This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X120TC, 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 SU50X120TC
The AirTAC SU32~50 Standard Cylinder SU50X120TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 120mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X120TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X120TC
The AirTAC SU50X120TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 120mm stroke. It delivers 982 N push and 825 N pull at 0.5 MPa, utilizing a 1/4" port and M16x1.5 rod thread. AirTAC replaced this legacy unit with the SAU50X120TC, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensor. If sensing is needed, the SAU replacement requires the current CMSG/DMSG/EMSG switch family (the SU line used legacy CS1-B/DS1-B). The SAU also introduces a SAUF variant with a built-in 4M solenoid valve. Note that standard cylinders drift without live air; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X120TC 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 SAU50X120TC 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 SU50X120TC Is Used
Package Diverting
Pushes parcels off a belt line using the 982 N push force at 0.5 MPa, with the TC mount allowing pivoting alignment.
Clamp Actuation
Secures workpieces during machining, providing 825 N pull force while relying on external check valves for safety.
Stopper Gate
Raises and lowers pallet stops using the 120mm stroke, easily fitting into compact machinery profiles.
Replacing the Airtac SU32~50 Standard Cylinder SU50X120TC with the SAU50X120TC
To replace the SU50X120TC, order the SAU50X120TC, confirming the 50mm bore, 120mm stroke, 1/4" port (PT/G/NPT), and TC mounting. Since this SKU has no magnet (-S), it cannot support sensing; if you need position detection, the SAU upgrade uses CMSG/DMSG/EMSG switches. For force context, the 50mm bore yields 982 N push at 0.5 MPa. If undersizing, a 40mm bore provides 628 N; if oversizing, a 63mm bore offers 1559 N. For automated cycling, consider the SAUF variant with its integrated valve. Remember, the air cushion only decelerates the piston; it does not hold the load. To prevent drift on air loss, install an external rod lock or pilot-operated check valve. As the 120mm stroke is under 300mm, rod bending is minimal, but ensure the TC mount aligns to avoid side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X120TC
- ✓ 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 SU50X120TC FAQ
Yes, the SU50X120TC is discontinued. The direct replacement is the AirTAC SAU50X120TC. It matches the 50mm bore, 120mm stroke, 982 N force, 1/4" port, and TC mounting. The SAU body is fully compatible with existing SC-series accessories.
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa push is 1374 N, and the theoretical max is 200 kgf at 1.0 MPa. It cannot hold a load on air loss; the cushion only decelerates. Use an external rod lock for holding. Also, this no-magnet SKU cannot take sensors.
