This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X820S, 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 SU32X820S
The AirTAC SU32~50 Standard Cylinder SU32X820S is a double-acting profile-type standard cylinder with a Ø32mm bore and 820mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X820S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X820S
The AirTAC SU32X820S is a discontinued double-acting profile cylinder with an 820 mm stroke and 32 mm bore, delivering 402 N push force at 0.5 MPa. AirTAC replaced this end-of-line unit with the SAU32X820S, a direct upgrade retaining the exact bore, stroke, 1/8" port, and SC-series mounting footprint.
This compact extruded-aluminum body is shorter than an ISO 15552 equivalent. The -S magnet on this legacy SKU worked with CS1-B/DS1-B switches, but the SAU replacement requires current CMSG/DMSG/EMSG sensors. Note the SAU family also adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X820S 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 SAU32X820S 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 SU32X820S Is Used
Long-Reach Diversion
Pushes light packages across a sorting line using the 820 mm stroke, guided externally to prevent rod bending during the 402 N push cycle.
Compact Assembly Ejector
Fits in tight machine cells where an ISO cylinder would be too long, using the shorter profile body and 1/8" ports to eject machined parts.
Replacing the Airtac SU32~50 Standard Cylinder SU32X820S with the SAU32X820S
To replace this SU32X820S, order the SAU32X820S direct equivalent, verifying your 1/8" port thread (PT/G/NPT) and SC-series mounting (LB/FA/FB/CA/CB). Because this 820 mm stroke exceeds 300 mm, you must support side loads with an external guide to prevent rod bending. If you need more force, neighboring bores like the 40 mm offer 628 N push at 0.5 MPa. The -S magnet means you must upgrade sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. The air cushion only decelerates the piston; it does not hold load on air loss, so add an external rod lock for vertical safety. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X820S
- ✓ 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 SU32X820S FAQ
Yes, the SU32X820S is discontinued. The direct replacement is the SAU32X820S, which shares the identical 32 mm bore, 820 mm stroke, 1/8" port, output force, and SC-series mounting.
It 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. The -S magnet used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
