This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAU50X880S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAU50X880S 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 SU50X880S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X880S is a double-acting profile-type standard cylinder with a Ø50mm bore and 880mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAU50X880S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X880S
The AirTAC SU50X880S is a discontinued double-acting profile-type cylinder with an 880 mm stroke. It delivers 982 N push force at 0.5 MPa through a 50 mm bore and 1/4" port. The exact drop-in replacement is the SAU50X880S, matching the stroke, force, and SC-series mounting.
When upgrading, the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model. The SAU also adds a SAUF built-in-valve option. For sizing, the safe working load is roughly 589 N (60% of push), allowing a 50 kg vertical lift with a 2:1 margin. Note that 880 mm strokes require external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X880S 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 SAU50X880S 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.

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 SU50X880S Is Used
Long-Stroke Diversion
Pushes packages across a 880 mm conveyor lane using the 982 N push force at 0.5 MPa, requiring external guides to prevent rod bending.
Vertical Material Lift
Raises components up to 50 kg with a 2:1 safety margin, relying on a pilot-operated check valve to hold the load securely.
Automated Press Ejection
Ejects parts from a press over an extended 880 mm distance, utilizing the 21 mm adjustable air cushions to decelerate the load.
Replacing the Airtac SU32~50 Standard Cylinder SU50X880S with the SAU50X880S
To replace this discontinued SU50X880S, order the SAU50X880S drop-in equivalent, ensuring you keep the 50 mm bore, 880 mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this is an -S magnet model, you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. Sizing alternatives: if you need less force, step down to a 40 mm bore (628 N push @0.5 MPa); if you need more, step up to a 63 mm bore (1559 N push @0.5 MPa). For the 880 mm stroke, always use an external guide to prevent rod bending and side-load damage. A plain cylinder will not hold a load without air; use an external rod lock or pilot-operated check valve for secure holding. The SAUF variant offers a built-in 4M solenoid valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU50X880S
- ✓ 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 SU50X880S FAQ
Yes, the SU50X880S is discontinued. The exact drop-in replacement is the AirTAC SAU50X880S. It shares the exact same 50 mm bore, 880 mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application. You just order the SAU50X880S.
The 50 mm bore provides 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 your old model has an -S magnet, you must upgrade from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors on the SAU.
