This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X125SN, 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 SU32X125SN
The AirTAC SU32~50 Standard Cylinder SU32X125SN is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X125SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X125SN
The AirTAC SU32X125SN is a discontinued double-acting profile-type cylinder with a 32 mm bore and 125 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this legacy unit with the SAU32X125SN, a direct alternative retaining the exact bore, stroke, output force, port size, and SC-series mounting footprint.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the older CS1-B/DS1-B switches used on this SU -S magnet model, and adds an optional SAUF built-in 4M solenoid valve. The compact extruded aluminum body is shorter than an ISO 15552 cylinder of the same bore, and the NBR seal supports standard -20 to +70 C operation.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X125SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU32~50 Standard Cylinder SU32X125SN Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using a safe 241 N working load.
Package Diverting
Actuates a short 125 mm stroke diverter arm to route small parcels on a conveyor belt line.
Compact Clamping
Fits into tight machine cells to hold parts steady, benefiting from the short profile body design.
Replacing the Airtac SU32~50 Standard Cylinder SU32X125SN with the SAU32X125SN
To replace the SU32X125SN, order the SAU32X125SN direct equivalent, confirming the 32 mm bore, 125 mm stroke, M10x1.25 rod thread, and 1/8" port. Because this SKU includes a magnet (-S), note that the legacy CS1-B/DS1-B switches must change to the SAU's CMSG/DMSG/EMSG sensor family. If your application needs a self-switching function, consider the SAUF variant with its integrated 4M valve. For sizing both ways, a neighboring 40 mm bore provides higher force (628 N push at 0.5 MPa), while dropping pressure below 0.5 MPa reduces output. At 125 mm stroke, side-load bending is minimal, but always guide the load to prevent rod damage. A plain cylinder does not hold load on air loss; the 21 mm adjustable cushion only decelerates near stroke end, so add an external rod lock or pilot-operated check valve for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAU32X125SN
- ✓ 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 SU32X125SN FAQ
Yes, the AirTAC SU32X125SN is discontinued. The direct replacement is the SAU32X125SN. It shares the identical 32 mm bore, 125 mm stroke, 1/8" port, and SC-series mounting, so it bolts right in. The main change is that the SAU uses modern CMSG/DMSG/EMSG sensors instead of the older CS1-B/DS1-B switches.
This double-acting 32 mm bore cylinder features a 1/8" port and generates 402 N push and 345 N pull at 0.5 MPa. At 0.7 MPa it pushes 563 N, and at 0.9 MPa it reaches 724 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The unit operates at 30-800 mm/s and has a 21 mm adjustable air cushion at both ends.
