This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X130S, 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 SU50X130S
The AirTAC SU32~50 Standard Cylinder SU50X130S is a double-acting profile-type standard cylinder with a Ø50mm bore and 130mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X130S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X130S
The AirTAC SU50X130S is a discontinued double-acting profile-type cylinder with a 50mm bore and 130mm stroke. Delivering 982N push force at 0.5MPa, it uses an extruded aluminium barrel that is more compact than an ISO 15552 cylinder of the same size. The direct replacement is the SAU50X130S, matching the bore, stroke, output force, 1/4-inch port and SC-series mounting.
Because this SKU includes a magnet (-S), it originally used CS1-B/DS1-B switches; the SAU successor upgrades to CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU family lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X130S 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 SAU50X130S 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 SU50X130S Is Used
Package Diverting
Pushes cartons at 30-800 mm/s on packaging lines, using the 982N thrust at 0.5 MPa to deflect medium-weight goods smoothly.
Pallet Stopper
Acts as a pneumatic stop for pallets, where the 50kg safe vertical lift capacity and compact profile body fit tight conveyor frames.
Clamp Actuation
Secures workpieces during machining, relying on the 825N pull force at 0.5 MPa and adjustable 21mm cushions to prevent end-impact.
Replacing the Airtac SU32~50 Standard Cylinder SU50X130S with the SAU50X130S
To replace this SU50X130S, order the SAU50X130S. Confirm the 1/4-inch port, M16x1.5 rod thread, PT/G/NPT thread preference, and SC-series mounting (LB/FA/FB/CA/CB). The -S magnet means you must change sensors: the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG on the SAU. For loads needing holding on air loss, add an external rod lock or pilot-operated check valve, as the 21mm adjustable cushion only decelerates. If sizing neighbours, the 40mm bore yields 628N push at 0.5MPa, while the 63mm bore gives 1559N. The 130mm stroke is under the 1200mm max, so no side-load guide is critical, but always prevent rod bending. Consider the SAUF if you want integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU50X130S
- ✓ 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 SU50X130S FAQ
Yes, the AirTAC SU50X130S is discontinued and end-of-life. The direct replacement is the SAU50X130S. It shares the same 50mm bore, 130mm stroke, 982N force, 1/4-inch port and SC-series 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 200kgf max at 1.0MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches do not fit the replacement; the SAU50X130S uses current CMSG/DMSG/EMSG sensors.
