This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X370, 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 SU50X370
The AirTAC SU32~50 Standard Cylinder SU50X370 is a double-acting profile-type standard cylinder with a Ø50mm bore and 370mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X370, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X370
The AirTAC SU50X370 is a discontinued double-acting profile-type standard cylinder with a 50mm bore and 370mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X370, a direct replacement retaining the exact bore, stroke, output force, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade introduces CMSG/DMSG/EMSG switch compatibility for its -S variants, plus a SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X370 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 SAU50X370 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 SU50X370 Is Used
Package Diverting
Actuates diverting arms on packaging lines, utilizing the 370mm stroke to push cartons smoothly between adjacent conveyor belts.
Pallet Stopping
Serves as a pneumatic stop gate in low-profile warehouse roller conveyors, holding standard pallets securely during processing.
Component Ejection
Ejects machined parts from a fixture, providing reliable 982N push force at 0.5MPa to clear stamped metal components.
Replacing the Airtac SU32~50 Standard Cylinder SU50X370 with the SAU50X370
To replace the SU50X370, order the SAU50X370, confirming the 50mm bore, 370mm stroke, M16x1.5 rod thread, 1/4" port (PT/G/NPT), and SC-series mounting. If moving down, a 40mm bore yields 628N push at 0.5MPa; if moving up, a 63mm bore provides 1559N. Since this non-magnet SKU cannot take a switch, order an SAU50X370S if you need sensing (using modern CMSG/DMSG/EMSG sensors). For the 370mm stroke, use external guides to prevent rod bending under side loads. Note that cushions only decelerate; use a rod lock or pilot check valve to hold loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X370
- ✓ 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 SU50X370 FAQ
Yes, the SU50X370 is discontinued. The direct replacement is the AirTAC SAU50X370. It matches the 50mm bore, 370mm stroke, 982N force, 1/4" port, and SC-series mounting, so it drops right into the same application.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. This specific SKU has no magnet, so it cannot take a sensor. The SAU50X370S upgrade supports modern CMSG/DMSG/EMSG switches.
