This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X500STC, 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 SU50X500STC
The AirTAC SU32~50 Standard Cylinder SU50X500STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 500mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X500STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X500STC
The AirTAC SU50X500STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 500mm stroke. It delivers 982N push force at 0.5MPa via a 1/4 inch port. AirTAC replaced it with the SAU50X500STC, a direct alternative retaining the exact bore, stroke, force, port and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. The -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in-valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X500STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X500STC 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 SU50X500STC Is Used
Package Diversion
Pushes cartons laterally across a conveyor belt using the 982N push force at 0.5MPa, with the TC mount providing a stable pivot for the 500mm stroke.
Component Ejection
Ejects machined parts from a fixture, relying on the 21mm adjustable air cushions at both ends to decelerate the payload smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU50X500STC with the SAU50X500STC
To replace this SU50X500STC, order the SAU50X500STC. Confirm the 50mm bore, 500mm stroke, M16x1.5 rod thread, 1/4 inch port (PT/G/NPT) and TC mounting interface. Because this -S SKU has a magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For sizing both ways, a 40mm bore yields 628N push at 0.5MPa, while a 63mm bore yields 1559N. A plain cylinder drifts without live air; the 21mm cushions only decelerate, so use an external rod lock or pilot-operated check valve for load holding. At 500mm stroke, prevent rod bending by guiding the load externally. If valve integration is needed, explore the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X500STC
- ✓ 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 SU50X500STC FAQ
Yes, the SU50X500STC is discontinued. The direct replacement is the SAU50X500STC. It shares the same 50mm bore, 500mm stroke, 982N force, 1/4 inch port and TC mounting, so it fits the same application directly.
At 0.5MPa it provides 982N push and 825N pull force, reaching 1374N at 0.7MPa and a theoretical max of 200kgf at 1.0MPa. The -S magnet on this legacy model used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
