This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X500, 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 SU32X500
The AirTAC SU32~50 Standard Cylinder SU32X500 is a double-acting profile-type standard cylinder with a Ø32mm bore and 500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X500, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X500
The AirTAC SU32X500 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 500 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8 inch port. The direct replacement is the SAU32X500, matching the bore, stroke, force, port and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade also switches to CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X500 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 SAU32X500 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 SU32X500 Is Used
Diverting Arms
Drives light-duty diverting mechanisms on packaging lines where the 402 N push force easily overcomes friction.
Small Part Ejection
Executes 500 mm ejection strokes to clear small molded parts from press beds into collection bins.
Vertical Lowering
Lowers lightweight 20 kg fixtures safely, relying on adjustable end cushions to decelerate at the bottom.
Replacing the Airtac SU32~50 Standard Cylinder SU32X500 with the SAU32X500
To replace this SU32X500, order the SAU32X500. Verify your 1/8 inch port thread (PT, G or NPT) and SC-series mounting. Since this is a non-magnet SKU, it cannot take a switch; if sensing is needed, order an SAU with -S and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. At 0.5 MPa the 32 mm bore yields 402 N push and 345 N pull; if undersized, step up to the 40 mm bore (628 N push). For the 500 mm stroke, use an external guide to prevent rod bending. The cylinder will not hold load without air; add a rod lock or pilot check valve. Consider the SAUF for built-in valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU32X500
- ✓ 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 SU32X500 FAQ
Yes, the SU32X500 is discontinued. The direct replacement is the SAU32X500, offering identical 32 mm bore, 500 mm stroke, force, 1/8 inch port and SC-series mounting.
It provides 402 N push and 345 N pull at 0.5 MPa, 563 N at 0.7 MPa, and a max of 82 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot take a sensor. The SAU replacement with -S uses CMSG/DMSG/EMSG switches.
