This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X350FB, 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 SU32X350FB
The AirTAC Airtac SU32~50 Standard Cylinder SU32X350FB 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 SAU32X350FB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X350FB
The AirTAC SU32X350FB is a discontinued double-acting profile-type cylinder with a 32 mm bore and 350 mm stroke. It delivers 402 N push at 0.5 MPa and features an extruded aluminum barrel with adjustable air cushions at both ends. AirTAC replaced this legacy unit with the SAU32X350FB, a direct replacement retaining the exact bore, stroke, output force, 1/8" port, and SC-series FB mounting interface.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAU upgrade also introduces the SAUF valve-integrated option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X350FB 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 SAU32X350FB 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 SU32X350FB Is Used
Package Diverting
Ideal for pushing lightweight parcels on a sorting line where the 402 N force at 0.5 MPa easily handles cardboard without crushing the contents.
Small Part Ejection
Provides reliable ejection of machined small components from a fixture, utilizing the 350 mm stroke to clear the work area completely.
Replacing the Airtac SU32~50 Standard Cylinder SU32X350FB with the SAU32X350FB
To replace the SU32X350FB, order the SAU32X350FB and verify your 1/8" port thread (PT, G, or NPT) along with the SC-series FB mounting accessory. This non-magnetic SKU cannot support sensors, but if you need detection on the new unit, the SAU family uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If your application requires a higher load, the adjacent 40 mm bore provides 628 N push at 0.5 MPa. Note that a plain cylinder drifts on air loss; the cushions only decelerate, so use an external rod lock or pilot-operated check valve for held loads. Finally, at 350 mm, the 12 mm rod is susceptible to bending, so use an external guide to prevent side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU32X350FB
- ✓ 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 SU32X350FB FAQ
Yes, the AirTAC SU32X350FB is discontinued. The direct replacement is the SAU32X350FB. It shares the identical 32 mm bore, 350 mm stroke, output force, 1/8" port, and SC-series FB mounting, so it fits the same application directly.
The force ratings are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor. If you order the SAU replacement with a magnet (-S), it uses CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B.
