This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X525S, 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 SU50X525S
The AirTAC SU32~50 Standard Cylinder SU50X525S is a double-acting profile-type standard cylinder with a Ø50mm bore and 525mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X525S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X525S
The AirTAC SU50X525S is a discontinued double-acting profile-type cylinder with a 50mm bore and 525mm stroke. Delivering 982 N push force at 0.5 MPa, it features an extruded aluminum barrel and adjustable air cushions at both ends. AirTAC replaced this legacy unit with the SAU50X525S, a direct upgrade retaining the exact bore, stroke, output force, 1/4" port, and SC-series mounting compatibility.
When migrating to the SAU50X525S, note that the built-in magnet now pairs with current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors. The new SAU family also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X525S 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 SAU50X525S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Ejects machined parts from a fixture over a 525mm distance, relying on adjustable end cushions.
Replacing the Airtac SU32~50 Standard Cylinder SU50X525S with the SAU50X525S
To replace the SU50X525S, order the SAU50X525S and verify your 1/4" port, M16x1.5 rod thread, and SC-series mounting accessories. Because this SKU includes a magnet, you must upgrade your legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. If you need integrated flow control, explore the SAUF valve-integrated option. For loads requiring 1374 N push force at 0.7 MPa, the 50mm bore is sufficient; if less force is acceptable, step down to a 40mm bore. Remember that a plain cylinder does not hold load on air loss—the cushion only decelerates—so use an external rod lock for vertical holding. At 525mm, this long stroke demands external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU50X525S
- ✓ 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 SU50X525S FAQ
Yes, the SU50X525S is discontinued. The direct replacement is the AirTAC SAU50X525S. It matches the 50mm bore, 525mm stroke, 1/4" port, and SC-series mounting, but requires upgrading your -S magnet sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG.
The 1/4" port bore delivers 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 speed is 30-800 mm/s.
