This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X75S, 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 SU50X75S
The AirTAC SU32~50 Standard Cylinder SU50X75S is a double-acting profile-type standard cylinder with a Ø50mm bore and 75mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X75S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X75S
The AirTAC SU50X75S is a discontinued double-acting profile-type cylinder with a 50mm bore and 75mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X75S, a direct upgrade retaining the exact body, stroke, force, and SC-series mounting footprint.
The SAU replacement modernizes the sensor groove: your legacy CS1-B/DS1-B switches make way for current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, which the SU family lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X75S 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 SAU50X75S 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 SU50X75S Is Used
Component Clamping
Ideal for securing mid-weight machined parts during milling or drilling, utilizing the 982N push force at 0.5MPa for rigid, deflection-free holding.
Pallet Stop Gates
Controls lowerator entry gates in pallet flow systems, benefiting from the compact profile body that saves space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU50X75S with the SAU50X75S
To replace the SU50X75S, order the SAU50X75S and confirm the 1/4" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, you must upgrade your position sensing from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG family. If your application needs self-switching without external plumbing, consider the SAUF50X75S which integrates a 4M solenoid valve directly on the body. When sizing, the 50mm bore yields 982N push at 0.5MPa; stepping down to a 40mm bore drops this to 628N, while an 80mm bore provides 2513N. For any load that must remain suspended if air pressure drops, note that the air cushions only decelerate the piston near stroke end and do not act as a brake—install an external rod lock or pilot-operated check valve for secure holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X75S
- ✓ 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 SU50X75S FAQ
Yes, the SU50X75S is discontinued and end-of-life. The direct replacement is the AirTAC SAU50X75S. It shares the identical 50mm bore, 75mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application directly.
This double-acting cylinder provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical maximum of 200kgf at 1.0MPa. Because this model has the -S magnet option, it originally used CS1-B/DS1-B switches; the SAU50X75S replacement requires upgrading to CMSG/DMSG/EMSG sensors.
