This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAU50X715S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAU50X715S 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 SU50X715S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X715S is a double-acting profile-type standard cylinder with a Ø50mm bore and 715mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAU50X715S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X715S
The AirTAC SU50X715S is a discontinued double-acting profile-type cylinder with a 50mm bore and 715mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore and delivers 982 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU50X715S, a true drop-in replacement retaining the exact bore, stroke, force, 1/4" port, and SC-series mounting.
Because this SKU includes the -S magnet, it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve the SU never offered. For sizing, a safe working load is roughly 589 N (60% of the 0.5 MPa push), equating to a 50 kg vertical lift with a 2:1 safety margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X715S 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 SAU50X715S 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 SU50X715S Is Used
Long-Stroke Diverting
Pushes packages across a 715mm conveyor lane using the 982 N push force at 0.5 MPa, guided externally to prevent rod bending.
Vertical Lift Gate
Raises a 50kg access panel with a 2:1 safety margin, requiring a pilot-operated check valve to hold the load securely on air loss.
Material Ejection
Ejects machined parts from a fixture over a 715mm distance, relying on the 21mm adjustable air cushions to decelerate the 20mm rod smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU50X715S with the SAU50X715S
To replace this discontinued SU50X715S, order the SAU50X715S, confirming the 50mm bore, 715mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). If your -S magnet was used with CS1-B/DS1-B switches, you must switch to CMSG/DMSG/EMSG sensors on the SAU. When sizing, a 40mm bore gives 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N. Note that a plain cylinder does not hold load on air loss—the 21mm adjustable cushion only decelerates—so use an external rod lock or pilot-operated check valve for holding. At 715mm, this long stroke demands an external guide to prevent rod bending and side-load wear. For self-switching needs, consider the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU50X715S
- ✓ 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 SU50X715S FAQ
Yes, the SU50X715S is discontinued. The exact drop-in replacement is the AirTAC SAU50X715S. It matches the 50mm bore, 715mm stroke, 1/4" port, and SC-series mounting. The main change is that your legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the SAU.
The 50mm bore features a 1/4" air port and a 20mm piston rod. It 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. Operating speed is 30-800 mm/s.
