This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAU50X75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAU50X75 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.

The AirTAC Airtac SU32~50 Standard Cylinder SU50X75 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 drop-in replacement is the SAU50X75, which matches its bore, stroke, force and mounting.
The AirTAC SU50X75 is a discontinued double-acting profile-type cylinder with a 50mm bore and 75mm stroke. It delivers 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced this unit with the SAU50X75, a true drop-in equivalent sharing the exact bore, stroke, output force, port size and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept a sensor. If you need position detection, the SAU50X75S uses modern CMSG/DMSG/EMSG switches, whereas the legacy SU used CS1-B/DS1-B. For sizing, a safe working load is roughly 589N (60% of the 0.5MPa push), allowing a 50kg vertical lift with a 2:1 margin. The SAU family also adds a SAUF variant with a built-in valve the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X75 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|

| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X75 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.

| ×75 | 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.
Pushes light to medium cartons at 30-800 mm/s on packaging lines, utilising the 982N push force to actuate routing gates without overshooting.
Acts as a pneumatic stop for inbound pallets, absorbing kinetic energy via the 21mm adjustable air cushions at both ends of the 75mm stroke.
Secures workpieces during machining, offering a safe working load of 589N to hold components firmly against cutting forces.
To replace the SU50X75, order the SAU50X75. Confirm your 1/4" port, M16x1.5 rod thread and SC-series mounting. This non-magnetic SKU cannot hold a load without live air; the cushions only decelerate, so use an external rod lock or pilot-operated check valve for vertical holding. If you need more force, the 63mm bore yields 1559N push at 0.5MPa; if less is required, the 40mm bore provides 628N. The SAUF version integrates a 4M solenoid valve for self-switching if you want to simplify plumbing.
Replacement checklist
Yes, the SU50X75 is discontinued. The exact drop-in replacement is the AirTAC SAU50X75. It shares the identical 50mm bore, 75mm stroke, 982N force at 0.5MPa, 1/4" port and SC-series mounting, so it fits the same application directly.
The 50mm bore provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. This specific non-magnetic SKU cannot take a sensor; the SAU50X75S uses CMSG/DMSG/EMSG switches, replacing the legacy CS1-B/DS1-B.
