This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X150SN, 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 SU32X150SN
The AirTAC SU32~50 Standard Cylinder SU32X150SN is a double-acting profile-type standard cylinder with a Ø32mm bore and 150mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X150SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X150SN
The AirTAC SU32X150SN is a discontinued double-acting profile-type cylinder with a 32mm bore and 150mm stroke. Featuring an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore. It delivers 402N push force at 0.5MPa via a 1/8" port. The direct replacement is the SAU32X150SN, matching the bore, stroke, force, and SC-series mounting.
This NBR-sealed unit (-N) operates from -20 to +70C. The built-in magnet (-S) works with legacy CS1-B/DS1-B switches, whereas the SAU upgrade uses current CMSG/DMSG/EMSG sensors and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X150SN carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU32X150SN 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 SU32X150SN Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject lightweight molded components from a fixture, fitting neatly into tight machine cells.
Package Diverting
Pushes small cartons on a conveyor line with a 150mm stroke, benefiting from the NBR seals in standard indoor ambient conditions.
Replacing the Airtac SU32~50 Standard Cylinder SU32X150SN with the SAU32X150SN
To replace this SU32X150SN, order the SAU32X150SN. Confirm the 32mm bore, 150mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting are identical. Because this SKU has a magnet (-S), note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need higher force, the neighboring 40mm bore yields 628N push at 0.5MPa; if lower force is acceptable, there is no smaller standard profile bore. For stroke lengths of 150mm or more, ensure adequate guiding to prevent rod-bending side loads. A plain cylinder does not hold load without live air; the 21mm cushions only decelerate. For load holding on air loss, add an external rod lock or pilot-operated check valve. If self-switching is needed, explore the SAUF variant with its built-in 4M solenoid valve, an option the SU line lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU32X150SN
- ✓ 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 SU32X150SN FAQ
Yes, the SU32X150SN is discontinued. The direct replacement is the SAU32X150SN. It offers the same 32mm bore, 150mm stroke, 402N force at 0.5MPa, 1/8" port, and SC-series mounting. However, the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa, speed is 30-800mm/s, and the NBR seals allow operation from -20 to +70C.
