This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X115, 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 SU32X115
The AirTAC Airtac SU32~50 Standard Cylinder SU32X115 is a double-acting profile-type standard cylinder with a Ø32mm bore and 115mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X115, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X115
The AirTAC SU32X115 is a discontinued double-acting profile-type cylinder with a 32mm bore and 115mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8" port. Because 115mm is a non-standard stroke, it requires precise sizing. The direct replacement is the SAU32X115, matching the bore, output force, port size and SC-series mounting.
This extruded aluminium body is more compact than an ISO 15552 equivalent. Note this non-magnetic SKU cannot take a sensor; legacy -S versions used CS1-B/DS1-B switches, while the SAU upgrade uses CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X115 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 SAU32X115 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 SU32X115 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably knock lightweight molded parts out of a machining fixture.
Package Diverting
Short 115mm stroke actuates a routing gate to sort small boxes on a packaging line without taking up much space.
Stopper Arm
Acts as a pneumatic stop for totes on a roller conveyor, holding safely with a 241N working load limit.
Replacing the Airtac SU32~50 Standard Cylinder SU32X115 with the SAU32X115
To replace this discontinued SU32X115, order the SAU32X115 direct equivalent, verifying your 1/8" port thread (PT/G/NPT), M10x1.25 rod end, and SC-series mounting (LB/FA/FB/CA/CB). If moving up, a 40mm bore yields 628N push at 0.5MPa; stepping down is not advised for this class. Since 115mm is a non-standard stroke, confirm dimensions. At 115mm side-load risk is minimal, but always guide the load. This non-magnetic version cannot accept a sensor. A plain cylinder drifts on air loss—the 21mm cushions only decelerate—so use an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated variant is available if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X115
- ✓ 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 SU32X115 FAQ
Yes, the AirTAC SU32X115 is discontinued. The direct replacement is the SAU32X115. It shares the same 32mm bore, 115mm stroke, 1/8" port, force output, and SC-series mounting accessories, fitting the exact same application envelope.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor. Legacy SU -S models used CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors.
