This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X350, 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 SU32X350
The AirTAC SU32~50 Standard Cylinder SU32X350 is a double-acting profile-type standard cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X350, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X350
The AirTAC SU32X350 is a discontinued double-acting profile-type cylinder featuring a 32mm bore and 350mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore and delivers a thrust of 402 N at 0.5 MPa. AirTAC replaced this legacy unit with the SAU32X350, a direct replacement retaining the exact bore, stroke, output force, 1/8" port, and SC-series mounting compatibility.
Buyers should note two key upgrade facts: the SAU line introduces a SAUF variant with a built-in 4M solenoid valve the SU lacked, and the SAU uses current CMSG/DMSG/EMSG sensors. Because this specific SU32X350 SKU has no magnet, it cannot accept any magnetic switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X350 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 SAU32X350 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 SU32X350 Is Used
Package Diverting
Actuates routing gates on 24V DC conveyor lines, using the 350mm stroke to shift lightweight totes between parallel transport lanes.
Small Part Ejection
Pushes machined components out of CNC fixtures, applying a safe 241 N working load to clear the work area for the next cycle.
Replacing the Airtac SU32~50 Standard Cylinder SU32X350 with the SAU32X350
To replace the discontinued SU32X350, order the SAU32X350 direct equivalent, confirming the 32mm bore, 350mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting. Since this SKU lacks a magnet (-S), it cannot support sensing; if detection is needed, specify an SAU32X350S and migrate to CMSG/DMSG/EMSG switches. When sizing, check neighboring bores: a 40mm bore offers 628 N push at 0.5 MPa if more force is needed, while this 32mm bore provides 402 N push and 345 N pull. For the 350mm stroke, use external guides to prevent rod bending and side-load damage. Note that a plain cylinder drifts on air loss—the cushions only decelerate—so add an external rod lock or pilot-operated check valve for load holding. The SAUF valve-integrated option can also simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU32X350
- ✓ 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 SU32X350 FAQ
Yes, the SU32X350 is discontinued. The direct replacement is the AirTAC SAU32X350. It matches the 32mm bore, 350mm stroke, 402N force at 0.5 MPa, 1/8" port, and SC-series mounting accessories, so it fits the same application without modification.
The bore is 32mm with a 1/8" port. Forces are: 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 specific SKU lacks a magnet, it cannot accept a sensor; legacy -S versions used CS1-B/DS1-B switches, while the SAU replacement uses CMSG/DMSG/EMSG sensors.
