This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X520SH, 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 SU50X520SH
The AirTAC SU32~50 Standard Cylinder SU50X520SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 520mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X520SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X520SH
The AirTAC SU50X520SH is a discontinued double-acting profile-type cylinder with a 50mm bore and 520mm stroke. Built for high-temperature environments, it features a Viton H seal rated for 0 to 150 C. It delivers 982 N push force at 0.5 MPa and uses a 1/4" port. AirTAC replaced this legacy unit with the SAU50X520SH, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting.
Because the SU50X520SH has a built-in magnet (-S), it originally used CS1-B/DS1-B switches; the SAU replacement upgrades you to current CMSG/DMSG/EMSG sensors. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X520SH 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 SAU50X520SH 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 SU50X520SH Is Used
High-Temperature Ejection
Uses the Viton H seal to survive 150 C ambient heat near injection moulding machines while ejecting finished parts with 982 N of force.
Extended Transfer Pushing
The 520mm stroke spans wide gaps to index heavy pallets along an assembly line, relying on external guides to prevent rod bending.
Material Diversion
Actuates diverter arms on packaging conveyors, where the magnetic piston tracks position via CS1-B switches to confirm stroke completion.
Replacing the Airtac SU32~50 Standard Cylinder SU50X520SH with the SAU50X520SH
To replace this discontinued SU50X520SH, order the SAU50X520SH. Confirm the 1/4" port, M16x1.5 rod thread, and PT/G/NPT thread choice match your fittings. Because this SKU includes a magnet (-S), note the sensor family changes from legacy CS1-B/DS1-B to modern CMSG/DMSG/EMSG switches on the SAU. The Viton H high-temp seal (-H) carries over directly. If you need integrated flow control, the SAU line offers a SAUF variant with a built-in 4M solenoid valve the SU lacked. With a 520mm stroke, prevent rod bending by guiding the load externally to avoid side-load forces. For sizing alternatives, a 40mm bore gives 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N. Remember, a standard cylinder drifts without live air; the cushions only decelerate. Use an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X520SH
- ✓ 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 SU50X520SH FAQ
Yes, the AirTAC SU50X520SH is discontinued. The direct replacement is the SAU50X520SH. It matches the 50mm bore, 520mm stroke, 1/4" port, output force, and SC-series mounting. The main upgrade is that your legacy CS1-B/DS1-B sensors must be replaced with CMSG/DMSG/EMSG switches on the new SAU model.
The 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa. Standard temperature is -20 to +70 C, but this -H variant uses a Viton seal to handle 0 to 150 C environments. Speed ranges from 30-800 mm/s.
