This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X75STC, 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 SU32X75STC
The AirTAC Airtac SU32~50 Standard Cylinder SU32X75STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X75STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X75STC
The AirTAC SU32X75STC is a discontinued double-acting profile-type cylinder featuring a 32 mm bore, 75 mm stroke, and a 1/8" port. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore while sharing AirTAC SC-series mounting accessories. It delivers 402 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU32X75STC, a direct upgrade retaining the exact bore, stroke, output force, port size, and TC mounting interface.
Buyers should note two key upgrade facts: the SAU replacement transitions from the older CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family, and it introduces the SAUF built-in 4M solenoid valve option the SU line lacked. Note that a plain cylinder drifts without live air; the cushion only decelerates.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X75STC 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 SAU32X75STC 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 SU32X75STC Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight machined components out of a fixture on an assembly line.
Package Routing
Actuates a 75 mm stroke diverting arm to sort small boxes on a conveyor, guided safely by the TC mount.
Replacing the Airtac SU32~50 Standard Cylinder SU32X75STC with the SAU32X75STC
To replace the discontinued SU32X75STC, order the SAU32X75STC direct equivalent, verifying the 1/8" port, M10x1.25 rod thread, and TC mounting accessory are retained. Because this SKU includes a magnet (-S), you must migrate from the legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. Size both ways: dropping to a smaller bore loses thrust, while stepping up to a 40 mm bore increases push force to 628 N at 0.5 MPa. At 75 mm stroke, side-load risks are minimal, but always guide the load to prevent rod bending. If the machine requires load holding during air loss, add an external rod lock or pilot-operated check valve, as standard air cushions only decelerate. For automated actuation, consider the SAUF variant with its integrated valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X75STC
- ✓ 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 SU32X75STC FAQ
Yes, the AirTAC SU32X75STC is discontinued. The direct replacement is the SAU32X75STC. It matches the 32 mm bore, 75 mm stroke, 1/8" port, output force, and TC mounting interface, fitting the same application.
The 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this model has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
