This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X800, 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 SU32X800
The AirTAC Airtac SU32~50 Standard Cylinder SU32X800 is a double-acting profile-type standard cylinder with a Ø32mm bore and 800mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X800, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X800
The AirTAC SU32X800 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 800 mm stroke. Built with an extruded aluminum barrel, it delivers 402 N push force at 0.5 MPa and operates at speeds of 30-800 mm/s via its 1/8" port. AirTAC replaced this unit with the SAU32X800, a direct replacement matching the exact bore, stroke, output force, port size, and SC-series mounting.
When upgrading to the SAU32X800, the body dimensions remain identical, but the legacy CS1-B/DS1-B sensors are replaced by the modern CMSG/DMSG/EMSG switch family. Note that this specific SU SKU lacks a magnet, so it cannot accept any sensor without changing the piston. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X800 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 SAU32X800 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 SU32X800 Is Used
Light Package Diversion
Pushes small cardboard cartons across a sorting line using the 402 N push force, with the 800 mm stroke covering the full conveyor belt width.
Compact Vertical Lift
Raises lightweight tote bins up to 20 kg in a dense storage rack, benefiting from the short profile body to save vertical headroom.
Long-Reach Part Ejector
Clears stamped small parts from a press bed over an 800 mm distance, requiring external guide rails to prevent rod bending during ejection.
Replacing the Airtac SU32~50 Standard Cylinder SU32X800 with the SAU32X800
To replace the SU32X800, order the SAU32X800. Confirm your 1/8" port thread (PT, G, or NPT) and SC-series mounting accessories (LB, FA, FB, CA, CB, TC, TCM1), as these remain identical. Because this SKU has no magnet (-S), it cannot support position sensing; if you need switches, select an SAU32X800S and use CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For load sizing, the 32 mm bore yields 402 N push and 345 N pull at 0.5 MPa; if you need more force, step up to a 40 mm bore (628 N push). A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. Finally, the 800 mm stroke demands external guide rails to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU32X800
- ✓ 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 SU32X800 FAQ
Yes, the SU32X800 is discontinued. The direct replacement is the AirTAC SAU32X800. It shares the same 32 mm bore, 800 mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it fits the same application without modifications.
At 0.5 MPa it provides 402 N push and 345 N pull; at 0.7 MPa it pushes 563 N, and the theoretical max is 82 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept sensors. If you order the SAU32X800S replacement with a magnet, you must use the current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
