 SU50X165
The AirTAC Airtac SU32~50 Standard Cylinder SU50X165 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 SAU50X165, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X165
The AirTAC SU50X165 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 this unit with the SAU50X165, a direct alternative retaining the exact body dimensions, output, and SC-series mounting.
This legacy SKU lacks a magnet, so it cannot accept position sensors. If sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG switches. Note that standard cylinders drift without air; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X165 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 SAU50X165 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 SU50X165 Is Used
Package Diverting
Actuates diverting arms on 50kg class packaging lines using the 982N push force at 0.5MPa to push cartons off the main belt.
Pallet Stop Gate
Controls pallet flow at accumulation zones with a 165mm stroke, handling loads safely within the 589N working limit.
Clamp Actuation
Secures medium workpieces during machining, relying on adjustable 21mm cushions to decelerate the 20mm rod smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU50X165 with the SAU50X165
To replace the SU50X165, order the SAU50X165 direct equivalent. Verify your 1/4" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC). Because this specific SKU has no magnet, it cannot support switches; if you require sensing, the SAU upgrade uses CMSG/DMSG/EMSG sensors. For higher loads, the 63mm bore yields 1559N push at 0.5MPa, while a 40mm bore offers 628N. At 165mm stroke, side-load is minimal, but always guide the rod to prevent bending. The cylinder does not hold load on air loss—add a pilot-operated check valve. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X165
- ✓ 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 SU50X165 FAQ
Yes, the AirTAC SU50X165 is discontinued. The direct replacement is the SAU50X165. It matches the 50mm bore, 165mm stroke, 982N force, 1/4" port, and SC-series mounting accessories perfectly.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take sensors. The SAU replacement supports CMSG/DMSG/EMSG switches.
