This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAU50X175S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAU50X175S in place of this model. 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 SU50X175S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X175S is a double-acting profile-type standard cylinder with a Ø50mm bore and 175mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAU50X175S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X175S
The AirTAC SU50X175S is a discontinued double-acting profile-type cylinder with a 50mm bore and 175mm stroke. It features an extruded aluminum barrel and adjustable air cushions at both ends, offering a shorter, more compact footprint than an ISO 15552 cylinder of the same bore while sharing AirTAC SC-series mounting accessories. Delivering 982 N push and 825 N pull at 0.5 MPa, it is replaced drop-in by the SAU50X175S.
The SAU50X175S retains the exact body, bore, stroke, force, 1/4" port, and SC-series mounts. For your sizing, the safe working load is roughly 589 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 50 kg with a 2:1 safety margin. This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces the SAUF built-in 4M solenoid valve variant, an integrated self-switching option the SU series never offered.
Airtac SU32~50 Standard Cylinder SU50X175S Technical Specifications

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X175S 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 SAU50X175S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU50X175S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×175 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X175S Is Used
Package Diverting
Pushes cartons off a main conveyor line using 982 N of thrust at 0.5 MPa, with the 175mm stroke clearing side guides cleanly.
Pallet Stop Gate
Acts as a pneumatic stop for low-profile pallets, where the compact extruded barrel fits tight conveyor frame clearances.
Component Clamping
Holds light aluminum extrusions during machining, utilizing the 825 N pull force and adjustable end cushions for smooth operation.
Replacing the Airtac SU32~50 Standard Cylinder SU50X175S with the SAU50X175S
To replace this SU50X175S, order the SAU50X175S. Confirm the 1/4" port (default PT, with G or NPT available), the M16x1.5 rod-end thread, and your SC-series mounting hardware (LB/FA/FB/CA/CB). Because this is an -S magnet model, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new SAU. For sizing both ways: a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N, compared to this 50mm bore's 982 N. A plain cylinder does not hold load on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads. At 175mm stroke, rod bending is low, but always guide the load to prevent side-load wear. If you need self-switching, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X175S
- ✓ 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 SU50X175S FAQ
Yes, the AirTAC SU50X175S is discontinued and end-of-life. The exact drop-in replacement is the SAU50X175S. It shares the identical 50mm bore, 175mm stroke, output force, 1/4" port, and SC-series mounting accessories, so it fits the same application directly.
The 50mm bore delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this is an -S model, it uses a piston magnet with legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to current CMSG/DMSG/EMSG sensors.
