This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X310S, 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 SU50X310S
The AirTAC SU32~50 Standard Cylinder SU50X310S is a double-acting profile-type standard cylinder with a Ø50mm bore and 310mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X310S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X310S
The AirTAC SU50X310S is a discontinued double-acting profile-type cylinder with a 50mm bore and 310mm stroke. Delivering 982N push force at 0.5MPa, it features an extruded aluminum barrel and adjustable cushions. AirTAC replaced it with the SAU50X310S direct replacement, matching the exact bore, stroke, 1/4" port, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S model. The SAU line also adds a SAUF valve-integrated variant. Note that air cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X310S 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 SAU50X310S 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 SU50X310S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×310 | 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 SU50X310S Is Used
Package Diverting
Pushes cartons at 90 degrees on a packaging line using the 982N push force, with the 310mm stroke clearing the belt width.
Component Ejection
Ejects machined parts from a fixture, where the compact profile body saves space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU50X310S with the SAU50X310S
To replace this SU50X310S, order the SAU50X310S. Confirm the 50mm bore, 310mm stroke, M16x1.5 rod thread, 1/4" port (PT/G/NPT), and SC-series mounting. Because this -S SKU has a magnet, you must switch from CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. The 50mm bore yields 982N push at 0.5MPa; if undersized, the 63mm bore provides 1559N. For the 310mm stroke, use external guides to prevent rod bending under side loads. The cylinder drifts without air; add a pilot-operated check valve for load holding. If valve integration is needed, explore the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X310S
- ✓ 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 SU50X310S FAQ
Yes, the AirTAC SU50X310S is discontinued. The direct replacement is the SAU50X310S, which shares the same 50mm bore, 310mm stroke, 1/4" port, and SC-series mounting accessories.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a 200kgf max at 1.0MPa. The -S magnet on this SU worked with CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
