This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X85, 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 SU32X85
The AirTAC Airtac SU32~50 Standard Cylinder SU32X85 is a double-acting profile-type standard cylinder with a Ø32mm bore and 85mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X85, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X85
The AirTAC SU32X85 is a discontinued double-acting profile-type cylinder with an 85mm stroke and 32mm bore, delivering 402N push and 345N pull at 0.5MPa. AirTAC replaced it with the SAU32X85 direct replacement, preserving the exact body dimensions, 1/8" port, M10x1.25 rod thread, and SC-series mounting compatibility. The SAU upgrade also introduces the SAUF variant with a built-in 4M solenoid valve, a feature the original SU line lacked.
Because this SKU lacks a magnet, it cannot accept position sensors. If sensing is required, the SAU replacement supports modern CMSG/DMSG/EMSG switches. Note that a plain cylinder drifts on air loss; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X85 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 SAU32X85 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 SU32X85 Is Used
Small Part Clamping
Ideal for holding lightweight components during machining or assembly, utilizing the 402N push force at 0.5MPa for secure, non-marring grip.
Package Diverting
Provides reliable actuation for sorting small parcels on a conveyor line, with an 85mm stroke moving products cleanly between lanes.
Replacing the Airtac SU32~50 Standard Cylinder SU32X85 with the SAU32X85
To replace the discontinued SU32X85, order the SAU32X85, ensuring you keep the 32mm bore, 85mm stroke, 1/8" port, and SC-series mounting. If you need position sensing, this non-magnetic SKU cannot support it, but the SAU replacement can be ordered with a magnet for CMSG/DMSG/EMSG switches. When sizing, consider the 32mm bore provides 402N push at 0.5MPa; if you need more force, step up to the 40mm bore (628N). For load holding, remember the air cushion only decelerates and does not lock the piston; install a pilot-operated check valve or external rod lock to prevent drift on air loss. If your application requires integrated airflow control, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU32X85
- ✓ 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 SU32X85 FAQ
Yes, the SU32X85 is discontinued. The direct replacement is the AirTAC SAU32X85, which shares the same 32mm bore, 85mm stroke, 1/8" port, and SC-series mounting accessories. The SAU body is identical, but if you previously used the -S magnet option, note that the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
This double-acting cylinder delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical maximum of 82kgf at 1.0MPa. Because this specific SKU does not include a magnet, it cannot accept magnetic position switches. For sensing capabilities, order the SAU replacement with the -S option to use modern CMSG/DMSG/EMSG sensors.
