This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X250SH, 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 SU50X250SH
The AirTAC SU32~50 Standard Cylinder SU50X250SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 250mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X250SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X250SH
The AirTAC SU50X250SH is a discontinued double-acting profile cylinder with a 50mm bore and 250mm stroke. It delivers 982N push force at 0.5MPa. AirTAC replaced this unit with the SAU50X250SH, a direct upgrade retaining the exact bore, stroke, 1/4" port, and SC-series mounting.
This legacy unit features a Viton H high-temperature seal rated for 0-150C and a piston magnet for CS1-B/DS1-B switches. The SAU replacement upgrades the sensor groove to current CMSG/DMSG/EMSG switches and introduces the SAUF built-in 4M valve option. The extruded aluminum body is more compact than an ISO 15552 cylinder, and the 21mm cushions only decelerate; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X250SH 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 SAU50X250SH 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 SU50X250SH Is Used
Hot End Ejection
Clamping and ejecting parts at elevated temperatures using the Viton H seal rated for 0-150C environments.
Mid-Stroke Diversion
Pushing items on a line using the 250mm stroke, providing 982N push force at 0.5MPa for reliable routing.
Replacing the Airtac SU32~50 Standard Cylinder SU50X250SH with the SAU50X250SH
To replace this discontinued SU50X250SH, order the SAU50X250SH. Confirm the 1/4" port, M16x1.5 rod thread, and SC-series mounting accessories. Because the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. The -H Viton seal handles 0-150C. If sizing alternatives, the neighboring 40mm bore yields 628N push at 0.5MPa, while the 63mm bore yields 1559N. For this 250mm stroke, guide the load to prevent rod bending. A plain cylinder drifts on air loss; add a pilot-operated check valve for holding. The SAUF valve-integrated variant is available if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X250SH
- ✓ 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 SU50X250SH FAQ
Yes, the SU50X250SH is discontinued. The direct replacement is the SAU50X250SH. It shares the same 50mm bore, 250mm stroke, 1/4" port, and SC-series mounting, but the SAU uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 50mm bore features a 1/4" air port. It provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. The 21mm cushions decelerate the load but do not hold it without live air.
