This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X225TC, 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 SU50X225TC
The AirTAC SU32~50 Standard Cylinder SU50X225TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 225mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X225TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X225TC
The AirTAC SU50X225TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 225mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X225TC, a direct replacement retaining the exact bore, stroke, force, port size, and SC-series TC mounting interface.
Because this SKU lacks the -S magnet, it cannot accept a position sensor. The SAU upgrade introduces the SAUF built-in 4M solenoid valve variant, which the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X225TC 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 SAU50X225TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU50X225TC Is Used
Package Diversion
Actuates a routing gate on a 50kg capacity conveyor line, utilizing the 982N push force at 0.5MPa to reliably redirect heavy cartons.
Pallet Stop Gate
Controls a TC-mounted stopping mechanism at a palletizing station, handling standard loads within the 589N safe working limit.
Clamp Actuation
Drives a 225mm stroke clamping arm to secure medium-density workpieces during machining operations.
Replacing the Airtac SU32~50 Standard Cylinder SU50X225TC with the SAU50X225TC
To replace the SU50X225TC, order the SAU50X225TC. Verify your 1/4" port threads (PT, G, or NPT) and the M16x1.5 rod-end connection. The TC mounting accessory is retained from the SC-series. Since this is a non-magnet SKU, it cannot hold a sensor; if sensing is needed, you must upgrade to an -S SAU model and switch from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. At 225mm stroke, side-load risks are moderate, so ensure proper guide alignment to prevent rod bending. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock for held loads. Neighbouring bores: a 40mm bore yields 628N push @0.5MPa, while a 63mm bore yields 1559N.
Replacement checklist
- ✓ Same bore / stroke → SAU50X225TC
- ✓ 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 SU50X225TC FAQ
Yes, the SU50X225TC is discontinued. The direct replacement is the AirTAC SAU50X225TC. It shares the identical 50mm bore, 225mm stroke, 982N output force, 1/4" port, and SC-series TC mounting, so it fits the same application directly.
The 50mm bore provides 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 has no magnet (-S), so it cannot accept sensors; a legacy -S version used CS1-B/DS1-B switches, while the SAU replacement uses CMSG/DMSG/EMSG sensors.
