This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X500SH, 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 SU50X500SH
The AirTAC SU32~50 Standard Cylinder SU50X500SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 500mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X500SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X500SH
The AirTAC SU50X500SH is a discontinued double-acting profile cylinder with a 50mm bore and 500mm stroke. It delivers 982 N push and 825 N pull at 0.5 MPa, utilizing a 1/4" port and M16x1.5 rod thread. AirTAC replaced this unit with the SAU50X500SH, a direct upgrade retaining the exact bore, stroke, force, port, and SC-series mounting.
The SAU replacement introduces current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S magnet model. The new SAUF variant also adds a built-in valve the SU lacked. This -H Viton seal raises operating temperature to 150 C.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X500SH 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 SAU50X500SH 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 SU50X500SH Is Used
Hot Product Diversion
Routes heated molded parts along a transfer line using the 500mm stroke and high-temp Viton seals to withstand ambient radiant heat up to 150 C.
High-Temp Pallet Pusher
Indexes freshly sterilized pallets out of a wash chamber, relying on the magnetic position feedback and robust profile body for reliable cycling.
Replacing the Airtac SU32~50 Standard Cylinder SU50X500SH with the SAU50X500SH
To replace this SU with the SAU50X500SH, confirm the 50mm bore, 500mm stroke, 1/4" port, M16x1.5 thread, and SC-series mounting. The -S magnet means you must upgrade sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. The -H Viton seal provides 150 C heat resistance. For loads needing holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. At 500mm stroke, use external guides to prevent rod bending. If downsizing, a 40mm bore yields 628 N push; if upsizing, a 63mm bore provides 1559 N. Consider the SAUF for integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU50X500SH
- ✓ 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 SU50X500SH FAQ
Yes, the SU50X500SH is discontinued. The direct replacement is the SAU50X500SH. It matches the 50mm bore, 500mm stroke, 982 N force, 1/4" port, and SC-series mounting. You simply order the SAU equivalent.
It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf max at 1.0 MPa. Because this -S model used legacy CS1-B/DS1-B switches, the SAU replacement requires current CMSG/DMSG/EMSG sensors.
