This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X710, 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 SU50X710
The AirTAC Airtac SU32~50 Standard Cylinder SU50X710 is a double-acting profile-type standard cylinder with a Ø50mm bore and 710mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X710, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X710
The AirTAC SU50X710 is a discontinued double-acting profile-type cylinder with a 50mm bore and 710mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this legacy unit with the SAU50X710, a direct upgrade retaining the exact body dimensions, stroke, force, and SC-series mounting hardware.
The SAU replacement modernizes sensing by using CMSG/DMSG/EMSG switches instead of the SU's older CS1-B/DS1-B units, and introduces the SAUF built-in-valve option the SU line lacked. Note this non-magnet SKU cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X710 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 SAU50X710 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 SU50X710 Is Used
Long-Stroke Diversion
Pushes packages across a transfer lane using the 710mm stroke, relying on the 982N thrust at 0.5MPa for steady actuation.
Pneumatic Press Ejection
Clears finished parts from a press bed, using the compact profile body to fit tight machinery footprints.
Replacing the Airtac SU32~50 Standard Cylinder SU50X710 with the SAU50X710
To replace the SU50X710, order the SAU50X710, confirming the 50mm bore, 710mm stroke, 1/4" port, and M16x1.5 rod thread. If moving down from a 63mm bore, the 50mm provides 982N push at 0.5MPa; stepping up to 63mm yields 1559N. Because this is a non-magnet SKU, it cannot support a sensor. The 710mm stroke demands an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X710
- ✓ 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 SU50X710 FAQ
Yes, the SU50X710 is discontinued. The direct replacement is the AirTAC SAU50X710. It matches the 50mm bore, 710mm stroke, 1/4" port, output force, and SC-series mounting, so it fits the same application without mechanical changes.
It delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. This specific SKU lacks a magnet and cannot accept a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches, whereas the legacy SU used CS1-B/DS1-B sensors.
