This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X350TC, 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 SU50X350TC
The AirTAC SU32~50 Standard Cylinder SU50X350TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 350mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X350TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X350TC
The AirTAC SU50X350TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 350mm stroke. It delivers 982N push force at 0.5MPa via a 1/4-inch port. AirTAC replaced this unit with the SAU50X350TC, a direct upgrade retaining the exact body, stroke, force, port size, and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept sensors. If sensing is needed on the SAU replacement, note the switch family changed from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. The SAU line also adds a SAUF valve-integrated variant the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X350TC 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 SAU50X350TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×350 | 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 SU50X350TC Is Used
Package Diverting
Pushes cartons across transfer belts using the 982N push force, while the 350mm extension reaches across a 300mm wide conveyor lane.
Pallet Push-Off
Stages goods at the end of packaging lines, with the TC mount providing a rigid pivot for horizontal sweeping motions.
Replacing the Airtac SU32~50 Standard Cylinder SU50X350TC with the SAU50X350TC
To replace this SU50X350TC, order the SAU50X350TC. Confirm the 50mm bore, 350mm stroke, 1/4-inch port (PT/G/NPT thread), M16x1.5 rod thread, and TC mounting. Since this SKU has no magnet, it cannot support a sensor. If you need position detection on the SAU, you must add the -S option and migrate to CMSG/DMSG/EMSG switches. For 350mm strokes, prevent rod bending by using an external guide to absorb side loads. If dropping air pressure risks load drift, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If more force is needed, step up to the 63mm bore (1559N at 0.5MPa); if less is needed, drop to 40mm (628N). The SAUF variant offers a built-in valve if you want to simplify plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU50X350TC
- ✓ 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 SU50X350TC FAQ
Yes, the SU50X350TC is discontinued. The direct replacement is the SAU50X350TC. It shares the identical 50mm bore, 350mm stroke, 982N force, 1/4-inch port, and TC mounting, so it fits the same application.
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, so it cannot accept sensors. The SAU replacement uses CMSG/DMSG/EMSG switches if you add the -S option.
