This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X370SH, 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 SU50X370SH
The AirTAC SU32~50 Standard Cylinder SU50X370SH 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 SAU50X370SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X370SH
The AirTAC SU50X370SH is a discontinued double-acting profile-type cylinder with a 50mm bore, 370mm stroke, and a high-temperature Viton H seal. It delivers 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this unit with the SAU50X370SH, a direct upgrade retaining the exact bore, stroke, force, port, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S magnet model, and adds a SAUF built-in-valve option the SU line lacked. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X370SH 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 SAU50X370SH 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 SU50X370SH Is Used
High-Temp Diverting
Actuates diverter arms on hot-end conveyor lines, using the Viton H seal to withstand ambient temperatures up to 150 C while pushing packages with 982 N force.
Oven Door Automation
Opens and closes industrial curing oven doors, where the 370mm stroke provides the necessary reach and the high-temp seal survives radiated heat without degrading.
Replacing the Airtac SU32~50 Standard Cylinder SU50X370SH with the SAU50X370SH
To replace this SU50X370SH, order the SAU50X370SH direct equivalent, verifying the 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this is a -S magnet model, you must switch from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors. The Viton H seal on this unit handles 0-150 C environments; confirm the SAU maintains this high-temp option. At 0.5 MPa, the 50mm bore yields 982 N push and 825 N pull force; if undersized, the 63mm bore provides 1559 N push. For the 370mm stroke, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates the piston; it does not hold the load on air loss, so add an external rod lock or pilot-operated check valve for vertical holding. If valve integration is needed, explore the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X370SH
- ✓ 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 SU50X370SH FAQ
Yes, the SU50X370SH is discontinued. The direct replacement is the AirTAC SAU50X370SH. It shares the same 50mm bore, 370mm stroke, 1/4" port, output force, and SC-series mounting. You simply order the SAU model for an identical mechanical fit.
The 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf theoretical max at 1.0 MPa. Because your old model has a -S magnet, the SAU replacement requires upgrading from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family.
