This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X75N, 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 SU50X75N
The AirTAC SU32~50 Standard Cylinder SU50X75N 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 SAU50X75N, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X75N
The AirTAC SU50X75N is a discontinued double-acting profile-type cylinder with a 50mm bore and 75mm stroke. Delivering 982 N push at 0.5 MPa, it uses an extruded aluminum barrel and adjustable air cushions. The direct replacement is the SAU50X75N, matching the 1/4" port, M16x1.5 rod, and SC-series mounts.
This NBR-sealed unit operates from -20 to +70 C. Lacking a magnet, this SKU cannot accept a sensor. The SAU upgrade adds CMSG/DMSG/EMSG switch compatibility and a SAUF valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X75N 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 SAU50X75N 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 SU50X75N with the SAU50X75N
To replace this discontinued SU50X75N, order the SAU50X75N. Verify your 1/4" port, M16x1.5 thread, and SC-series mounting. Because this SKU lacks a magnet (-S), it cannot take a sensor; if sensing is needed, specify an SAU-S and use CMSG/DMSG/EMSG switches. For sizing, the 50mm bore yields 982 N push @0.5 MPa; step down to a 40mm (628 N) or up to a 63mm (1559 N) if your load shifted. Note: air cushions only decelerate; use an external rod lock for load holding. The SAUF variant integrates a valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X75N
- ✓ 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 SU50X75N FAQ
Yes, the SU50X75N is discontinued. The direct replacement is the SAU50X75N, which shares the same 50mm bore, 75mm stroke, 982 N force, 1/4" port, and SC-series mounting accessories.
It delivers 982 N push and 825 N pull @0.5 MPa, 1374 N @0.7 MPa, and a 200 kgf max @1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor. The SAU replacement with a magnet uses CMSG/DMSG/EMSG switches.
