This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X700S, 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 SU50X700S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X700S is a double-acting profile-type standard cylinder with a Ø50mm bore and 700mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X700S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X700S
The AirTAC SU50X700S is a discontinued double-acting profile-type cylinder with a 50mm bore and 700mm stroke. AirTAC replaced this unit with the SAU50X700S, a direct alternative retaining the exact 1/4" port, M16x1.5 rod thread, and SC-series mounting.
Because this SKU includes the -S magnet, it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered. The extruded aluminum profile remains shorter and more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X700S 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 SAU50X700S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacing the Airtac SU32~50 Standard Cylinder SU50X700S with the SAU50X700S
To replace this discontinued SU50X700S, order the SAU50X700S. Verify your 1/4" port thread (PT, G, or NPT) and SC-series mounting hardware, which carry over directly. If your machine relied on the -S magnet for positioning, note that your legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the SAU. For sizing alternatives, a 40mm bore provides 628 N push at 0.5 MPa, while a 63mm bore offers 1559 N. At 700mm stroke, prevent rod bending and premature seal wear by guiding the load externally to absorb side-load forces. Remember that a standard cylinder drifts without live air; the 21mm adjustable cushions only decelerate near stroke end, so fit an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X700S
- ✓ 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 SU50X700S FAQ
Yes, the SU50X700S is discontinued. The direct replacement is the AirTAC SAU50X700S. It matches the 50mm bore, 700mm stroke, 982 N output force, 1/4" port, and SC-series mounting. You can swap it directly without altering your mechanical footprint.
This 50mm bore cylinder pushes 982 N and pulls 825 N at 0.5 MPa, pushes 1374 N at 0.7 MPa, and reaches a theoretical max of 200 kgf at 1.0 MPa. Because this SKU has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU50X700S replacement requires upgrading to CMSG/DMSG/EMSG sensors.
