This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X130, 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 SU50X130
The AirTAC SU32~50 Standard Cylinder SU50X130 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 SAU50X130, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X130
The AirTAC SU50X130 is a discontinued double-acting profile-type cylinder featuring a 50mm bore, 130mm stroke, 20mm piston rod, and a 1/4" port. Delivering 982 N of push force at 0.5 MPa, it uses an extruded aluminum barrel that is more compact than a standard ISO 15552 unit of the same size. AirTAC replaced this EOL unit with the SAU50X130 direct replacement, matching the exact bore, stroke, output force, port size, and SC-series mounting.
Because this specific SKU lacks a magnet, it cannot accept a magnetic switch. The SAU50X130 upgrade introduces the current CMSG/DMSG/EMSG sensor family for -S variants and offers a new SAUF built-in 4M solenoid valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X130 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 SAU50X130 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 SU50X130 Is Used
Package Diverting
Drives short-stroke routing gates on production lines, providing fast 30-800 mm/s actuation to redirect goods efficiently.
Vertical Lifting
Handles elevation changes for bins up to 50 kg, relying on its 982 N push force at 0.5 MPa to raise materials between processing tiers.
Replacing the Airtac SU32~50 Standard Cylinder SU50X130 with the SAU50X130
To replace the discontinued SU50X130, order the SAU50X130 direct equivalent, verifying your 1/4" port, M16x1.5 rod thread, and SC-series mounting hardware. Since this non-magnetic SKU cannot accept sensors, adding position detection requires ordering the SAU50X130S and upgrading to CMSG/DMSG/EMSG switches. For loads needing 1374 N at 0.7 MPa, the 50mm bore is ideal, but if you need less force, step down to a 40mm bore; if you need more, step up to a 63mm bore. Remember that a plain cylinder drifts on air loss—the 21mm cushions only decelerate near stroke end—so use an external rod lock or pilot-operated check valve for secure load holding. For this 130mm stroke, ensure proper guide alignment to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU50X130
- ✓ 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 SU50X130 FAQ
Yes, the SU50X130 is discontinued. The direct replacement is the AirTAC SAU50X130. It matches the original 50mm bore, 130mm stroke, 982 N force, 1/4" port, and SC-series mounting, so it fits the same application without mechanical modifications.
The 50mm bore delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. This specific non-magnetic SKU cannot take a sensor; the SAU -S replacement uses CMSG/DMSG/EMSG switches.
