This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X80TC, 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 SU50X80TC
The AirTAC SU32~50 Standard Cylinder SU50X80TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 80mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X80TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X80TC
The AirTAC SU50X80TC is a discontinued double-acting profile-type cylinder with an 80 mm stroke and 50 mm bore. It delivers 982 N push force at 0.5 MPa via a 1/4 inch port. AirTAC replaced this unit with the SAU50X80TC, a direct alternative retaining the exact stroke, force, port size, and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept position sensors. The SAU upgrade also transitions to CMSG/DMSG/EMSG switches for magnetized variants, and introduces a SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X80TC 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 SAU50X80TC 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 SU50X80TC Is Used
Package Diversion
Actuates a sorting flap on a conveyor belt to push 50 kg parcels into secondary lanes using a safe 589 N working load.
Pallet Stop Gate
Controls a TC-mounted stopper gate on a roller conveyor, handling repetitive 80 mm strokes to regulate pallet flow.
Clamp Actuation
Secures medium workpieces in a machining fixture, delivering 982 N of clamping force at 0.5 MPa operating pressure.
Replacing the Airtac SU32~50 Standard Cylinder SU50X80TC with the SAU50X80TC
To replace the SU50X80TC, order the SAU50X80TC ensuring your 1/4" port threads (PT/G/NPT) and TC mounting match. If stepping up, a 63 mm bore yields 1559 N push at 0.5 MPa; stepping down to 40 mm provides 628 N. Note this non-magnetic SKU cannot support sensors, whereas a future -S SAU requires CMSG/DMSG/EMSG switches instead of legacy CS1-B/DS1-B. For held loads, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If needing integrated control, explore the SAUF valve variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X80TC
- ✓ 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 SU50X80TC FAQ
Yes, the SU50X80TC is discontinued. The direct replacement is the AirTAC SAU50X80TC, which shares the identical 50 mm bore, 80 mm stroke, 1/4" port, and TC mounting.
It provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf maximum at 1.0 MPa. This specific SKU has no magnet and cannot take sensors; magnetized SAU replacements use CMSG/DMSG/EMSG switches.
